Is Your Malibu’s Transmission Acting Up?
Are you dealing with the frustration of harsh, erratic shifting, a flashing check engine light, or your car suddenly going into “limp mode”? Before you brace for a costly transmission rebuild, the problem is often a failing T42 Transmission Control Module (TCM). This critical component is the brain of your automatic transmission, and when it fails, it can cause a host of alarming issues. We offer the definitive, plug-and-play solution with our expertly programmed GM T42 TCM, designed to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty TCM is the likely culprit. This module is the direct fix for these problems, restoring the smooth, reliable operation you expect from your vehicle. Don’t let a small electronic part sideline your car; this is the component you need to get back on the road safely.
- Harsh or Delayed Shifting: Abrupt gear changes, slamming into gear, or a noticeable lag when shifting.
- Stuck in Gear / Limp Mode: The vehicle refuses to shift past 2nd or 3rd gear as a protective measure.
- Check Engine & Transmission Lights: Often accompanied by Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related codes.
- Poor Performance & Fuel Economy: Inefficient shifting leads to decreased MPG and sluggish acceleration.
- Complete Communication Failure: In severe cases, the TCM stops communicating with the vehicle’s other computers, leading to a no-shift condition.
This pre-programmed unit is the reliable fix for your 2006-2010 Malibu transmission control module issues and a wide range of other GM vehicles facing the same symptoms.

Frequently Asked Questions
Do I need to take my car to a dealer after installation?
No. This module is pre-programmed to your vehicle’s VIN. It is designed to be a plug-and-play installation, eliminating the need for any additional programming from a dealership or mechanic, which saves you significant time and money.
Is this TCM difficult to install?
For someone with basic mechanical skills, installation is straightforward. The TCM is typically located in the engine bay and is accessible. The process usually involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It often takes less than 30 minutes.
How do I know for sure that my TCM is the problem?
The most common indicators are specific transmission-related trouble codes (like P0700), the vehicle being stuck in limp mode, and erratic shifting that isn’t related to low fluid levels. If you are experiencing these electronic symptoms, the TCM is the most probable cause.
What does a Transmission Control Module do?
The TCM is the central computer for your automatic transmission. It receives data from various sensors (like vehicle speed and engine RPM) and uses that information to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smoothness.
Will this fit models other than the 2006-2010 Chevrolet Malibu?
Yes, absolutely. This T42 TCM is compatible with a very wide range of General Motors vehicles from 2006-2014, including many Chevrolet, GMC, Buick, Cadillac, Pontiac, and Saturn models. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe issues. Poor shifting can cause premature wear on internal transmission components like clutches and bands, potentially leading to a complete mechanical failure that is far more expensive to repair.
