    It is actually a "torque converter" and it acts as a fluid coupling between the engine output shaft and the transmission input shaft.

    3200 is the stall speed of the converter. Meaning at 3200 rpm and higher, the converter slip speed is nearly zero. What that means is the engine and transmission input shaft are spinning at nearly the same speed above 3200rpm

    Below 3200 is where the magic happens. It like slipping a clutch in a manual transmission from idle to 3200. The stock converter only slips from idle to about 1800 rpm.

    The stall also provides tq multiplication in flash. That is one reason why stalled auto's can 60' so hard.
