transmission planning for a CJ7

Rusted · 2005-05-18T17:55:46+00:00

The old T5 in the 83 CJ7 with 210K miles is getting a little old, just like the rest of the jeep. It is still working ok, so I am not in a rush, but I would like to start looking for parts and getting ready to replace it. I plan on keeping the Jeep street legal, and street drivable, but want to eventually get up to 35" ish tires, and more off-road capable.So to get started I want a transmission that is strong, and has a crawler gear options. Any opinions or experience with a T18, SM465 or NV4500? I see lots of T18's in jeeps, but not as many SM465. They both should be pretty common, and fairly comparable. Is there a reason we see more T18's in CJ's? Any issues with a SM465 that you would not have with a T18? I figure if I keep an eye out for parts now, and save for the adapters and possibly a rebuild I figure I can do this swap for pretty cheap. I have the D300 t-case, and a 258 engine if that matters with any of your comments. Thanks for any advice while I get idea.

I see all the sites list the AX15 as a medium duty, which is what I put in my 81 cj, 258 and D 300.
