4l80e swap into 07 avalanche seems to have lost power low end99747
I swapped a 4l80e into my 07 avalanche. it seems slow and sluggish changed a few things but wanted to get some opinions before I screwed something up. thanks
Swapped 4l80e into my 07 avalanche. Trying to address some shift points and such. Cant log trans shift mode. It gives me unknown:40 on the scanner. any ideas if Ive missed any thing? This is my tune...
Is it better to buy 08 express t42 tcm or reflash current t42?
Seeking the same knowlege got all the install done today now wiring and programming.
Will a 2005 4l80e tune work in a 2007 new body style computer? Is the a difference between 2005 and 2008 4l80e transmission tunes? Thanks for helping
it went into closed loop after it warmed up towards the end of the file
