Frequently Asked Questions
What exactly does a VIN-programmed TCM do?
A VIN-programmed TCM is loaded with the specific software and calibration files for your exact vehicle. This ensures it communicates perfectly with your Allure’s engine and other systems, controlling shift timing, line pressure, and torque converter lockup for optimal performance, right out of the box.
Is this module difficult to install?
Installation is straightforward for a competent DIYer or any professional mechanic. On the 2006-2009 Allure, the TCM is typically located in the lower air cleaner housing. The process involves disconnecting the battery, unplugging the old module, installing the new one, and reconnecting everything. It usually takes under an hour.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s essential to have the specific transmission codes read to confirm. This part is designed to fix the internal electronic failures that trigger these codes.
