Default drivetrain swap is it worth the headache

I have a 91 auto Cherokee that the motor died on. So I went looking for another. Found a 94 manual lifted low miles sye and heavier axles. The problem the entire floor is rusted out. Thinking about swapping suspention and drive train to my 91. How big of a pain to change an auto to a manual?

Just pull the tranny out from yours and put it between the good engine and t case. No need to convert unless you wanted a 5 speed.

Honestly a rusted out floor isn't a complete death sentence if you have the time and patience to do the work putting new floor pans in. I bought all of my stuff for about $300 and when I get my second xj I'm going to put my current one under the scalpel and get it done in a weekend or 2. Plus if you do the swap in of the engine on to yours and just run it for a while and if your engine is salvageable I would use it as and excuse to make a 4.6 stroker to put in that big rig and then you can start building the one with the better axles and sye to be your weekend trail warrior.

Well thanks for the input but the deals off for the 94. I had told the seller is think ad out it. She just sent me somenasty messages on face bbook over the whole deal. Don't want to do buisness with someone like that. So the search is on.

I do prefer manuals but doesn't matter to much. It was my daily driver/huntin rig. Also I think the motors probably screwed. I was just under full on oil the day before and now it shows over a quart over full. Was told by our mechanic at work I probably cracked the block.

Drain your oil and check for coolant. You could have just misread it. But you'll know for sure by draining it.

I am doubting your mechanic's "shoot from the hip" response. Some further investigation is worthwhile.

I'm glad that guy doesn't work on my XJ, questionable skills to say the least.

Good catch. I automatically read that as cracked head. Highly unlikely you cracked the cast iron block...

He was just making a guess from what I told him hes never looked at it. When I pull it I'm going to tear it downjust to see what happened.

I was considering a Chevy v8 swap since I have one laying around but from what I've read its a bad idea with the auto tranny

why not diag the motor that's in it. the 4.0L is a very, very stout motor and its hard as hell to kill them.

This is the second time the motor went. I rebuilt it ran fine just had some lifter noise. I just need to get it going quick I sold my other jeep a couple weeks ago. So I need a vehicle and figured just do a motor swap or find another and build one out of them since my body is really rough

V8 swap is about 9000 times harder than fixing a 4.0L... what are you breaking? Head gaskets? Buddy been filling your crankcase when you're not looking?
