I was a bad boy.


I was doing a little hole shot to get some pictures of the tires blazzing.


Did 1 and my friend didnt get a good picture so I did another one but when I was power braking it and it shifted into second gear the tires stopped spinninghttp://www.dieselplace.com/forum/smileys/Cry.gif


I backed up a little and then I noticed the tranny was slipping


Now my DIC says "Range Shift Inhibited"


I have reverse but when I put it into Drive it seems like the tranny barely catches like maybe 3rd gear then if I sit a couple more seconds the DIC tells me range shift inhibited and it seems like it shifts into nuetral and the little light under the gear selected starts flashing.


I have let the truck and tranny cool off for a hour and tried cycling the key about 20 times already but still nothing.


Anyone have any ideas?


Will it reset itself or do I need to go to the dealer for reset?


And I'm not home either which is not good.http://www.dieselplace.com/forum/smileys/Cry.gif


Any ideas? I'm desperate.


I'll be sitting hear quietly whimperinghttp://www.dieselplace.com/forum/smileys/Cry.gif


Diesel Dragon

http://www.dieselplace.com/forum/smileys/Cry.gif Mine did something similar the other day. One cycle of the key and it was back to normal. NSBU swtich??

Sucking air through the sump filter will do the same thing. Check fluid first. If the fluid is full, clear codes in trans. If you don't clear the codes it won't work.


mike

It's continues to default limp every time he tries to roll out once D is selected and he only has third gear ... It will shift in 4 wheel drive ...


I think something electrical came lose or failed ....NSBU is Tan and fairly new ....That would be best case scenerio ... Worst, well Bellevue washer and C1 come to mind but I highly doubt it ....It is acting like the time I ......


Good luck Diesel Dragon

Mac, you didn't! Did you? http://www.dieselplace.com/forum/smileys/HiHi.gif


mike

Mac,


that's what i was thinking.. no go in first.. he's got a juice and a VA.. hopefully c1 didn't get wasted.. i doubt it given the abuse you gave your original C1 and it held...http://www.dieselplace.com/forum/smileys/HiHi.gif

Mac DG symtoms are so similar to the ride http://www.dieselplace.com/forum/smileys/Nuke.gif you took me on.

Mike


Wasn't there .... http://www.dieselplace.com/forum/smileys/Embarrased.gif





Nick


Only had the Juice on ...





Hoot


You aint kidding ,sounds just like it but hard to imagine with the stock C1's it happened but it is a Dually sooooooo .... Spinning 4 verses 2 is alot more force but my stock C1's looked good ...Wasn't stock C1's we http://www.dieselplace.com/forum/smileys/Nuke.gif.....





Mac

Ok update for today.


I had the truck towed to a dealer with a good reputation (thx Mack) Luckily it was a Heavy International wrecker and not a furd or dudge tow truck, that would of been embarassing.http://www.dieselplace.com/forum/smileys/Embarrased.gif


I went to the dealer after work and the service writer came out with me and we hooked up the Tech 2. I had some old engine codes from the mass air sensor and the VSS, and 1 security from my remote start, 2 cruise control ones from my high idle insall I think but no important codes.


And more importantly NO tranny codes, infact the Tech 2 couldnt find the tranny, it couldn't communicate with it. if we tried to command a gear selection it would just say communication lost.Even with the truck running and the DIC saying Range Shift Inhibited and the tranny not doing anything in Drive the Tech 2 didnt see a thing.


So Service Writer thinks maybe the tranny computer is fried or some of the wiring is loose or unplugged or broken. He couldnt get a mechanic to look at since it was late in the day so he will have one look at first thing Monday morning and let me know.


So no news for now....except that the dealer had no loaner Corvetteshttp://www.dieselplace.com/forum/smileys/Cry.gif


Also I dont think the tranny is limping to 3rd gear it feels more like 5th gear cuz if theres any type of incline and im talking even slight incline it won't go any where. But reverse is still strong. Good thing I'm pretty good at backing uphttp://www.dieselplace.com/forum/smileys/Big Smile.gif


Also I would like to comment on GM roadside assistance. It went very well. The lady on the phone was very nice, even though she didnt know what a "Dually" washttp://www.dieselplace.com/forum/smileys/Ermm.gif. I got the truck towed to a dealer that was not the closest one. They will tow to any dealer within 20 miles is what she said. Mine was 23 miles but she got it ok'd. And the tow truck showed up on time. So that part of the experiance went well. I called up a local towing service just in case GM wouldnt tow to dealer i wanted and the local tow driver wanted $160 so im glad GM towed it for me.


The Service writer was a good guy too and he seemed intrested in helping me with my tranny.


I'll give another report when I know something, Hopefully Monday afternoon.http://www.dieselplace.com/forum/smileys/Wink.gif


Thx for the help Diesel Dragon <IMG onMouse

Eric is a cool guy and gets the thumbs up from me ....Yes he was there for me more then once to lend a hand ... It was actually Bill (chevyhdman) who introduced me to him ... Remind him of June 5TH in South Windsor CT he needs to show at one of these events,dyno runs are on me if he has something he needs or wants to run ...


Good luck ....


Mac

Sounds alot like what my truck did.EXCEPT I had just pulled in from a fairly long trip and shut the truck down for about 30 minutes while I unloaded the trailer. Then when I cranked it up to take the trailer back it wouldn't move and I had the range inhibited displayed...


I was pretty pissed so I just went into the house. After about 20 minutes I decided that if it was the tranny or something I was gonna blow the hell out of it! It still has warranty left..only 24K on the truck. Well low and behold I hit the key and she fires right up and runs like a champ. Next day I took her in anyway the dealer to have him look at it. Seems that the switch shorted out and caused ALOT of codes.(upwards of 28). I know the service writer really well at the dealer so he had them look at everything. Then he took the truck home and back the next morning to make sure no more codes were set.


Just my story .. Sorry to hear you have one now also..GOOD LUCK !


Mike

I had that happen. Bet it's the C1 pack. Clint put the good stuff in for me. Lots of power break burn outs and high RPM launches do that stuff. Don't need to power break it any more. It spins enough on its own. Super Diesel

Hey Super Diesel what mods do you have to do burnouts with out brake torque'n it? I asked about what it would take to do this, on this site before and didn't seethe response I was looking for, sounds like you've done it.

TTS Extreme, N2O, and a little H2O mist to cool it all down. It's a 4x4 4door dooley. It's real hard on tires though. It will do it to about 60 or so miles an hour if I'm only in 2wd (or is that 4rwd). Thats hear in Denver also. At this altitude I lose about 10 hp for every 100 I make. Thats why we don't like to dyno or run 1/4 miles here. I have much more fun when I'm down at sea level. It feels like a new, more powerful truck. What ever we run in the 1/4 here, is about 1 sec. slower than we do at sea level. It's real hard to run a 12 sec. 1/4 here without max power and N2O. Super Diesel

<H1>Limp Home Mode</H1>Principle of Operation


The Allison Transmission incorporates control logic that enables the transmission to revert to a limited total hydraulic operation. The hydraulic system provides a "Limp Home" mode, allowing the operator to drive the vehicle to a service location. If power is interrupted while the transmission is operating in R (Reverse) or N (Neutral), the transmission defaults to or continues Neutral operations. The operator may turn off and restart the engine, and the shift selector will provide R (Reverse)/N (Neutral)/D (third-range) capability regardless of the range wherein the failure occurred. In this state, trim solenoid A (de-energized) allows C3 clutch to be applied. If the selector valve is moved to the reverse-range position, main pressure will be routed to C5 clutch, allowing reverse operation. If the selector valve is moved to the drive range position, main pressure will be routed to C1, allowing third-range operation.

Lonewolf do you remember which switch it was that they replaced?


Super Diesel, Hope its not the clutch packs.


GMworldclass I dont think what happened to mine was a Limp because I couldnt go anywhere. Drive felt more like 5th gear than 3rd and after a few seconds of that the gear indicated light would flash and the dic would say range shift inhibited and then it felt like the tranny shifted to nuetral by itself and I wasnt going anywhere. But reverse was still good.


Thx for all the help I'll see what happens Monday


Wonder if they have to take apart the tranny to repair I could get a shift kit and a few other goodies along with a Suncoast torque converter for them to put back in? Would save me the labor $ if they would.


Diesel Dragon

Diesel Drago


You have pulled codes and cleared them have you not? You have tried to see if that fixed the problem before you sent your Allison into surgery did you not?


mike

Diesel Dragon, I hope it's not the cluch packs also. But smells funny. The dealer will probably do it if you cough up the extra cash for the componants over what the stock parts cost, but they will record what they did and no more warranty. But when we do this no more warranty for any of us any way (tranny upgrade that is). Some dealers are good about this (some will work with you). Hope you have a good one if you go this route. You will probably be liable for hourly rate as well if they do the upgrade. Sounds like what you need though. Super Diesel

Agreed it sounds like it but If it is the C1, pack I'd be surprised ....


The Tech can command each gear but he can't communicate with the TCM the way I understand it ..... Until that is corrected there is no sense in dropping the tranny ...


Mac

Mike, I didnt have access to a scanner or tech2 so I brought it down the way it was. Although there were a few engine and body codes I think they were old and so did the service manager and they did not affect the tranny. But the weird part was that the Tech2 could not Talk to the tranny. Like it wasnt even there, no communication between the 2. So I guess they will have to figure where the break in communication is at and fix that first and then see if there is actually anything wrong with the tranny internally. The SW did reset all the codes with the tech2 but the tranny was still doing the same thing anyway.


Super Diesel, the Service manager seems cool about what happened and I told him exactly what I was doing, and he comes reccommened by other "place" members who have worked with him before with no problems about upgrades. I did pull the juice out first just in case. So just the intake and exaust left on the truck. So maybe if it comes to it and the tranny needs to come out anyway I might be able to work something out with him as far as aftermarket parts installed back in. Don't know I'll see what happens.


Mack, I hope its not the C1 pack too. But you know how us dually's are tough on drivelines, all that extra tractionhttp://www.dieselplace.com/forum/smileys/Big Smile.gif Not like those little trucks with only 2 wheels in the back http://www.dieselplace.com/forum/smileys/HiHi.gif lol


Diesel Dragon http://www.dieselplace.com/forum/smileys/Cool.gif

Talked to Service writer and he said that the Tranny has to come out because theres something broken inside.http://www.dieselplace.com/forum/smileys/Cry.gif Tranny has no forword clutches only reverse. They will pull the tranny tomm to see whats broken and then determine if they will fix it or replace with a new unithttp://www.dieselplace.com/forum/smileys/Clap.gif (or rebuilt i guess)http://www.dieselplace.com/forum/smileys/Disapprove.gif.


Any one know what the forward gears have in common that if broken would affect them all but NOT reverse?


Only good part was that I got a loaner GMC Suburban.


Tried power braking ithttp://www.dieselplace.com/forum/smileys/Big Smile.gif wouldn't even spin the single tirehttp://www.dieselplace.com/forum/smileys/Thumbs Down.gif


See what happens tomm Diesel Dragon http://www.dieselplace.com/forum/smileys/Cool.gif

C1 clutch pack is toast then ....


Hard to believe ... I put mine thru hell ....


Mac http://www.dieselplace.com/forum/smileys/Geek.gif

Mack your quick, I just posted that and I just got done PM'ing you lol

Yea, the C1s are used in all forward gears. Sorry to here that. They will probably rebuild that section. See if you can get them to put in the single sided clutches from Clint at ATS or from Suncoast. They are much more durable. But if your going to be in there, well..... Bite the bullet if you can, so you can start puttin some serious HPs down, It's worth it. It's expensive, I know. But when it's all said and done(for now). wowwwww! There's somthing to be said for a huge truck that can accelerate with some motorcycleshttp://www.dieselplace.com/forum/smileys/Shocked.gif. Super Diesel

No news from the dealer today but I did talk to Joe at Suncoast and he said it's not that hard to burn up the C1 when you do a powerbrake with a chip on the truck. He said he's repaired a bunch that have done the same thing and he's done it to his own truck which is also a dually. He said when you powerbrake it and build up 25lb plus of boost and spin the tires and then it hits 2nd gear you have over 700lbs of torque hitting at once and it over powers the clutch's.


And I guess with the dually's with the extra traction your building more power than a 2500 to break the tires loose and keep them spinning so you put a greater strain on the tranny.


So I may just let the dealer fix it stock for now and then maybe over the summer drive down and see Joe and let him do his magic.


Super Diesel, you said that you fried your's too and rebuilt it. Who's kit did you go with Suncoast or ATS, and what level up grade did you do, and have you had any problem's since or have you stayed away from powerbraking. Since you have a Dually too I was looking for a little feedback on your experiances. Thx


On another note my rental Suburban had a screw stuck in the front tire and I had to put air in it cuz it was low. So I stopped at the rental place thinking that they would send me down the street to the tire shop to get it fixed, which would of been no problem. Instead they traded me into a new white Tahoe with 1,500 miles on it http://www.dieselplace.com/forum/smileys/Big Smile.gif I'm still waiting for the Z06 Corvette but no such luck http://www.dieselplace.com/forum/smileys/Cry.gif


Diesel Dragon

I already had the ATS full house installed, but the new C1s wern't out yet. We had just learned that they were a problem. Clint got some lazer cut for me. Not one problem since. I dont power break any more. The truck has more than enough power on tap to light them easy through 3rd gear. It's a real rush for people that have never experienced that in a truck (let alone a dooley). If I launch hard, I use 4wd. One guy at work didn't believe it could light them up, so I left twin tire black marks for 200 feet for him that took 3 months to go away. The vice president of the comany (where I work) did not aprove. He told me so with a smile. Super Diesel

Hi All,


Talked to dealer and he tells me the C1 is wasted and C2 are a little burnt also http://www.dieselplace.com/forum/smileys/Cry.gif .


Dealer agreed to install Suncoast level 3 for me http://www.dieselplace.com/forum/smileys/Clap.gif. So I ordered the kit from Joe and the small parts will be here tomm and the triple converter on Monday.


Joe said that any competent tranny man that has done Alli and can read and follow directions should be able to install his kit.


I need some help from the tranny experts, Mike L. and Dmaxllitech and any one else that can help.


Are there any hints or secrets that you can help him (me) with?


I've seen something about changing the Stator support seal from brass to teflon and changing seals on some bolts and other things that are criticall for rebuild like C1 setup and other tolerances that need to be looked at very carefully. Keep in mind that tech has never done a Suncoast install so he knows none of the things you guys take as common knowledge for you field of expertise.


So any help you can share I would appreciate, so that my tranny gets built right the first time. I've been without the truck for a week already and I'm getting antsy for my Duramax again. These gas loaners just don't cut it.


So please help me so I don't cry http://www.dieselplace.com/forum/smileys/Cry.gif about a bad rebuild


Thx in advance Diesel Dragon

Your a lucky Dragon ...http://www.dieselplace.com/forum/smileys/Approve.gif


Taking into consideration your mileage I doubt you will see many worn parts besides your clutches and steels ....


Give the Tranny Guy Joe Webbs phone number for any on the spot questions ...


If you would PM me cost for reference I'd appreciate it ...I assume Eric handled the deal ...


Mac

Diesel Dragon


I would be happy to help if you need me. You or the tech can call me and i can talk him through any problem. 310 674 4400

Way to go Diesel Dragon. You will be real happy once you start really turnin the power up. Enjoy life while you can, thats what were here for. Congrats, welcome to the club. Super Diesel

In case anyone is interested my truck is STILL sitting at the dealer http://www.dieselplace.com/forum/smileys/Cry.gifhttp://www.dieselplace.com/forum/smileys/Broken Heart.gifhttp://www.dieselplace.com/forum/smileys/Angry.gifhttp://www.dieselplace.com/forum/smileys/Cry.gif


They are still waiting for some GM(Allison) gaskets or seals so they can put the tranny back together.http://www.dieselplace.com/forum/smileys/Angry.gif


I think Suncoast should include a gasket set with all there rebuild kit's.


It's a good thing I spent over $230 on next day and second day air shipping charges for the Suncoast parts so the dealer could have it back together this past Mondayhttp://www.dieselplace.com/forum/smileys/Angry.gif


And the Allison must be one Heavy tranny because when I saw my truck sitting in the parking lot the other day the front end was WAY up in the air. I thought they had pulled the motor out too. I could fit 36" tires under the front fenders no problemhttp://www.dieselplace.com/forum/smileys/Approve.gif


And to add insult to injury I had to give back the new Tahoe rental and take a POS Geo(Chevy) Tracker loaner since last Fridayhttp://www.dieselplace.com/forum/smileys/Angry.gif and it smells like my dentist office inside, like novacaine. I've exacted my anger on the poor rear tires of the Trackerhttp://www.dieselplace.com/forum/smileys/Big Smile.gif


Hope they get it together soon I'm going to Vegas next week for a little R&amp;R <IMG onMouseOver="this.style.cursor='hand'" onMouseOut="this.style.cursor=''" alt='Click on image to open in new window' onClick="window.open('smil

The only gasket you need is a transfer case adapter gasket ...


The rest should be in the Transgo kit ...If you don't have them ,I think I know where the three you need are .... I had a extra set at the dealer I didn't pick up ...That and I know where a set can be borrowed ...I could get you a set by tomorrow ...








Mac Edited by: Mackin

No offense, but show some maturity with those rental cars, they will be someones transportation one day, karma is gonna bite you in the ass and break your truck again if you keep it up.

Mack,


I'll call the dealer tomm morning again and see what's up with the gaskets. Joe told me that I needed a gasket and paper kit for the tranny to put it back together. But if the gasket's are in the TransGo kit I will tell the tech to look in there and see.





Wickedsprint,


No offense taken but karma already bit me in the ass with a broken tranny from a little power brake that's been done million's of times by other people in cars and trucks all over the world with out a problem.


And it bit me in the ass when I had a shorted ignition wire because the alarm guy was a spaz and pulled too hard on the wires and cut one on a piece of metal.


And it bit me in the ass when my Pace Edwards cover started flaking off the powder coat and now I have to change it.


And karma has bitten me in the ass hundreds of times before, so one more little nibble wouldn't hurt.


Diesel Dragon http://www.dieselplace.com/forum/smileys/Cool.gif


P.S. Just in case no one has even told you before DON'T EVER by a rental or loaner car because some one like me has driven it. http://www.dieselplace.com/forum/smileys/Big Smile.gif

If they started to delete from the Transgo kit that would be cheap ... Mine were in the bottom of the box nice and flat .... I have a used set too ,I just remembered in a pinch ...


Lord knows I bought a couple sets of these ...http://dieselplace.com/forum/smileys/Ermm.gif


You have my Cell ,I'll PM you my Business Number ....


My truck is in having some coming out of warranty work down and it's not done, so I may be in the OLds if we meet up .... I let them off the hook on a loaner ...


Be nice ...

Good news,


My truck is back together and running http://www.dieselplace.com/forum/smileys/Clap.gifhttp://www.dieselplace.com/forum/smileys/Big Smile.gifhttp://www.dieselplace.com/forum/smileys/Approve.gifhttp://www.dieselplace.com/forum/smileys/Cool.gifhttp://www.dieselplace.com/forum/smileys/Thumbs Up.gif


I picked it up this afternoon and all seems well so far. The tech said he put the tranny on fast learn, so just drive it normal.


Drove about 20 miles, got some fuel, and then put the juice back on http://www.dieselplace.com/forum/smileys/Clap.gif. I think I was having juice withdrawl symptomshttp://www.dieselplace.com/forum/smileys/Big Smile.gif.


The tranny seems to be shifting fine with a light pedal, it's still a little quirky between 1-2 on mid to full throttle, but maybe it's still learning I'll give it a few more day's before I pass judgement.


Any one who has a tranny kit have any advice on what I should be feeling between shift's or the firmness of shift's. Does the truck still defuel as much between shift's with the juice on and a shift kit installed or does it not have to do that anymore?


Also my juice seems to put out a lot more smoke off the line now on a hard acceleration than it did before. Maybe just a coincidense.


Well that's about it for now I'll give another report after the weekend and a few more miles.


Thx for everyone's help and support


Diesel Dragon http://www.dieselplace.com/forum/smileys/Cool.gifhttp://www.dieselplace.com/forum/smileys/Cool.gif&l

It will take a few shifts up and down under different throttle positions ....


Leave the Juice at that max ... Mine just rips the shifts right off ...


I had my Juice off for twenty miles do to service ,I couldn't believe the 1-2 shift flare i WAS getting once the Juice was reinstalled till it settled down ...


Drive it !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!





Mac

This has been a fun read. I am glad it all worked out. I think I will just save my money and do the entire tranny so I can have even more fun.http://www.dieselplace.com/forum/smileys/Approve.gif

Well - i just got the dreaded Range Shift Inhibited this morning. I was running about 65 and hit the throttle - It ran up to about 85 and then fell on its face. Slowed down and limped to the office. "Range Shift Inhibited" No reverse. Turned the truck off and reverse came back. Gotta go to a meeting at 1:00 then it's going to the dealer right up the road. Time for Suncoast I guess!!

Well I'd like to report that all is good with the world or at least my tranny.


Truck seems to shift well. Shifts nice and normal when under normal throttle and it hold's well under full throttle too http://www.dieselplace.com/forum/smileys/Clap.gif


I'll see if there's any power difference getting to the wheels at the next dyno day.


I have to flush out my regular tranny fluid for some synthetic this week or next once I get a Mag tranny pan.
