Installation Notes and Tips

Verify connector style, bolt-hole mounting, and sensor location before installation. This sensor uses a female connector, pin terminals, and a bolt mount, so matching the original configuration is important for proper fit. Confirm whether your vehicle uses an input or output shaft speed sensor application, especially on Silverado, Sierra, Express, Savana, Tahoe, and Yukon models.

Inspect the connector, wiring, and transmission case opening for damage or contamination before installing the new sensor. Because the wiring harness is not included, reuse the existing harness connection if it is in good condition.
