Hi,
Im planning on chaning my powerplant in the HMMWV to the turbo engine, 4l80E transmission and 242 transfer case. I see they sell cutouts like this
I know I need :
TCM, going with an aftermarket so I dont need to change the wiring harness
A2 Driveshafts
New 4speed shifter
Maybe some new fittings to trans cooler
And other stuff like new doghouse
It is going into a M998 1989 model
I have read a little on this post http://g503.com/forums/viewtopic.php?f=63&t=221765&p=1305053&hilit=4l80#p1305053
