Allison 29567151 Speed Sensor Assembly – Genuine Transmission Speed Sensor

The Allison 29567151 Sensor Assembly is a genuine transmission speed sensor designed for Allison automatic transmissions used in medium- and heavy-duty commercial trucks, buses, construction equipment, fire apparatus, refuse vehicles, and vocational applications. This precision electronic sensor monitors rotational shaft speed and provides critical input to the Transmission Control Module (TCM), allowing the transmission to calculate shift timing, torque converter operation, clutch engagement, and overall transmission performance.

Manufactured to Allison’s original equipment specifications, the 29567151 speed sensor delivers accurate rotational speed feedback in harsh operating environments. By continuously transmitting shaft speed data to the TCM, it helps ensure smooth gear changes, proper torque converter lockup, optimized fuel efficiency, and diagnostic accuracy. When a faulty speed sensor causes erratic shifting, limp mode, or diagnostic trouble codes, replacing it with a genuine Allison sensor helps restore dependable transmission operation.
