Awesome write up!!! I was wondering where everyone is getting the 4L80E tune or calibration from?

howard quick

With EFILive you can perform your own segment swaps, so all you need is a calibration file from a vehicle running the operating system as your own...but using the 4L80E and you can transfer the trans parameters and diagnostics to your own cal file.

Update for 4l80 factory tranny lines for non hd frames.

these lines will fit the factory cooler.

researched the 3/4 ton avs and subs to find them. They come wth 4l80 and dont have taller frames or body lifts.

Supersub,

are you saying those are a direct bolt in for 1500s? If so, that is great news, because I really wasn't all too interested in not having hard lines to my trans!
