Restore Smooth Shifting to Your Buick Rendezvous
If your 2006-2007 Buick Rendezvous is suffering from erratic shifting, getting stuck in gear, or has an illuminated Check Engine Light, a failing Transmission Control Module (TCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen how a faulty TCM can make a reliable vehicle feel unpredictable and unsafe. This T42 TCM, part number 24255280, is the definitive solution, arriving expertly programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Case Study: A Tricky Diagnosis
A customer brought in a 2007 Rendezvous that would intermittently refuse to shift out of 2nd gear, but only after driving for 20+ minutes on a hot day. No other shop could pinpoint the issue because it wouldn’t act up when it was cool. After connecting my scan tool, I saw communication dropouts from the TCM as the engine bay heated up. This is a classic sign of internal circuit board failure in these T42 modules. We replaced it with a VIN-programmed unit, and the problem was solved permanently. This isn’t just a part; it’s a reliable fix for a very common and frustrating issue.
Is Your Buick Exhibiting These Transmission Issues?
A failing TCM acts as a faulty brain for your transmission, leading to a host of noticeable problems. Look out for these common indicators before a minor annoyance becomes a major failure:
- âś” Harsh, slamming, or delayed gear shifts.
- âś” Vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Diagnostic Trouble Codes (DTCs) are present, such as the generic P0700 or specific solenoid codes (e.g., P0751, P0756).
- âś” Sudden loss of power or failure to accelerate properly.
- âś” Poor fuel economy due to incorrect gear selection.
- âś” Complete failure to engage any gear (no forward or reverse).
A Straightforward Guide to Installation
For the 2006-2007 Buick Rendezvous, this is a repair most DIYers can handle in their own driveway in under 30 minutes. The TCM is conveniently located right under the air cleaner box, making it easily accessible.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: Open the hood and find the air cleaner assembly. The TCM is mounted directly underneath it.
- Access the TCM: Remove the air cleaner box. This usually involves loosening a few clamps and bolts.
- 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 your new, VIN-programmed TCM into place and securely reconnect the electrical harnesses.
- Reassemble and Finalize: Reinstall the air cleaner box, reconnect the battery terminal, and start the vehicle. It’s ready to drive! We recommend using a basic scan tool to clear any stored fault codes after installation.
