The
T-18 was found in Scouts but avoid those. You will have trouble adapting both ends to fit in your jeep.
T-18 was also in Ford trucks from '65 to '91 Those would be the best
T-18 swaps becouse they would bolt up to your bellhousing after drilling and tapping 4 holes. You would need an adapter for the
Dana 300
The
T-18 was also found in lots of Jeeps from '66 to '84 but they were not standardized. Many Jeep T18s would be hard to fit into your CJ. If the Jeep
T-18 came out of a full sized jeep it may have a big adapter on the front like the pic below. Then you need to remove the adapter and install a shorter input shaft. You would also need an adapter for the TCase. Almost all Jeep
T-18 transmissions came with a
Dana 20 TCase. A Jeep
T-18 mated to a
Dana 300 is a very rare find.
CJs from the '70s often came with a
T-18 . Those always had a
Dana 20 Tcase. If you fine one of those try to get everything from the bellhousing to
Dana 20 . You wouldn't be able to reuse your driveshfts but otherwise that would be an easy swap.
The
T-18 is a heavy duty truck
Transmission and it shifts as such.

The
T-176 would be an easy swap. The only issue is you would need to modify the lengths of the driveshafts. It's a good, strong
Transmission . They were found in some CJs from the '80s if the buyer designated the heavy duty
Transmission .
