Frequently Asked Questions
What does a VIN-programmed TCM actually do?
VIN programming loads your truck’s specific software and operational parameters onto the module. This ensures it communicates perfectly with the Engine Control Module (ECM) and other vehicle systems, controlling shift points, torque converter lockup, and line pressure exactly as the manufacturer intended. It makes the installation truly plug-and-play.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, this is a very straightforward installation. The TCM is typically located in the engine compartment (on the RH rear side for the Canyon). The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It generally takes less than 30 minutes.
Will this fix my P0700 transmission code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s essential to have the other codes read (e.g., P0751, P0756) to confirm the issue is with the module or solenoids it controls. In a vast majority of cases where the TCM is faulty, this part is the correct fix.
Do I need to send my old module back?
No. We do not require a core return. You can keep or dispose of your old part at your convenience, saving you the hassle and cost of return shipping.
How do I ensure this is the correct part for my truck?
