Is Your Buick Lucerne’s Smooth Ride Ruined by a Jerky Transmission?
There’s nothing more frustrating than when a comfortable, premium car like your 2006-2011 Buick Lucerne starts shifting harshly, hesitating between gears, or even getting stuck in limp mode. That smooth, effortless acceleration you expect is gone, replaced by clunky, unpredictable performance. In my 20+ years as a diagnostician, I’ve seen this exact scenario countless times. The culprit is almost always a failing Transmission Control Module (TCM), the electronic brain that orchestrates every shift.
A Mechanic’s Real-World Experience
“A customer’s 2008 Lucerne came into my shop last month with a check engine light and what he described as ‘violent’ shifting from 1st to 2nd gear. The scanner showed a generic P0700 code. Another shop had already replaced a shift solenoid, but the problem persisted. We quickly identified the real issue: the TCM itself was sending erratic signals due to internal circuit failure, a common problem caused by years of heat and vibration in the engine bay. Replacing the module with a VIN-programmed unit like this one solved the problem instantly, restoring the car’s luxury feel.”
The Direct Solution: A VIN-Programmed Replacement
This T42 Transmission Control Module is the definitive solution for your vehicle’s transmission woes. We take the hassle and guesswork out of the repair by pre-programming the module to your car’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives ready for a true plug-and-play installation, with no need for an expensive trip to the dealership for programming. It’s designed to restore the precise, reliable shifting your Lucerne had when it was new.

Plug-and-Play Installation: Get Back on the Road in Under 30 Minutes
You don’t need to be a master technician to perform this repair. The TCM is located in an accessible spot in the engine bay, making for a straightforward swap.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the onboard systems.
- Locate the Module: On your 2006-2011 Buick Lucerne, the TCM is found in the left-hand (driver’s side) engine compartment. It’s a silver box with electrical connectors.
- Swap the Part: Carefully unplug the wiring harnesses and unbolt the old module. Mount the new module in its place and securely reconnect the harnesses. You should hear a click as they lock in.
- Final Steps: Reconnect the battery terminal. While the module is pre-programmed, it’s always good practice to use a basic OBD2 scan tool to clear any stored diagnostic trouble codes (DTCs) from the vehicle’s memory.
