Re: [AMC-List] 79 CJ7 Transmission ID ??

[msproviero@xxxxxxxxxxx]

A T-4 would not have been available until after 1980.  Its a T-18a 4-speed, which would be the wide-ratio model in a CJ, and should have a Dana 20 behind it.  IMHO, its the best factory configuration you can start with if you want a CJ for a toy.  If his 79 has the leftover-from-78 big discs and 11" drums, even better.

There is an unconfirmed belief that T-18's were not available from the factory behind 304's and were 6-cylinder transmissions only, but I have run into a few people that swear that they have owned their 304/T-18 CJ's ever since they rolled off the lot (but never provided me with the VIN).  A T-150 to T-18 swap can be done with 100% factory parts, which would make the vehicle appear that it had always been that way from the factory.  If he wants to know if it is the factory transmission, decoding the VIN will give him the answer.

Here's its page on the Novak Knowledge base site, which is a great reference tool for IDing transmissions.
