Useful Information

Description and Purpose:

Genuine Allison 6-Speed Transmission Control Module, with remanufactured condition and marked under Part number: 24266710, is specifically tuned for the 2009–2015 GMC Sierra and Chevrolet Silverado equipped with 8-cylinder engines. Designed for T14 and A50 automatic transmissions, it ensures seamless communication between the transmission and powertrain, keeping gear shifts accurate even under demanding conditions.

Why Replacement is Important:

When a TCM begins to fail, shifting becomes unpredictable, affecting both comfort and drivetrain longevity. Replacement ensures continued precision and reliability.

Impact on Vehicle Performance:

Restores shift consistency and preserves smooth throttle response, improving both towing stability and fuel efficiency.
