Gearbox Speed Sensor, Input Speed
The speed can be generated with the engine idling and the gear selector in P/N position. If the gear selector is in any other position, a gear is engaged and the gearbox input shaft is connected to the output shaft and an RPM will not be indicated until the car is driven. Depending on slippage in the torque converter the gearbox speed and the engine speed will differ when the lock-up function is not engaged. With lock-up engaged the gearbox speed should be the same as engine speed (RPM).
Measuring range (rpm): 0 - max. rpm
