Is your Buick Rendezvous shifting erratically, getting stuck in gear, or showing a check engine light? These are classic signs of a failing Transmission Control Module (TCM), a critical component that acts as the brain for your automatic transmission. A faulty TCM can make your family vehicle feel unreliable and unsafe. Restore dependable performance with our pre-programmed T42 TCM, the definitive solution for getting your SUV back on the road with confidence.
Common Symptoms & Your Solution
When the TCM begins to fail, your vehicle will let you know. You might experience sudden, harsh shifts between gears, a frustrating delay when shifting from park to drive, or the vehicle may enter a “limp mode,” locking itself into a single gear to prevent further damage. You’ll likely see a check engine light or a specific transmission warning light on your dash, accompanied by diagnostic trouble codes (DTCs) like P0700, P0750, or various solenoid-related codes. This isn’t just an annoyance—it affects fuel economy and can lead to more severe transmission damage if ignored.
