Restore Smooth Shifting to Your Buick Rendezvous
If your 2006-2007 Buick Rendezvous is suffering from harsh shifting, getting stuck in gear, or has an illuminated Check Engine Light, a faulty Transmission Control Module (TCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen these symptoms countless times. A failing TCM can turn a reliable vehicle into a source of constant frustration. This T42 Transmission Control Module, part number 24252114, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
This isn’t just a replacement part; it’s a restoration of your vehicle’s drivability and your peace of mind. The TCM is the brain of your automatic transmission, controlling every gear change, managing torque converter lockup, and monitoring for faults. When it fails, the symptoms can range from annoying to dangerous. Our module ensures your transmission receives the correct signals, restoring the smooth, predictable performance you expect from your Buick. By ordering this pre-programmed 2006-2007 Rendezvous TCM, you bypass expensive dealership programming fees and lengthy wait times.
From the Diagnostic Bay: The Intermittent Rendezvous Nightmare
I remember a 2006 Rendezvous that came into the shop with a classic ‘ghost’ problem. The owner complained of it randomly dropping into limp mode (stuck in 2nd gear) on his commute, but only once or twice a week. We couldn’t replicate it in the bay, and the only stored code was a generic P0700 (Transmission Control System Malfunction). After checking the wiring harness and solenoids, which all tested fine, experience pointed directly to the TCM. Heat cycles and vibration can cause internal solder joints to fail intermittently. We installed a VIN-programmed T42 module, and the customer called back a month later to say the problem was completely gone. This part saves hours of diagnostic guesswork and prevents a comeback.
Is Your Rendezvous Showing These Telltale Signs?
- ✔ Harsh, banging, or erratic gear shifts.
- ✔ The vehicle is stuck in ‘limp mode’ and won’t shift out of a single gear.
- ✔ Check Engine Light or Transmission Warning Light is on with codes like P0700, P0750, or other solenoid-related DTCs.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Complete loss of shifting capability or failure to go into gear.
- ✔ Noticeably worse fuel economy due to inefficient shifting.
DIY-Friendly Installation: A 30-Minute Fix
You don’t need to be a master mechanic to replace the 2006-2007 Rendezvous TCM. The process is straightforward and can be done with basic hand tools in your driveway.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and help reset the system.
- Locate the Module: On the 2006-2007 Buick Rendezvous, the TCM is conveniently located inside the air cleaner box. You will need to remove the air filter cover to access it.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old TCM. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical connectors. Ensure they click into place.
- Final Steps: Reassemble the air cleaner box and reconnect the battery terminal. While the module is plug-and-play, it’s good practice to use a basic OBD2 scan tool to clear any lingering fault codes from the vehicle’s memory.

Frequently Asked Questions
Does this module require programming at the dealership?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, with no extra programming or calibration needed.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module or dispose of it without the hassle of returning it.
What tools do I need for installation on my Rendezvous?
You will typically only need a basic socket set to remove the air cleaner box cover and unbolt the module. A flathead screwdriver may also be helpful for the air intake clamp.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause (like an internal TCM failure), you should use a scan tool to check for more specific codes (e.g., P0751, P0756) to confirm the diagnosis.
What does the one-year warranty cover?
