T 350 help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a question about a t 350 transmission, I would like to know if it is ok to use the torque converter out of a tranny that went bad. The converter itself was rebuilt just over 1000 miles ago, but i was worried about leaving the burnt fluid in it. Is there a way to get most of it out, or will it not hurt anything, or should i try to find another one.

Thanks for any help

David

You could have it flushed, I alway's like to put new part's in while it's all apart..

Most transmission shops will void the warrenty on a rebuild if a new converter is not used...it could be full of metal and there is no way to get it out without taking it apart

well, to be honest, i was tring my luck with a junkyard one, and was going to have it rebuilt if it doesn't work, but if it works when i get it installed, i will most likely leave it in until it needs something.

Thanks

You can drill a hole in the converter and drain it. Then use a rivet to plug the hole. I have a book on rebuilding the TH350 and it explains how to do it. Honestly, it looks like a pain in the rear. New, stock converters aren't very expensive - around $80. According to the buck, there are so many things that can go wrong with the torque converter, that it would be worth the $80 for a new one.

If your seriously thinking about rebuiling the converter, you should check to see if your local library has any books on rebuilding a TH350/400. I'd be concerned about metal fragements getting into the torque converter from a dead transmission.

If you were closer, I'd gove you one of the 3 known good ones I have laying here in my basement.
I would probably pass on that idea. The converter just holds too much crap in there and if your junk yard unit is OK, then you are just throwing one more variable into the mix.
Call a couple parts stores, you may actually be suprised at what a stock verter costs. I think I remember getting one for 50 bucks brand new at a parts store 10 years ago or so.
