If your 2006-2007 Buick Rendezvous is suffering from unpredictable shifting, getting stuck in gear, or has a persistent check engine light, you’re likely dealing with a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen how a faulty TCM can make a reliable vehicle feel unsafe and frustrating to drive. This isn’t just an inconvenience; it’s a critical failure that impacts your vehicle’s performance and fuel economy. This professionally programmed T42 TCM, part number 24235340, is the direct, reliable solution to restore your vehicle’s transmission to its proper operational state.
Case Study: A Tricky Diagnosis
A customer brought in their ’07 Rendezvous with a classic complaint: “It slams into gear sometimes, and other times it feels like it’s slipping.” The check engine light was on, and a scan revealed a generic P0700 (Transmission Control System Malfunction) code. While this code points to a transmission issue, it doesn’t pinpoint the cause. After checking the fluid and wiring, my experience pointed straight to the TCM. These T42 modules are known to fail internally over time, causing the exact erratic behavior described. We installed a VIN-programmed module, and in less than an hour, the car was shifting perfectly. The customer saved hundreds by avoiding a dealership visit for programming.
Is Your Buick Rendezvous Showing These Signs?
A failing TCM doesn’t heal itself; the symptoms only get worse. If you’re noticing any of the following, it’s time for a replacement:
- âś” Harsh, banging shifts or delayed gear engagement.
- âś” The vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
- âś” Check Engine Light is on with transmission-related Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid codes.
- âś” Inability to upshift or downshift, leading to poor acceleration and high RPMs.
- âś” A noticeable drop in fuel efficiency.
- âś” Intermittent loss of communication with the TCM, causing unpredictable behavior.
