Restore Your Pontiac G5’s Shifting Performance
Is your 2007-2010 Pontiac G5 suffering from harsh shifts, delayed gear engagement, or a frustrating 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 every shift with precision. When it malfunctions, it can lead to poor performance, decreased fuel economy, and even leave you stranded in limp mode. This genuine quality GM T42 TCM, service part number 24230461, is the definitive solution to restore your vehicle’s drivability and peace of mind.
We had a 2008 Pontiac G5 come in with the check engine light on and complaints of banging into gear. The owner had already replaced two shift solenoids based on a generic code reader’s output, but the problem persisted. After connecting our professional scan tool, we saw the classic P0700 (Transmission Control System Malfunction) code, but also intermittent communication loss with the TCM itself. This pointed directly to the module. Instead of throwing more parts at it, we installed a VIN-programmed T42 TCM. The communication was instantly stable, all codes cleared, and the car shifted like it just left the factory. It’s a reminder that sometimes the controller, not the component, is the root cause.
The Importance of a Programmed 2007-2010 G5 Transmission Module
Modern vehicles are complex, and the TCM must communicate flawlessly with the Engine Control Module (ECM) and other vehicle systems. A generic, unprogrammed module simply won’t work. Our key advantage is that we pre-program this module to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This critical step ensures that the module has the correct software and calibrations for your G5’s specific configuration. The result is a true plug-and-play installation that eliminates the need for an expensive trip to the dealership for programming. You can install it in your driveway and get back on the road immediately.
Common Symptoms of a Failing TCM
- ✔ Harsh, erratic, or delayed gear shifting.
- ✔ The vehicle gets stuck in one gear (limp mode), often 2nd or 3rd.
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are present.
- ✔ Failure to upshift or downshift properly.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ Inability to communicate with the TCM using a scan tool.
Installation and Compatibility
Installing your new 2007-2010 G5 Transmission Module is a straightforward process for any competent DIY mechanic. For the Pontiac G5, the TCM is typically located on the driver’s side strut tower in the engine compartment, making it easily accessible. 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. Because it’s pre-programmed, the vehicle will recognize it instantly. This module is a direct replacement for a wide range of GM service numbers, including 24252114, 24234503, 24230461, and many others, ensuring broad compatibility across the GM family of vehicles from 2006-2014 that utilize the T42 controller.
