TH350 Rebuild Tools
Hey all,
Now that I've almost finished rebuilding the motor (just a lot of cleaning up/painting accessory parts), I started to look at the leaks on my TH350. I found a rebuild kit at eatmyshift.com that looks like it includes pretty much everything that I need except for the tools.
I found a spring compressor for a fairly resonable price here:

But I am unsure on the bushing/seal driver kits. I found this one at summit:
http://www.summitracing.com/parts/OTC-4505/?rtype=10
Will that one work for the TH350 bushings?
Costplustools.com has one too, but theirs doesn't look like it can be used to drive in the seals:

Any suggestions?
Anyone know what size the bushings in the TH350 are so that I can find the right kit?
Thanks,
-Chris

That spring compressor will work good on the reverse piston- the one clear in the back of the case= it won't work real well on the other ones.
This is a K-D tool I've had for years. Works great on all GM transmissions- I've used it on the FWD 125's up to Allison 540's.
As far as bushings, About the only ones I've had to change were the front pump, output housing, and rear case bushing. I use the new one to drive out the old one. Just hit it flat and square. Even a miss isn't the end of the world. A pump bushing is $1.00.

When I rebuilt my th350 I had my case hot tanked by a local trans shop and had them replace all of the bushings while they were at it. I think total cost was about $70. It saved me from having to buy a bushing remover/driver tool which seemed like an expensive tool that I would only use once or twice. The drivers you show look pretty inexpensive but I can't tell if they will work for all of the bushings.
The book I followed said that TH350's are hard on bushings and recommended they all be changed. It said the bushings keep everything properly aligned so that oil makes it all the way to the rear of the trans. So for the price I figured it made sense to have them all replaced.
I made my own compression tool out of bar stock from Home Depot and a piece of all-thread. Total cost about $10.
While I was in there I had the direct piston, (I think), turned down on a lathe by a local machine shop to allow me to install 5 clutch discs. Depending on which version of th350 you have, you may find 3 clutches, 4 or 5. The other clutch packs will not require additional clutches and are strong enough as is, so I am told.

I bought that K-D Tool when I was building trannys all day- every day. Flat rate pay in a dealer is not real forgiving. Fast is money.
There are lots of ways to get around spending $200 bucks on tools that you won't use but a couple of times at most. Use the cash wisely.
