I'm new here and I was wondering what exactly a torque converter does. I know its a round thing in your auto tranny that connects the crank coming from the engine to the rest of the tranny. What does "lock up" mean? What is "stall speed"? What are the pros and cons of having a higher stall speed?
thanks

I wrote a brief intro on torque converters. Go to www.kennedysdynotune.com and look at the left hand menu. Click on "Tech Tips" and follow the link to "Torque Converter Tech".
