what is it????????

 

well.. its kinda like...

normal(Stock) its set around 900 or so,... not sure...

well this.. (depends on what u get), but say u get a 2400... you wont start moving till rpm is 2400+ hence.. u slam gas... VROOOM< once at 2400 LOCKS up... 8'] i dont have one.. i just know what they are.. not sure if bad on tranny or not... 8']

The torque converter takes the place of a clutch in cars with automatic transmissions. It is a "donut" shaped object that bolts to the flywheel of the engine, and is mated to the input shaft of the transmission on a set of splines. As the engine speeds up, the converter begins to make a positive connection between the motor and tranny, and eventually starts to move the car.

Factory converters "stall" between 1600-1800 RPM, and what this means is that upto ~1800 RPM, the engine can spin faster than the shaft into the transmission, but once the converter hits ~1800, the torque converter in essence "locks" (same as engaging a clutch) and 100% of the engine speed & power is sent through the tranny.

High stall converters (ie: 2400, 3200, 3600, etc.....) will allow the engine to rev to those higher RPM's (ie: 3200 RPM) before it "locks", so the advantage is that the engine is revving closer to its power-band. Even with a stall converter though, the car can still drive when the engine is turning slower than the stall speed, all that's occuring is that the converter is "slipping" a lot (like slipping a clutch) and that's where automatics + stall converters are not as good for normal daily driving since the extra slippage causes a lot of heat build-up inside the transmission, so to help that, most guys (should) install a separate transmission cooler when adding a stall converter.

Hopefully that explains it a little better for ya.

In my words, torque converter, your best friend........
