Tranny is already slipping

Duramax09 · 06-28-2009, 09:55 PM

I just recently bought my dmax about a month ago and it had about 2,200 miles on it when I deleted the dpf on it and installed the edge. I now have 3,000 miles on it and the tranny is already slipping which is very disappointing to me especially since I don't drive it like I stole it lol. I never ran the edge over level 3 which is recommended for a stock truck. Any suggestions on what I should do bc I might put the transgo jr. in it but Im just worried that it might be to late. Any help is appreciated thanks.

What are the codes?

when is it slipping? what speeds and gears? haha and hondarider, those quotes are hilarious, haha

There is no code. it just really feels noticeable during the shifts.

It's probably the tuner de-fueling between shifts. You will notice a lag between gears as you shift through them.

Yeah but it never did it whenever I first put the programmer in

Will they always throw a code on a slip?

it might be the allison learning the higher power level. If you have no codes, it might not be slipping. How many miles? have you changed the tranny spin-on? how many miles on the fuel filter?

might just be relearning the increased HP, should throw a code if its slipping.

IIRC, allisons will have to slip 6% in order to limp and set a P07XX code. Yes, it can slip without throwing a code, but your doing damage.
Turn the edge down.
