Restore Flawless Shifting to Your GM Vehicle
Is your 2006 Pontiac Pursuit, or another GM vehicle, suffering from erratic shifting, getting stuck in gear, or displaying transmission-related warning lights? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change, managing torque converter lockup, and monitoring system health. When it fails, your driving experience can become unpredictable and frustrating. This OEM-quality T42 TCM, part number 24235754, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
Diagnosing a Defective Transmission Control Module
A faulty TCM can manifest in numerous ways, often mimicking mechanical transmission problems. Before condemning expensive hard parts, it’s crucial to evaluate the module. Common indicators include a flashing transmission light, the check engine light illuminating with codes like P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0751, P0756). You might experience harsh, delayed, or missed shifts, a sensation of the transmission slipping between gears, or the vehicle entering ‘limp mode,’ where it remains in a single gear (usually 2nd or 3rd) to prevent further damage. These issues not only affect performance but can also lead to decreased fuel economy and potentially cause long-term damage to your transmission if left unaddressed.
From the Diagnostic Bay
We had a 2008 Silverado in the shop with what the owner described as ‘violent’ shifting from 1st to 2nd gear. He had already spent a fair amount of money replacing the shift solenoids, but the problem persisted. After hooking up our diagnostic scanner, we noticed the command signals from the TCM were erratic. The module itself was failing internally, sending incorrect voltage to the new solenoids. We installed a VIN-programmed T42 module, cleared the adaptive learning tables, and the truck shifted like it just rolled off the factory floor. It’s a powerful reminder that the controller is just as critical as the mechanical parts it commands.
The Superior Solution: A Programmed 2006 Pursuit TCM
What sets this module apart is our expert VIN programming service. When you order, we flash the module with the latest GM-certified software specific to your vehicle’s Vehicle Identification Number. This critical step ensures that the TCM communicates flawlessly with your vehicle’s engine computer (ECU) and other onboard systems. It eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. Your vehicle will recognize the new module instantly, restoring original performance, shift points, and fuel efficiency strategies. This is the most reliable way to fix the root cause of many common transmission diagnostic trouble codes.

Simple Installation Process
Replacing the TCM is a straightforward job for a DIY mechanic or any professional technician. The module is typically located in the engine bay for easy access. Common locations include the LH strut tower (as in the Pontiac Pursuit and G6), next to the battery (in many trucks like the Silverado and Tahoe), or under the air cleaner box (in models like the Impala and LaCrosse).
- Safety First: Always disconnect the negative battery terminal before beginning work. This prevents electrical shorts and helps reset the vehicle’s electronic systems.
- Locate and Remove: Identify the old TCM based on your vehicle model. Carefully disconnect the electrical connectors and unbolt the module from its bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the wiring harnesses.
- Final Steps: Reconnect the battery. While the module is plug-and-play, it is best practice to use a capable OBD2 scan tool to clear any stored transmission fault codes to ensure a clean slate for the new part.
With no core charge, you can complete the repair without the hassle of returning your old part. Get your vehicle back on the road quickly and confidently with a part designed for dependable, long-term operation.
Frequently Asked Questions
What does ‘VIN Programmed’ mean for this TCM?
It means we load the module with your vehicle’s specific factory software using your VIN before we ship it. This ensures it works perfectly with your engine and other systems right out of the box, avoiding the need for expensive dealership programming.
Will this fix a P0700 trouble code?
A P0700 code indicates a general fault in the transmission control system. While this module is a very common cause and solution for this code, a full vehicle diagnosis is always recommended. This part is designed to resolve issues originating from a faulty TCM itself.
Is this part difficult to install myself?
For most individuals with basic mechanical skills, the installation is straightforward. The module is usually in an accessible location in the engine bay. The process involves disconnecting the battery, unplugging connectors, swapping the module, and reconnecting everything. Most installations take less than 30 minutes.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, which simplifies the purchasing and installation process for you.
