Question T-18 and Dana 300

I have a CJ-7 w/ a T-18 transmission and AMC 360. It's a '79, so it also comes with the Dana 20 transfer case and I am thinking of swapping it with the Dana 300 and changing the low gear so that I can the 4:1 ratio. Is it possible to connect a T-18, Dana 300 and AMC 360 without a lot of effort and cost?

You say you already have the tranny and motor together, so all you need is a $505.42 adapter from Advanced Adapters. There are two different adapters though. If your T-18 was swapped in it could be a Ford or A Jeep tranny. Jeep tranny adapter part number is 50-7502, Ford tranny is part # is 50-7500.

Hope I helped.

T18/D300

If you are doing the 4:1 conversion anyway, stick with the D20. It will work just as well, and you will save $500.

This isn't much technical help, just testamonial. If you want to go rock crawlin' you won't regret making the swap to D300. I just bought an '81 CJ-8 with a 360 V-8 EFI T-18 and D300. Granny gear is 6:32. The first time I went rock crawlin' I was in heaven. The Jeep would go anywhere. I never had as much fun wheelin' I'm going out again in about two weeks. I can't wait. Oh, did I mention ARB lockers front and rear? They helped some, too. Good luck and rocky trails to ya.

Hi Glovematt,
a good option and pretty cheap is for you to find a Dana 300 out of a 1980 Scout with a standard transmission (note that it MUST be a 1980 with a stick!). It will bolt on directly to your tranny. Now the only thing is that you have to find out if you have a ford T18 or a Jeep T18 (from what I know the easiest way to find out is to see where your reverse is ...if it is all the way to the right and back is a jeep T18).

Sorry but that's not a good way to see what it's from. Jeep T18 older than mid-78 have reverse far right and up. Mid-78 and newer have reverse far right and down. It depends on the year, not what it came in.

My T-18 reverse is a right and down and is from a Ford, so there has to be some other way to tell them apart. Advance Adapters would know for sure. 1-800-350-2223

If you can see the front of the transmission the bolt pattern where the tranny bolts to the flywheel is a dead giveaway. On a Ford the bottom two holes are the same distance away from the top two holes. On the Jeep version the lower hole on the driver side is closer to the top hole than the lower hole on the passenger side. It is an easily seen difference. Anybody wanting info on the T18 or any other component having to do with a Jeep really should check out www.jeeptech.com . There's a wealth of into there including things that distinguish one part from another.
