Got a 90 Jimmy w/700R4 and 241, just got deal on TH400. What all am I going to have to do to get this to work. I know I will need to move the crossmember, will I need to get an adapter for the mate to the 241 or will I need to get a diff t-case? And The 700 (4L-60) I have is not the Electric one but I someone told me it still has something controlled by the computer. Plus Im bolting this beast up to a 350 turned 383. Don't you buy no ugly truck!
