What are the symptoms of a faulty TCM?

A faulty Transmission Control Module (TCM) can present several noticeable symptoms, including:

  1. Erratic Shifting: The transmission may shift unpredictably, causing the vehicle to jerk or hesitate.
  2. Stuck in Gear: The vehicle might get stuck in a particular gear, often "limp mode," which restricts the car to second or third gear to protect the transmission.
  3. Transmission Slipping: You may notice the transmission slipping between gears, resulting in a lack of power and acceleration.
  4. Poor Fuel Economy: A malfunctioning TCM can lead to inefficient transmission operation, reducing fuel efficiency.
  5. Check Engine Light: The check engine light or transmission warning light may illuminate on the dashboard, indicating an issue with the TCM.
  6. No Gear Engagement: The transmission may fail to engage gears properly, leaving the vehicle unable to move.

If you experience any of these symptoms, it’s crucial to have your TCM inspected and repaired. Sending your TCM to UpFix can save you up to 80% compared to purchasing a new module.
