The
T-5 you have is light duty.
Your signature says "im gonna drive & break the hell out of it and replace everything with better parts". Well nows the time to live up to your own promise. Trash your
T-5 and put in a
T-18 Transmission .
I was in the same boat as you I had an '82
CJ7 and when the 65 pound
T-5 gave out I put in a
AMC 150 pound
T-18 .
There are two types of T18s. One for Jeeps and one for Fords. The Jeep
T-18 is hard to find. Do what I did and get a Ford
T-18 . This will bolt right up to your engine. You will have to drill and tap new holes in the bellhousing for the tranny to bolt up. For the clutch I used a jeep pressure plate and a ford friction plate.
Now to bolt it up to your
Dana 300 TCase. This won't be so easy. One option would be to get a Ford TCase with your tranny. Another option, and the one I went with, was to replace the
T-18 Main (output) shaft with one from a company such as Advanced Adapters. The
T-18 is relatively easy to rebuild.
You will want to get a
T-18 with a granny low first. Not all had this. You will give up your
Overdrive for this low gearing. What gearing do you have in your axles?
