Transmission Speed Sensor Replacement
Erratic automatic shifting, speedometer needle dropping, Check Engine light on, or vehicle stuck in limp mode? Replacing a transmission speed sensor restores accurate rotational readings for smooth gear changes.The Transmission Control Module (TCM) continuously compares input shaft speed against output shaft speed to calculate gear ratios, execute precise shift timing, determine torque converter clutch lockup, and monitor for internal clutch slippage.
