just finished my lq9, btr stage 4 cam and trick flow as cast heads, ill be running a 3600 rpm stall now all im waiting on is to make a decision on a tranny. Truck is 4x4 and currently sits on 33s but will be going back on the ground here shortly, had planned on going with a stage 5 4l60e from rpm or flt but now im second guessing myself for a 4l80e. maybe i havent done enough digging but i havent found a decent 4wd 60e to 80e swap thread. ive found plenty on 2wd swaps but i know there is more too it such as the tcase shaft. Any input, comments, suggestions and or F U`s would be greatly appreciated.

 

Its basically the same as 2wd, and there are several 4wd swap threads. The big thing is the input gear needed for the tcase. Pretty easy to find for the 4wd tcases, the AWD ones not so much. Rear dshaft needs to be shortened 1 5/16" and trans crossmember moves back 2.5" I think.

 

Do the 80e, you'll thank yourself later
Check this link out its pretty in depth for the 4wd 80e swap
