I have a 82 CJ7 with a 4.2 and a 4spd T3-51-097-901 transmission, I bought a 4.0 from a 96 Cherokee that had a automatic transmission. Can I use my trans with the 4.0? And how do I get them to match up if I can?

If I remember right the 4.2 & 4.0 blocks were very close. I think the bell housing's should interchange. I may be wrong.

What is the final result. If its a fuel injected 4.0 connected to the T3 you will need to get an alternative crankshaft position sensor location.
Its a direct bolt in if you are planning on running an HEI distributer and a carb. The AX-15 bellhousing has a hole for the CPS to bolt in.

No such transmission. Those numbers should be "13-51-097-901".

Further, those numbers occur on BOTH 4-speed and 5-speed transmission top covers, both 2wd and 4x4, many gear ratios, and from the early 80s through 2002, so they are useless for identifying a transmission.
