well I swapped in the 4r70w
swap was stupid easy, by far the easiest trans swap i've ever done in my life, i simply unplugged the 4r100 trans harness and plugged in the 4r70w trans harness, ripped out the 4r100 and tossed the 4r70w in, flipped the 4r70w trans mount bracket backwards and bolted up my original 4r100 cross member, i cut the bigger 4r100 cooler lines and hosed them into the 4r70w cooler ends, last i made a few tune changes, fired her up put a couple gallons of fluid in her and drove away, start to finish only took 6 hours all said and done I guess pulling the transmission 7 times in the past couple months really makes the process so much easier
Truck has been running flawless, I will be locating a 4r70w cross member for the trans though so it can be mounted correctly, my make shift mount has no give to it at all, the guy in mississippi has the cross and he won't be using it, i'll probably go snatch it from him if i can't find another local
