Change from Automatic to Manual

I'm trying to not get to psyched but I finally found a jeep I can afford to start with. The only fall back is it's an automatic, but the transmission is shot and needs to be replaced anyway. How hard is it to change one of these from an automatic to a manual?

I may have worded that poorly, what I meant was how much hacking and cutting should I expect if any. My assumption would be it would mostly be a bolt in change with the addition of the parts needed for the change. What I'm wondering is will it require any changes to the frame, major cutting on the tub?

The easiest way to do it is find a parts jeep. That is all rotted out . All your parts are there for the exchange. No changes to the frame. The only thing is that the transmission hump needs to be cut out or swapped from another jeep.

I assumed it would be something like that, thanks for the heads up. Now I can begin obsessing.

Another way to do this, if it's a 1980 to '86 with a TF999, plenty of people decide to do the reverse. Be patient, find someone who wants an automatic and trade parts. That way both of you get everything you need.

Are you sure about this ? I had an 83 CJ7, 258/T5 and now have an 85 CJ7, 258/auto. I had both for a short time and did comparisons. I never noticed that. I think the shifter floor plate cover is all that needs to be swapped. The automatic has column shift and only a floor shifter for four wheel drive selection. A bolt in replacement.

I do not have the manual tranny, but I have the brake/clutch pedal assembly, steering column, tranny tunnel cover, and assorted other parts if you'd be interested in a trade. What year CJ do you have?

As replied, the most cost efficient method is to find a similar year CJ with the manual transmission you want. 76-79 there were only two: T150 and T18 with the Dana 20 transfer case. 80-86 there were: SR4/T4, T5, and T176 options all with the Dana 300 transfer case.

Biggest PITA? Probably installing the hanging pedal assembly which will require removal of the steering column, and a bunch of under dash contortions.

Personally, I would do some soul searching and determine what the CJ purpose is. Daily driving, or commuting in stop and go traffic, would certainly make that automatic an asset.

`I actually haven't bought one yet. But I have a few I'm looking at over the next week and they all seem to be automatics. I absolutely hate automatic transmissions in just about any vehicle. If it was between an automatic or no jeep I'd just have to live with the auto, I was just curious how hard it would be to swap out later.

Take your time looking and start out with the vehicle configuration you really want in the first place. You will be much happier.
