what is the pupose of torque converter?!?
I have strong knowledge of engine operation and troubleshooting but transmissions are chinese. All I know is the torque converter sits between the flywheel and the auto tranny and you put tranny fluid in it. I believe it has something to do with when the tranny shifts or acts as a clutch but I have no idea.
Could somebody please enlighten me, also I see people here swapping for aftermarket converters, what are the advantages and estimated performance improvements of a higher or lower stall(?) or whatever. Thanks a lot!!!

Thanks a lot! That site pretty much sumed up my Q's, I had to go to a link on there for the performance aspect of it, though. I appreciate it, and for everyone, here's a quick excerpt from the site that pretty much answered my question. Thanks!!

Why do I need a higher stall speed converter?
Theoretically, for maximum acceleration the stall speed of the torque converter should match the peak torque rpm of the engine. A good explanation for the way it works is this: when you go outside jogging you start to breathe in and out faster and harder. Well the same thing goes for a performance engine. The engine is breathing in and out harder and faster, at a higher rpm. If a high performance engine makes power at a higher rpm, then a higher stall speed torque converter is what you need to put more power to the ground quicker.

Why is a torque converter the best performance upgrade money can buy?
No other upgrade to your vehicle can affect your performance better than a torque converter, except maybe nitrous oxide or possibly a supercharger. Consider the price of a supercharger, or the potential damage of nitrous in comparison to the cost effectiveness of a torque converter upgrade. Tests have shown that the correct torque converter can reduce 1/4 mile times by .3 to .7 seconds. And you get this benefit every time you step on the gas in everyday driving.
