Restore Peak Performance to Your Cadillac’s Transmission
Is your 2006-2011 Cadillac DTS suffering from erratic shifting, delayed gear engagement, or a persistent check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it falters, it can lead to poor performance, decreased fuel economy, and potentially severe transmission damage. This OEM-quality T42 TCM, service number 24241806, is the definitive solution to restore the smooth, reliable operation you expect from your vehicle.
From the Diagnostic Bay
We had a 2008 Cadillac DTS come in with a P0700 code and complaints of harsh 1-2 shifts. The previous shop had already replaced two shift solenoids, but the problem persisted. After a quick data scan, we noticed the TCM was commanding shifts erratically, even at a standstill. Instead of throwing more parts at the transmission itself, we identified the root cause: a faulty TCM. After installing one of our pre-programmed modules, the car shifted perfectly. This saved the customer hundreds of dollars and the headache of unnecessary internal transmission work. Always check the controller before condemning the hardware.
Common Symptoms of a Failing TCM
- ✔ Harsh, erratic, or delayed gear shifts that disrupt your drive.
- ✔ The vehicle enters “limp mode,” often stuck in 2nd or 3rd gear.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ Complete failure to upshift or downshift, leading to poor acceleration and high RPMs.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ Intermittent loss of communication with the TCM, causing unpredictable behavior.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the primary benefit of our service. We pre-program the module to your vehicle’s specific VIN before shipping. It arrives ready for plug-and-play installation, with no additional programming required.
Where is the TCM located on my 2007 Cadillac DTS?
On the 2006-2011 Cadillac DTS, the Transmission Control Module is typically found in the engine bay, on the right-hand (passenger) side, near the front of the vehicle.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the ECM to turn on the check engine light. While a failing TCM is a very common cause for this code, it’s essential to scan for more specific transmission codes (like P07xx) to confirm the diagnosis. This module is designed to resolve internal TCM faults that trigger these codes.
