Restore Smooth, Reliable Shifting to Your Saturn Vue
If your 2007-2010 Saturn Vue is suffering from harsh shifting, getting stuck in gear, or throwing transmission-related error codes, a failing Transmission Control Module (TCM) is the most common culprit. Over my 20+ years in automotive diagnostics, I’ve seen countless GM vehicles sidelined by these exact issues. The TCM is the brain of your automatic transmission, and when it fails, it can make your vehicle feel unpredictable and unsafe. This isn’t just an annoyance; it’s a critical failure that impacts drivability and fuel economy.
This OEM-quality T42 TCM, part number 24234503, is the definitive solution. We take the guesswork and high cost out of the repair by pre-programming the module to your vehicle’s specific VIN. This means it arrives ready for a true plug-and-play installation, eliminating the need for an expensive trip to the dealership for programming. It’s designed to precisely manage shift points, torque converter lockup, and line pressure, bringing your transmission’s performance back to factory specifications.
Case Study: A Tricky Diagnosis
A customer brought in a 2008 Saturn Vue with an intermittent but severe bang when shifting from 2nd to 3rd gear. They had already replaced a shift solenoid with no improvement. A quick scan showed a P0700 general fault and a history of solenoid circuit codes. Instead of chasing electrical gremlins, we tested the TCM. We found that the module’s internal drivers were failing under load, causing the erratic commands. Swapping in a VIN-programmed TCM like this one resolved the issue in under an hour. The customer saved hundreds by avoiding further incorrect part replacements and dealership programming fees.

- âś” Harsh, erratic, or delayed gear shifts.
- âś” The vehicle is stuck in “limp mode” (usually 2nd or 3rd gear).
