Looking for info about how difficult a tranny rebuild is for the backyard type mechanic. I would be looking to replace clutches, bands, input shaft, band struts, etc.

I haven't rebuilt a automatic tranny, but have done a manual. My one suggestion if you should try, is to set up a movie camera to film the disassembly, it will help getting things back where they belong. I learned this from my father-in-law when taking apart computers in the early 80's.

I have not rebuilt the stock tranny but I did install a Shift kit on the valve body. That in itself was a fairly involved project. I think it would be possible if you had the right directions and space to accomplish the task. One thing I have is a fairly decent garage. 26x28. A parts cleaning location I am sure would also help if you do not have one. I had 1/2 my garage covereed with valve body parts while I had it open and I am sure you would need even more space if you open the transmission up.

I was able to watch them rebuild the tranny in my other truck (DTT) and it did not look that difficult

A pro helped me do a powerglide a long time ago and it was cake! I think I'd rather do autos than manuals. Craig

Helped a buddy work on his E4OD Ford in a 97 powerstroke. It was alot of work, and unless you are familiar, you need to go slow, check everything twice. We had to borrow special tools in order to disassemble/reassemble. I also went to to a trans shop and watched this guy slap the thing together while talking to me at BTS. He made it look easy.


I would say you could do it, but you must remember how everything goes back, and you need to be very organized. It also took use half of a garage laying everything out. It was a great learning project, but not something I would go through too often. Matter of fact, I am sure there was the "we should have paid someone to do this" muttered more than once.

Have fun,

Merry Christmas

depends on what you are calling a "rebuild". complete rebuild would mean you pull the od unit apart and reseal/reclutch it. this od job is NOT advised for a backyard type of deal. there is an approx 800 ft lb spring in the od unit that, if not taken apart correctly does have the ability to kill you. now if your just gonna replace clutches/seals/bands in the main unit, its not that bad. ive done 2-3 rebuilds in a day(when i felt like it), but then again ive been doing these for a couple years now. got any questions about it, ill try to help.

I've rebuilt a few. A518, 727, C-6, ford AOD, and turbo 350. They are not that bad to do. I would get a manual or and aftermarket tranny book that will give you some tips and tricks to make them stouter. Adding clutches drilling output shafts for better oil flow, etc. The toughest part of the auto is the valvebody and that is already figured out for you. I would get a new one, or at least a good shift kit. They each have their own tricks to figure out but once you get it they are pretty easy. Make sure everything is CLEAN!!! and you shouldn't have any trouble. Make sure to use lint free rags and MAKE SURE EVERYTHING IS CLEAN.
