Is Your Cadillac DTS Shifting Erratically?
There’s nothing more frustrating than when your luxury sedan starts acting up. If your 2006-2011 Cadillac DTS is experiencing harsh, delayed shifts, getting stuck in gear, or has the check engine light on with transmission codes, the problem is very likely a faulty Transmission Control Module (TCM). Over my 20+ years in the shop, I’ve seen this exact issue countless times. The constant heat cycles in the engine bay eventually take their toll on the delicate electronics inside the original TCM, leading to unpredictable and unsafe driving conditions.
Expert Pro Tip: Check Your Connector First
Before installing your new module, take a bright light and carefully inspect the pins on the vehicle’s wiring harness connector. On the DTS, this TCM is located in the right-hand (passenger side) front of the engine compartment where it can be exposed to moisture. Look for any signs of green or white corrosion. If you see any, clean it thoroughly with a small brush and electrical contact cleaner. A poor connection can cause the exact same symptoms as a bad module, and this five-minute check can save you a world of diagnostic headaches.
The Direct Solution: A VIN-Programmed T42 TCM
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take this high-quality T42 TCM, which is a direct replacement for part number 24235732, and program it specifically to your Cadillac’s Vehicle Identification Number (VIN). This critical step ensures the module has the latest GM software and communicates flawlessly with your car’s other computers right out of the box. You get restored performance without a mandatory, expensive trip to the dealership for programming.
Symptoms a New TCM Will Correct:
- โ Harsh, banging, or erratic gear shifts.
- โ Vehicle stuck in “limp mode” (usually 2nd or 3rd gear).
- โ Check Engine Light or Transmission Warning Light is on.
- โ Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- โ Failure to upshift or downshift correctly.
- โ A complete loss of communication with the TCM.
