can someone explain to me what it does
in a nut shell...it allows an automatic transmission to slip while the car is stationary....like a clutch that is pushed in. Then, when you step on the gas, it engages...and spins the driveshaft. different stalls mean different rpm speeds ...ie...a 2000 stall will slip till it gets to the 2000rpm level and then it will fully engage. Higher stalls are for higher torque, higher rpm engines...not for street. Most stock transmissions use a 1200-1500 stall...since most motors idle at 7-900rpms. Lock up torque converters actually lock in step with the engine, meaning 1-1 drive speed...the motors turning 2300rpms, and the trans is also. gives more mpg and less heat in the transmission. google it....if this is unclear
