I put my SC V/1057 in exactly one week ago, about 4 hours ago I put in the mcrat "race" tune. I was really "driving" it for the first time and I punched it from a dead stop, 4-5th shift was real hard, then I got P0700, and the truck wouldn't move at all. Pulled over and let it sit for about 5 min, checked codes with EFI, had a couple P0700s, and P0802, and one other, but can't remember. Reset all and SLOWLY pulled away, shifted from 2-3 and then wouldn't move and SES light came on, no bang, just smooth shift then nothing. Read/reset codes again and it did it again, but this time when from 2-3 then nothing, reved it up and bang into 3rd then threw codes again, pulled into my driveway pissed:mad: Please help, I have to drive to a party tommorow 2 hours away, and I just spent all this $$ on a trans that is weaker than the stocker. Thanks

sticky solenoid? I dunno what P802 is off the top of my head, but I cant imagine something actually broke. :confuzeld: 0735 is 5th gear incorrect ratio, so I dont think you "limped" it. Hows the fluiod level? smell burnt?

Fluid is slightly above the hot marks, guage is at about 150*

smells and looks just how it did when I poured it in last weekend

You sure it wasn't the 3-4 shift? Did you reset the TAPs after program install and drive it easy till the shifts cleared up? Put it back to stock and try it.

Mike, now that I think about it, it might have been 3-4, but eiter way.

I reset the taps when I first put the trans in, and I stepped the HP levels of the programs up slowley throughout the week. I didn't reset before putting the "race" tune in.

What has me is why did it not move at all and why was it limping when I was babying it home?

When I did reset the taps, it seemed to take awhile for it to learn, and it always seemed to shift hard at higher speeds, 3-4, 4-5 shifts under hard acclleration.

Thanks again for the help.

Also, the first time it did it, when I put it in gear to try and go, other than having nothing, I got " shift range inhibited" on the display.

did you reset both taps and garage taps?

whenever I reset my taps I always go park, then drive, then reverse then neutral then drive, the neutral, then reverse, then drive, then neutral blah blah blah with my foot firmly on the brake...just seems to help the trans learn garage shifts better/faster and stop the trans from banging into gear for the next week...or is that habit/routine not doing anything for the trans at all? Before I used to do that routine with the garage taps I would sometimes get range shift inhibited when going forwards and back etc in parking lots. Not that that has anything to do with the funky 3-4 or anything tho...or does it Mike? :confused:

What tuning are you running? Ive found that TCM tuning will maybe 40% fix the goofy 3-4, the rest is all in the ECM tune itself. Base torque and torque limited injection qty ;)

I don't think I reset the garage taps, all I did was click the reset taps option when reprograming. I am running the mcrat "race" tune with stock TCM tune. I will say, the mcrat tune seemed to shift better at part throttle shifts then previous tune I had. I didn't attempt the adjust the TCM yet as I wanted to see how it would learn with the SC v in.

How would I go about reseting the garage TAPs?

Are you sure your NSBU is any good?

Are you sure your NSBU is any good?

or properly adjusted?

or properly adjusted?

Or securely plugged in?

Vernon

I see no reason why it wouldn't be any good?

How would I check?

Update...

I just went out and reset the taps, loaded the stock program back in and did what Ben suggested as far as shifting it, went out for a ride around my block and 3-4 shift wouldn't happen then the light came on, I got P0700 and P0776, pressure control solenoid B stuck off

Any suggestions? Could it be the NSBU switch, or just an adjustment?

Just curious, when did you purchase your "Sun Coast V" ?

Our records do not jive with shipping a "Sun Coast V" to NJ recently. Our records do indicate shipping a torque converter, but not a trans.
Since you are referencing Sun Coast products, I would appreciate some accurate info. Maybe Eric will chime in here.
Smoop

Sorry to hear about your troubles. My "race" tunes tend to be more trans friendly than most, and seldom have troubles with Suncoast parts since that's what we build them using.

Wish I knew more about troubleshooting trans issues. But I can guarantee that there is nothing in a McRat tune that targets 2-3 or 3-4 shifts. I do not remove the factory defuel for shifting.

I am not saying anything is wrong with the tune, the short time I ran it I was in love...Thanks!!!

As far as the trans, I bought it from Eric, who I have called and left a message with.

I just replaced the NSBU swith with no change, I did narrow it down to be stuck in 3rd gear, no up or down shifts at all.

Trans has been in the truck for exactly one week.

Here is an update after I talked with Mike last nite....

I'm not sure exactly how he put it, but what had happened was that I was in both 2nd and 3rd at the same time. The shaft that the c2 and c3 clutches are on spun and twisted the splines on the end of the shaft. I also discussed with him how the trans was shifting hard from day one. I was under the impression that between resetting the TAPs and having the shift kit installed that the shifts would be hard until it learned. Throughout the week the shifts slowly start to get better, but every once in awhile (under harder accelerations) it would still shift hard. At times, the shifts were so hard that if I had a bottle of water in the cup holder it would fall out. I realize now that something was/is wrong. I called Eric and left a message both on his cell and at the shop, but I figured he is away for the holiday weekend.

Thanks again for the help Mike:cool:

Yes, Eric is out of town. Even he takes time off!):h

This probably has nothing to do with what's going on with your tranny, but I got a p0700 code on the first drive after my install. The tranny was doing all kinds of weird stuff, including shifting violently. The cure was to reseat the connections on the harness plug-in on the drivers side of the tranny. Problem went away immediately.

I also had a simliar problem but there was some junk in convertor that came out and plugged lube valve.

Just got back in town. I'll be at the shop tomarrow and we can discuss any of this.

Eric,

Give me a call in the morning or whenever you get a chance, 609-743-0595

I hope you don't get the wrong impression by reading this, after I went back and re-read it it seems that I am pissed at you, I am by no means, I understand things happen and that it will be fixed. Thanks again.

If you were pissed you would have changed your sig by now...LOL

I recognize that tel number, I seen it on my cell this morning and listened to the message...gotta love Nextel.. I couldnt even make out who it was, let alone what they ( you ) wanted. hehehhe

hahaha, who would have thought, a problem with nextel??? :D gotta have it for work though

update???

update???

Just so everything is clear the post gives an impression that this quote"Sun Coast V" unquote is a week old, NOT TRUE ! This trans is a used trans, originally built in 06/06/03. We refreshed the clutches when the customer traded trucks in 05. The trans was removed when the customer traded the 05 for an 06 by someone else. Whats happened with the trans after that, I do not know. I regret that the gentleman has had a problem, but it seems his post cast a negative light where it should not.
Smoop

I've talked to 00Sierra on the phone, issue is being resolved. Its unsure what happened exactly until it can be diagnosed further.

Just to add to what Smoop said, it was purchased as a used unit and 00Sierra was aware of that when he purchased it from me.

so now we know......the rest of the story;)

And I hope that no one is upset with a slight title change.;)

p0700 code is just the code that means Trans is pissed. Its not a specific code detailing of a problem.

As Eric posted everything is being taken care of. I will be going to his shop later in the week to have it fixed/diagnosed. I was aware that it was used when I bought it, and thinking back I should have been a little more clear, but I posted it about 20 min. after it happened and I was quite upset at that point.

I by no means intended for this post to be badmouthing Eric or Suncoast.

It's all Good. Good Luck, and let us know how it turns out.:)

will do, now I'm having the fun time of finding a trailer to get it out there on:D

hahaha, who would have thought, a problem with nextel??? :D gotta have it for work though

You mean SPRINT right?:rolleyes:

He made a mistake and wasnt clear with his post. Who it realy hurt was himself becasue he wasnt providing the info needed for others to help him. Everyone knows that its not a new SC that let go in a week so there is no missinformation out there. No need to bust his balls.

Leave it to Eric to fix it. He sold it to you so its up to him to make it right if its a trans issue with what he sold ya. If its an install issue then who ever did the install needs to make it right. If your sure its not an install issue or an issue in the truck(wiring etc) then sending just the trans could be an option? Save you from having to ship the truck. Maybe Rick or one of the other hauling guys could make some room for you either way you go if its the whole truck or just the trans? Post up in the were are we thread in the uses forum.

Also on a side and unrelated note. Have you talked with suncoast and seen what it would cost or if they would be willing to take your used trans and "refresh it" or fix whats wrong and you get something back from them? Joe has always taken good care of me when he was fixing F ups even when they were casued by me ):h

Has anyone been able take a guess on if its a truck or a trans problem or if its an install problem?

As far as the install I did it in my old shop. I am fairly certian it is the shaft that broke inside. I am actually towing my truck out to Erics with my friends truck, we are going to fix/diagnois my truck and install a trans in my friends truck, take care of everything at once, plus I will be getting away for a few days. I'm also getting a set of lift pumps while I'm there.

I have not spoke with Suncoast, only reason I didn't call them was because I figured I would just go out to Erics and have him do both trucks

Wow an SC V, I thought blowing my SC IV was major, were you launching at high boost? I did once, and that is how I fried mine.

How do you launch at high boost???

so now we know......the rest of the story;)
I think that there is more to this story...:cool:

How do you launch at high boost???

4X4, stand on the brakes, then stand on the go pedal, let off the brakes when the rpm gets close to 3000 :eek:

4X4, stand on the brakes, then stand on the go pedal, let off the brakes when the rpm gets close to 3000 :eek:

And boy was it scary, the tranny was fried launching at 3k RPM. The converter was already bad, otherwise I wouldn't be able to do it.

Everything is fixed and running better than ever. Ended up having a major problem, but Eric had it out and fixed in a day. Thanks again for all the help!!!!

What was the major problem?

Please Explain.;)

Did it have something to do do with power issues, launch issues, tuning issues?

Thanks for info!

What went wrong internally

Yeah, that would suck. Mine was just the converter, and the planets. The clutches were fine, but they went ahead and replaced them anyway, just in casse there were shards of metal from the converter. They also replaced the cooler for that reason.

Clutches and converter were fine, it was actually the shaft and gears that went. I'm sure that Eric can explain it better than me. He also has some pictures that I'm sure he will post up.

I am not at liberty to post them but I can tell you I have never seen carnage that bad. ( almost ) It does take second place to that 2wd truck that destroyed his Alli on the launch, but not by much.

Any reasons why it happened?

Thats what Eric said, it was bad:eek: .

I don't have the pics to post, forgot to bring my camera, but I hope Eric will post them. Main reason I want them is because my friend who helped me put the trans wants to see them.

What gives?

How Much Horse Power and Torque?

Is the power what killed this thing? or was it damaged before the install?

Was it the "one in a million"?

How many miles were on this tranny?

Power had nothing to do with the failure. It was a tie up. Thats the only thing that can even remotely possibly cause this. Clutches were pristine.

I drove the truck the trans come out of with it in. He is a member here that owned this trans before. Trans was fine in previous truck.

Any idea what could have caused the tie up?

Absolutely.

The cause of the problem was found and corrected.

Well, i definately know more now.):h I'll try to make sure mine doesn't do that.;)

Keep it to yourself then.:D

Keep it to yourself then.:D

If the information is kept a secret, then how can something like this be avoided by the rest of us? I thought this was a place to learn about what to do, or not to do.

As for the pictures, thanks for posting them Eric. OMG fell out of my mouth when I saw the first one scroll into view.
Goes to show that a bullet proof set of part can grenade.

It had nothing to do with power issues. I was running Mcrats race tune I got with my EFI live, great tune, but with no pumps/shims, etc I doubt I was making that much.

I have not seen that much Damage to a unit since a guy hit the transbrake button trying to go into second at the track.

why keep the secret to yourself then????what gives im missing something....im glad ive learned something from this thread:rolleyes:

Massive Tie up. That is the cause of failure. Happy?

Three clutches on at once. Its no different then when we strip the splines on the hub. This one just was a little more extreme. As we push trannies further, we find other issues.

why keep the secret to yourself then????what gives im missing something....im glad ive learned something from this thread:rolleyes:

Suppose Mike, Eric, or someone else took the time to explain exactly what happened here. Would you really be better off?
There was a snafu, parts broke, snafu fixed, transmission is fixed...Life is good..

Have a coke and a smile...:D

is this the result of tranny tunning gone bad, using efi?

My comment to Rick was in fun only as was his preceding mine. Tuning was not the cause of this. In my obsevation a part failed in the Alli and when it got hammered with some big power the result was big damage. I don't see anyone at fault here.

Yeah, sorry we side tracked the thread. I have given myself a warning for it.):h

Mike or Eric, is it safe to say that it would be virtually impossible for this to happen to anyone else's tranny?

Yeah, sorry we side tracked the thread. I have given myself a warning for it.):h

See, you guys start messin aroud and make everyone mad.:badidea: :lol:

is this the result of tranny tunning gone bad, using efi?

Never touched the TCM with EFI.

I will say, that now that this problem is taken care of I couldn't be happier. The truck runs and shifts great. I hope to get a chance this week to make a little adjustments with the tune and get to the track. Thanks again for all the help:)

Maybe that was the problem that you DIDN'T touch the TCM with EFI live, if you did, this wouldn't have happened ;)

I shouldn't say that I didn't touch it, all I did was reset the TAPS with it.

I have a quick question, is your transmission acting at all like it is relearning your driving style, because when I got mine rebuilt, it did that.

Since I got home the truck is running great, trans has learned my driving and I love the way it shifts, real smooth. The minute we pulled out of the shop to test drive it I knew it was fixed, the thing never felt so good.

Did you do a burnout living the shop then? :D

glad your happy with the tranny..................hats off to eric for stepping up and making it right...............

For clarification that is what I do all the time (side track the thread) sorry, just means that I will try to stay on "thread"....

:D Glad its fixed. Looks like Eric lived up to his rep. Note to self, never let 00sierra drive my truck.:D

Hey Mike... how about letting us all know what caused it?? I'd like to also make sure my SC IV never does anything like that...
