Re: What transmission should I use?????
They are all good tranies, it just depends on your usage and general requirements. For specific gearing specs try searching on Yahoo or something. Generally though the th400 is much stronger than the th350, but it is longer. Neither of them have the overdrive that the 700r4 has, but then you'll have to work out a lock up for the torque converter (since you won't have the ecm to control it, there are kits available to do this, most hot-rod shops can get them for you) Running a 700r4 without locking the converter in O.D. tends over heat the fluid and destroy things.

Next problem is adapters... Jeep originally ran a th400 behind the 304 in the late '70's if you can get one of those you'll only have to adapt it to your t-case, otherwise you'll need bellhousing and t-case adapters. Finally with any of these swaps you'll more than likely need to change driveshaft lengths. Any qualified driveline shop can do this for you for around $50-$100 per shaft.
Personally I love my 700r4, but they are much more expensive than the 350 or 400's. [img]images/icons/frown.gif[/img]
That probably didn't answer your questions, but it might give you some idea of where to go, otherwise try searching on here, I'm sure this topic has been covered before. [img]images/icons/cool.gif[/img]
