Restore Your Allure’s Shifting Performance
Is your 2006-2009 Buick Allure suffering from erratic shifting, getting stuck in gear, or displaying a check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating smooth gear changes, managing torque converter lockup, and monitoring system health. When it fails, it can cripple your vehicle’s drivability and leave you stranded. This OEM-quality T42 TCM, part number 24235732, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
From the Diagnostic Bay
We recently had a 2008 Buick Allure come into the shop with a classic complaint: “It bangs into gear and sometimes won’t shift past second.” The customer was worried about a costly transmission rebuild. A quick scan revealed a P0700 code, which is a general transmission fault request. Digging deeper, we found several solenoid circuit codes. Instead of chasing individual solenoids, our experience pointed directly to the T42 TCM, a common point of failure. We installed one of these VIN-programmed modules, cleared the codes, and took it for a test drive. The shifts were crisp and smooth, just like it came from the factory. The customer was thrilled to have their car back on the road for a fraction of the cost of a new transmission.
Common Symptoms of a Failing TCM
If your vehicle is experiencing any of the following issues, a faulty TCM is the likely culprit. Replacing it can prevent further damage to your transmission’s mechanical components.
- ✔️ Harsh Shifting & Delayed Engagement: Noticeable clunks, bangs, or hesitation when the transmission shifts between gears.
- ✔️ Stuck in Limp Mode: The vehicle may refuse to shift out of a single gear (often 2nd or 3rd) to protect the transmission from further damage.
- ✔️ Warning Lights: The Check Engine Light or a dedicated transmission warning light will illuminate on your dashboard.
- ✔️ Diagnostic Trouble Codes (DTCs): You’ll often see codes like P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0750, P0753, P0758).
- ✔️ Poor Fuel Economy: Inefficient shifting and torque converter operation can lead to a significant drop in your vehicle’s MPG.
- ✔️ No Shifting: In severe cases, the transmission may fail to upshift or downshift at all, making the vehicle unsafe to drive.

Frequently Asked Questions
Do I need to program this module after I receive it?
No. This module comes pre-programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, eliminating the need for an expensive trip to the dealership for programming.
Where is the TCM located on my 2007 Buick Allure?
On the 2006-2009 Buick Allure, the Transmission Control Module (TCM) is typically found attached to the lower air cleaner housing in the engine compartment, making it relatively easy to access for replacement.
Will this fix a P0700 transmission code?
A P0700 code is a general fault indicator, meaning the TCM has detected a problem and requested the check engine light. While this module often resolves the root cause (such as internal solenoid circuit faults that trigger the P0700), you should always diagnose any other accompanying codes to confirm the TCM is the issue.
