Data from the input shaft speed sensor and output shaft speed sensor are compared by the transmission control module (TCM) or powertrain control module (PCM) to determine all of the following, EXCEPT:
A) Gear ratio
B) Clutch or band slippage
C) Amount of time it takes to shift
D) Engine misfires

Question

Quizplus · Accepted Answer

The TCM or PCM uses input and output shaft speed data to determine gear ratio, clutch or band slippage, and shift timing, but not engine misfires, which are detected by other sensors like the crankshaft position sensor.
