I have a 1968 cj5 with the dauntless engine with a Dana 18 transfer case and I believe either an T86 or a swap T90 parts inside the T86. Not sure. Will this T90 transmission direct fit to the bell housing the the V6 dauntless and the T90. I imagine I need to buy a new drive shaft. Trying to replace entire transmission while rebuilding the clutch in a month. Thanks

I have a 1969 Jeep Willys with the V6 Dauntless. Ths listing for this doesn't state that it is for my year. Please clarify.

Willys Jeep Parts Tech:
As long as you have the T90 transmission in your and not a T86 then yes, it would be the one for you.

I guy I know is selling me a T-90 out of his 62 Willys truck, along with the T-Case and axles. would something like that swap into a 56 Cj-5?

I have a 1971 CJ5 with the Buick V6 engine as well. I believe the transmission is a T14 but i haven't checked the tag on it yet. The back of the transmission case is apparently cracked as the previous owner tried to JB Weld it. It just leaks fluid real bad around the JB Weld. Will the internals of a T14 or a T86 fit into the T90 case?

Willys Jeep Parts Tech:
If if a 6-226 it should.
Willys Jeep Parts Tech:
Email to help out on this. You most likely have a T86 or T14/15
Willys Jeep Parts Tech:
No, the internals will no interchange. We can offer you rebuilt transmissions for what you have though. Please call us toll free. Ask for Mike M.

Will this fit into a 1970 CJ5 with a transfer case with the 226 V-6 engine? The description says 54 willys truck and station wagon.
