Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing TCM is the likely culprit. This module is engineered to resolve these problems directly:
- Harsh or Delayed Shifting: Abrupt gear changes, slipping between gears, or a noticeable delay when shifting from park to drive.

- Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dash.
- Diagnostic Trouble Codes (DTCs): Your mechanic finds codes like P0700 (Transmission Control System Malfunction), P0750, or other solenoid-related faults.

An Expert’s Note on VIN Programming

Our pre-programming service is the critical step that makes this a true plug-and-play solution. It saves you from the headache of towing your vehicle to a dealer and paying hundreds in programming fees, turning a complex repair into a manageable one.
