Frequently Asked Questions
Will this module need to be programmed?
No. We pre-program the module to your vehicle’s VIN before shipping. It will arrive ready for a plug-and-play installation, with no additional programming or dealership visits required.
Where is the TCM located on my Buick Allure?
On the 2006-2009 Buick Allure, the Transmission Control Module is typically located inside or on the lower air cleaner housing in the engine bay, making it relatively accessible for replacement.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward and usually takes less than an hour. Simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Reconnect everything, and you’re ready to go.
How do I know for sure that my TCM is the problem?
While the symptoms listed above are strong indicators, the best way to confirm is with a proper diagnostic scan. Codes like P0700 (Transmission Control System Malfunction) are a general alert, often accompanied by more specific codes pointing directly to the TCM or the circuits it controls. If you see these codes along with erratic shifting, the TCM is the most likely culprit.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe and costly damage. Poor shifting can cause premature wear on internal transmission components like clutches and bands, eventually leading to complete transmission failure.
Does this part have a warranty?
Yes. This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
