4l60e vs. 4l80e

4l60e vs. 4l80e

Postby buckassassin [OP] » Jun 01 2011, 3:37am

i was wondering if i can take my 4l60e out because it has a overhaul shift kit in it and put a stock 4l80e in? the reason is because i have horses and do alot of hauling and the shift kit shifts so hard it sounds like the rearend is falling out of the truck... it also has a 4.8l.. will the 4l80e bolt right up?

Is there a way to soften the shift kit up? what kind is it? does it have settings?

From what ive seen a 4l80e will not bolt up without cross member mods,

Heres a nice guide/writeup i found if your interested,

i dnt think there are any way to adjust anything on the transmission. It is a 4L60E with a TCI overhaul shift kit. What i was told about the kit is that it is for hauling overweight.. Thats all i know about it. Thank you for the website and the info on the 4L80E

Are you running a programer with any trans tuning? Most shift kits say not to run trans tuning with shift kits and/or uprgaded servos. If you have tuning unistall it and see if it drives more to your liking and if so turn off the trans tuning if possible or pick up another tuner like Diablo's Predator that gives you the option. Hope you get it figured out.
