torque converter?
I have the stock torque converter in the original TH 350 that came with my car. I think it is broken, but was wondering if anyone has any ideas.
My car shifts fine. When I get on it, it shifts at anywhere around 5,000 rpm witht he gas pedal on the floor. However, if I get on it from a standstill, the rpms come up, but the tires won't break loose. Instead, it makes this noise that sounds like a combination of an arc welder and someone ripping a very heavy piece of paper. If I let off the gas a little bit, it stops making the noise and continues accellerating normally.
Please note that when it makes its pattented noise, the car is accellerating with great force. Just wont squeal the tires. However, in reverse, it will burn those tires like a madman.

Reverse is a shorter gear than 1st?
Can't say I've heard the noise you describe. Maybe the clutch packs in the auto? - although that is more a pronounced jerking with a higher pitch noise in my experience.
What ever it is, it doesn't sound good.

I have a complete rebuilt TH 350 in my garage if I have to do a swap. I could just swap and have the original tranny rebuilt and keep it in the sealed barrel in my garage until I do the frame off or break the extra tranny.
My problem is that I don't have a lift and don't want to pay labor for someone else to do it.

Simon, any guy that dips, listens to country and likes 4W-Driving, should be able to swap those trannies in an afternoon without a lift. I did my own TH400 install and it is a bigger heavier tranny than the TH350. I'm also a fat old man with arthritis. :D
All I used were jackstands, a floor jack and some wooden blocks. The hardest part was dealing with the tranny cooling lines. If you can get a buddy to help it would even be easier to do.
Just use some redneck ingenuity and get to it!

So changing the tranny in a nice warm garage isn't too tough, huh? I have tons of tools, a real good floor jack, and a few good jackstands. Hmmm... I may go looking for a new torque converter for the extra tranny. What stall should I get for an all stock L-82?

Re: torque converter? (Simon Alexander)
Just make sure you have at least 16 inches ground clearance to slide the tranny out. :yesnod:
As for stall speed probably 2000-2200. Search for my recent threads regarding my stall speed.

In reverse the wt. is lifted from the rear wheels. The Corvette IRS works well. What you want is acceleration!
:cool:
