Restore Smooth Shifting to Your Chevrolet Malibu
If your 2006-2010 Chevrolet Malibu is suffering from harsh shifts, getting stuck in gear, or throwing transmission codes, the culprit is often a failing Transmission Control Module (TCM).

This T42 Transmission Control Module, part number 24235340, is the definitive solution to get your car driving like new again.
What sets this module apart is our commitment to a seamless repair. We pre-program each unit to your vehicle’s specific VIN before it ships. This means no expensive trips to the dealership for programming, no special scan tools required for setup—just a straightforward, plug-and-play installation. This isn’t just a part; it’s a complete, hassle-free fix designed for both professional mechanics and DIY enthusiasts.
From the Diagnostic Bay: A Malibu’s Mysterious Limp Mode
A customer brought in a 2008 Malibu that would intermittently go into ‘limp mode’—stuck in 3rd gear with the check engine light on. They’d already replaced a shift solenoid based on a generic code, but the problem persisted. After pulling the codes, I saw a P0700 (Transmission Control System Malfunction). Instead of just throwing more parts at it, I checked the TCM’s communication. The data stream was erratic. We installed one of our VIN-programmed T42 modules. The swap took less than 20 minutes. After a quick battery disconnect to clear the memory, the car shifted perfectly. It’s a classic case where the brain (TCM), not the muscle (solenoids), was the issue. This is why a quality, correctly programmed 2006-2010 Malibu TCM is so critical.
