Product Details

Cardone’s Transfer Case Motor line focuses on direct-replacement service parts for electronically shifted transfer cases. Part number 48-101 is remanufactured using reverse-engineering feedback from failed units so original design weaknesses can be corrected during the rebuild process. The result is a transfer case motor intended to restore reliable engagement and shifting performance in applications including Chevrolet Trailblazer, GMC Envoy, and related platforms.

This part cross-references Chevrolet OE numbers 88935650 and 88996637 for the same application.

What It Helps Fix

• Service 4WD light illuminated
• Four-wheel drive inoperative in high or low range
• Transfer case motor failure to shift the case
• Weak or inconsistent motor engagement
• Error codes related to transfer case motor operation

Installation Notes and Tips

Before installing Cardone 48-101, manually shift the transfer case into the 2-wheel drive position. The replacement motor drive is factory-set in 2WD, and the transfer case must match that position during installation. Do not operate the motor while it is off the transfer case, as this can damage the unit and set an error code that must be cleared before operation resumes.

A crescent wrench can be used for the manual shifting operation. Confirm the vehicle uses a 7-terminal plug and rectangular harness plug before ordering.
