can you change power levels on the fly without damaging the Allison? or you have to let the Allison learn for a while after changing powerlevels (up/down)?

Do a search...


You'll find that you should probably take it easy (levels 1 and 2) in the beginning until the Ally learns to handle the added HP and torque.... then set it to no more than level 4 with a stock tranny.


Keep it on the same power level (whichever you choose). Alot has been said on this board that the Ally doesn't like it when the power levels move around.....Edited by: Blinky

I was kinda afraid of that.. thx for the info.

What about flipping between the t/h mode and regular drive once the juice in installed? I plan on running in 3 in the regular tranny mode, and 1 or 2 in T/H... Will that change screw with the shifts, or once the juice is installed, should one drive around in each mode to get the tranny to learn in each?

Marc,


I take it you don't have the Attitude? If so you just set it and forget it, but if you tow, then you have to change the level with the Attitude (shifting between T/H and out does nothing if you have the Attitude).


You can change on the fly, but results may vary. . . Are you talking you're racing a guy in level 3 and he starts to pull on you, so you want to shift to level 4 or 5 while WOT? If so, I wouldn't do it to my truck, but I'm sure plenty of people have done it without any problems.


Dennis

Dennis is right about the power levels not changing between T/H and normal when the Attitude is installed.


When you change power levels, it does take some time for the Ally to re-learn, but it handles going down in power levels much better than it handles going up.


Edge says it takes about 200 miles of around town stop and go driving for the trans to fully adapt, so doing it for just a bit isn't going to accomplish much. As Blinky said, pick a level and leave it there, if you need to go down for towing, you won't notice much change in shifting behavior, but if you're there for a while and then go back up, you'll notice the Ally being a bit out of step for re-learn...http://www.dieselplace.com/forum/smileys/Ermm.gif

I hadn't realized that with the Attitude it was only changed via the Attitude. I don't have anything...yet. I'm still in research mode. http://www.dieselplace.com/forum/smileys/Big Smile.gif\

I was talking about when I hook up the trailer, I know I can't tow in level 3 (which is as high as I'll probably go. Yeah right.), so I'll need to back it off to 2 or 1. Didn't know if that would mess with the shifts.

Marc

Another thing to think about. I only run in level 3 because my tranny is stock right now. When I tow, I will drop it down to level 1. There will be a bigger difference in how it shifts between changing one level and changing four levels (i.e., going from 3 to 2 vs. going from level 5 to 1) on how it shifts. IIRC, the guys that have the most noticeable effects when changing levels on the shift quality are the guys that shift several levels at once. I personally didn't notice that much difference from the stock feel. I started on level 1 ran it that way for a week or two, then went to level 2, same thing and have now been on level 3 for a while. I love it. I am anxious to try level 4 and 5, but I'm going to do my best to wait until the tranny is no longer stock, and at least until I move again and won't have to worry about towing the BAT around (Big-A$$ trailer) for a while. After that, game on!


If you're unsure about the Attitude, just install the monitor but don't install the EGT probe. You will lose some functionality, but if you want to return it, you won't have to worry about a hole in the manifold. Once again, though, once you install it, I think you'll like it, and it will in to stay.


Other concerns are warranty work. It is easily removeable in minutes, even with the Attitude, and you can explain the probe by exclaiming that you are installing gauges and haven't finished the interior part yet. . .


Dennis

Ok.. so I really can't change powerlevels on the fly like I could in my Dodge. I'm ok with that but that raises another question. It there a programer that might be as good or better than the power of an Edge box on say level 3 (or whatever level will not kill my stock tranny).

No, that's not what we said...http://www.dieselplace.com/forum/smileys/Embarrased.gif


All we said is that we didn't think it's a good idea to try it while you're getting on it, but you can if you want.


The other part is that if you only have the Juice, switching to Tow/Haul mode automatically sets the power level to what ever you pre-set for that mode. That function is disabled with the Attitude installed because you can change power levels with the touch of a button anytime you want, assuming of course the power is on...http://www.dieselplace.com/forum/smileys/Cool.gif

http://dieselplace.com/forum/smileys/Big%20Smile.gif I would never try that any way.. but if its a good idea to drive a short distance for the allison to relearn up or down. That just makes me wonder if maybe a programer is the ticket. Still undecided, just gather info.

what do the EGTS look like on Juice level 3

Okay, I'm obviously not getting through here so I'll yield the floor to someone else...http://www.dieselplace.com/forum/smileys/Confused.gif

Every time the allison makes a shift up down left or right it looks at a ton of different variables to see if it can make the next shift better. when I say next shift I mean the same type of shift, same gear same throttle position ect not the next actual shift. It decides "oh I need to shift a bit faster cuz it slipped just a tad or I can scale it back a bit so I retain that smooth soft cady like shift" It will take a few times to continue to fine tune things and get em dead on nuts. When its used to needing to shift in a certian way and then you bump up the power it is used to shifting with the lower power and its easier to overpower it durring the shift. Make sense so far? It dosnt matter what you do to increase power or decrease it the allison is still trying to make the perfect shift, just enough to get the job done without excess slipping but not enough to make it harsh. You could drive for 3 years and never train the allison or you could train it in 3 minutes. All that matters is # of shifts and making the shifts under all the different conditions. Most say if you want to "train" your allison to go out and make a bunch of runs from a stop through all the gears. Make 5 or so from 1/4 throttle then go on to 1/2 throttle then on to 3/4 and then to WOT and do your downshifts too. Or just drive it and it will get with the program eventually. That make sense? any Q's?


Dont know about the egt question since i have an LB7 and exhaust


Edit: How do you know if your ally is trained? If all of the shifts up down are all nice and crisp and stock feeling.Edited by: ratlover

ratlover;


you need to write a how too booklet on the j/a. all the little tricks and how to's about it. it would be a best seller!!!!!





p.s. i would buy one

the world would be a scarry place if I wrote a book and people started reading it much less following my advice. I'm betting Mike L. would have a month long waiting list though and Eric would never sleep trying to keep guys trucks on the road. I'd become rich though, my stock in goodyear would go through the roofhttp://www.dieselplace.com/forum/smileys/HiHi.gif


I need to talk to Nick about becoming a vendor. Rat's guide to destruction is now for sale. Just need to talk with a lawyer to get the right disclaimer and clear myself from any liability. I dont think "I'm not going to be responsible for trashing your truck, your death, dismemberment, incarceration or divorce in the process of following any of my advice. Smoke ricers/tires/clutches at your own risk." will hold up in courthttp://www.dieselplace.com/forum/smileys/Confused.gif

I think there's already a book that talks about all this stuff, it's the owner's manual. Seriously, though, the manual is an excellent reference on how the Juice/Attitude works. Pretty much any question you have that isn't a problem is answered fairly clearly in it.
