RE: torque converters???
the converter connects to the flywheel and to the trans. its allows the engine to run while the car is in drive and the car not move. at low rpms (idle) the converter slips and thats why the car can sit at a stop light. the higher the rpm the less the converter will slip. at about 1800 i think, the stock converter is no longer slipping at all. the higher the stall speed, the higher you can get the rpms up before the car really begins to move. it will move a bit with a high stall but not untill you get higher in the rpms. this is helpful in a drag race because you can get the rpms higher (where the power is) before the trans locks to the motor which means more power at the launch. 2400 is a good speed for a street car. if you do get a converter, buy a trans cooler!! the extra sliping the high stall converter does will heat the trans up quite a bit. a good cooler from b&m is $50.

RE: torque converters???
with a stall the tranny is actually slipping. this creates heat. a smaller converter has less slippage then a higher one but ahigher one matches your powerband better.
i got a 3k on my car and it peformed nicely, i also have another 3k stall for sale.. if interested its a B&M holeshot 3000, along with a transgo shift VB and a pro billet servo

If you go out and put your car in gear and hold the brake while giving it the gas, you will notice the rpm's stop at a certain point and won't rise anymore (unless you start spinning the rear wheels) this is the "stall speed." Don't do it for very long and put trans in N for 30 secs afterward to let the oil cool.

The AOD does not have a lock up converter, however the AODE and 4R70W do. Lock up is almost like having an extra gear. It was made to help with emissions and fuel mileage.
