Auto transmission to manual transmisson swap.

Hey guys,

First off I would like to say thanks for all the great information on this thread! Although I am a new member I have been searching this thread for months.

Anyway, I have a 1994 Jeep Wrangler YJ 2.5L with an auto transmission. The engine and transmission are both getting weak and I need to be planning for the future. I have found a guy selling a 1991 Jeep Wrangler YJ 2.5L engine, transmission, and transfer case online.

If I made the swap I would change everything, engine, transmission, and transfer case. My question is what will I be looking into if I did make the swap like this? Should everything in theory bolt up? What would I need to look into with switching an auto to a manual? Thanks in advance for all your help!

First off - WELCOME from the shadows into the light.

Second, what transmission is bolted up to the 2.5 for sale? The AX-5? If so, a word of caution, 5th gear in the AX-5 is held in place with a C-clip that has a tendency to crack allowing 5th gear to slide away giving you a 4 speed transmission. Also, the AX-5 isn't the strongest trans out there. If it's an AX-15, you're golden.

As for the swap, you're going to need to get a new steering column. One without the shifter on it. I believe, but I'm sure those with more knowledge will chime in, there's some wiring that has to get changed around as well. I thought about going down this road with my rig and was advised that it was more of a job than it was worth. Not sure how valid the statement was.

It depends if the ax-5 that comes with it is in good shape. You will need the clutch hydraulics, as well. It will be an internal slave, which is lame. A 4.0 swap would be worth the effort.

Thanks for the replies guys. I think I am going to hold off on this purchase. I'm just gonna run my current set up until it quits and go from there.
