Ok, I'm getting into automatic transmission rebuilds at work, and so far have only needed to do Chrysler, and Mitsubishi transmissions. I hear that some of them that I have done are the hardest ones out there. I didn't think it was all that bad.

Now, I'm planning to build my own transmission for my car, and we have one in needing a rebuild right now, so I just would like to know what tools are needed. Any other advice for assembly, and things to look for would be appreciated!

Will anyone ever buy all these? Most of them are overpriced junk.

I rebuilt mine completly: every piece removed, inspected, repaired/replaced, and reassembled without using any special tools, and doing it correctly. I admit I used c-clamps, servo housing, pitman arm puller, hose clamps and a bunch of plastic dixie cups as special tools... And a dial indicator, feeler guages of course.


You could buy and price these tools online at http://www.spxkentmoore.com/ but when you see the prices your going to sh:t a brick!

You could probably buy 5 remanufactured transmissions cheaper than the tools to rebuild one.

 

Thanks for the info! I suppose that some of the tools I have already made to work for the Mopar tranny's (clutch spring compressor, etc....) may be all that I need. Fortunately, I'm gonna have one to play around with, as the customer needs it ASAP (don't they always) and we can get them a used one pretty fast. I'll get to keep the core (broken 4WD case) to play with to figure out what I'm doing, and I can make the tools that I need, before I actually NEED them.

One thing I think I might get will be the pump alignment band, and the servo compressors may be handy, too. I have put pumps together without the band and pin with no problem before, but I think the tools would make it nice.

I also think some of the tools get in the way (at least some of them for Mopar's have) so I will figure it all out when I get one apart.

If anyone else has anything to add, please do!

Thanks!

Get an ATSG rebuild manual for your transmission and study it carefully before teardown. Most operations requiring special
tools, such as installing the teflon rings on the input shaft, can be done by a local
rebuild shop for a reasonable price. As Joel
said, most transmission tools are very expensive. Because of this, I have made most of mine.

 

Don't bother with that special tool....

Just rebuild your pump before you start putting stuff back into the case and stick it in the case upside down (less the o-ring) and align the holes with a bolt or something. Tighten the bolts up and pop it out... Perfectly aligned!

 

I have also been making my own tools. Big money saver, especially since I have access to the equipment I need to make them (Mill, lathe, welder, etc....) ANd, yes, they are expensive!

I really don't like the idea of taking stuff to a tranny shop, because the only local one sucks, and the shop I work for is sort of competition for them (we do everything, the do just tranny's)

I never thought to put the pump in backwards! Great idea!

Thanks for the help guys! I have the first one almost done! I just need to make another tool in the morning to get the Lo-Reverse piston return spring compressed. If anyone has the tool handy, could you please measure the Inside and outside diameters of the part that contacts the spring retainer? If I don't hear anything, I'm gonna go with 3.25 I.D. and 4.00 O.D..

Thanks for the tip on the ATSG manuals. Nice book! Very detailed! I'm gonna get one for every tranny that I do from now on! It just so happens that the shop I get rebuild kits and conmvertors from carries them. They also carry the Trans-Go recalibration kits! :-)

Thanks for all the help!

 

www.trannyman.com has the few tools you may need, and a bit less expensive than kent moore..

 

Thanks! I'll check that one out!

The main thing I need now, is the seal tool. The one that's like a feeler gauge, or the one that's like a loop of wire. I have made all the spring compressors that I think I need, and they have worked for the Chrysler tranny's that I've done, too (That's what I've made them for, as they seem to be really weak tranny's!)

Anyone know of any other good transmission web sites? I have been to a few.

Tahnks again!

From what I understand on these is there are two types... One is a wire loop on a stick and the other one is just a feeler guage mounted on a long handle...

I got away with just using a feeler guage.

 

Well, I didn't have much luck with the feeler gauge on the reverse clutch piston seal. It took me forever to get it in there! For the most part, the others went in ok. I can also use them on some of the other transmissions that I do (GM, Mopar, Ford, Imports, etc.....)
