Detailed Description

Standard Ignition SC806 is an automatic transmission input shaft speed sensor used to monitor transmission input shaft speed for the control system. Accurate speed input helps the transmission module manage shifting logic and related drivability functions.

Compatible With 2021-2024 Chevrolet Trailblazer, 2020-2022 Buick Encore, and 2019-2021 Chevrolet Malibu. The SC806 cross-references Monroe Shocks & Struts 172286 for the same application.

Common Problems This Sensor Can Address

• Transmission speed signal faults stored in the control module
• Harsh, delayed, or inconsistent shifting behavior
• Intermittent transmission warning lights related to input speed data
• Loss of accurate shaft speed feedback to the transmission controller
• Drivability concerns tied to a failing transmission input sensor

Installation Notes and Tips

Verify connector shape, terminal style, and mounting location before installation. The SC806 uses a bolt-on, trans-mount design with one bolt hole and a plug-in female connector, so matching the OE connector and sensor position is important for proper fitment. Confirm vehicle application by year, make, and model before service.
