My TH400 is in good condition. The Highway is killing me though. I just cant take the noise. Anyway, heres my specs: 6.2L / TH400 / NP208 with 4.10's. Is there a place I can order a rebuilt 700r4 to go into my diesel without the BS of swapping shafts, and getting adapters and all that crap. I just wanna REMOVE TH400 and INSERT 700R4. If I have to move crossmember back or forward thats no big deal. I dont want to have to modify much. Will I need longer driveshafts, shorter driveshafts ? if so, can I get them off another truck with a 6.2 and 700R4. ALSO were 700R4's ever factory Trannys on a 6.2 and if so, what trucks were they mostly found on. I want this as simple as possible.
