Noob here... I have a 1994 2500 2wd donor truck w/ a 5.7tbi and a 4L80e trans. I'm putting the motor in my Land Cruiser wagon FJ60. I have a 700r4 ready to bolt in(even has the AA tailshaft for the 203) and I am also using a 203 range box infront of my t-case as a doubler. Here's the question...Has anyone put a 203 behind a 2wd 4l80e? Should I stick w/ the built 700r4 or try to get the 4l80(already attached to the 5.7) to work? Keep in mind this is a conversion, so wiring, mounts, crossmenbers,etc are all going to be modded. Thanks!
