Pioneer Automotive CA-1980 Automatic Transmission Detent Cable

The Pioneer Automotive CA-1980 is a replacement automatic transmission detent cable, also commonly known as a kickdown cable or throttle valve (TV) cable. This cable links the throttle body or carburetor to the automatic transmission, signaling the transmission to downshift when the accelerator is fully depressed — a critical function for proper shift timing, transmission line pressure, and overall drivetrain performance. A worn or broken detent cable can cause erratic shifting, delayed engagement, or transmission damage, making timely replacement essential.

Fits a wide range of 1976–1999 Chevrolet, GMC, Pontiac, Buick, Oldsmobile, and Cadillac applications across 710 vehicle configurations.
