Is Your Cadillac SRX Shifting Erratically?
If you’re experiencing harsh shifting, delayed gear engagement, or seeing transmission-related warning lights on the dash of your 2007-2009 Cadillac SRX, a failing Transmission Control Module (TCM) is a very likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating precise, smooth shifts based on data from various sensors. When it begins to fail, it can cause a host of drivability issues that can be frustrating and even unsafe.
Don’t let a faulty module keep your luxury SUV sidelined. This is a direct-fit replacement Transmission Control Module, part number 24235224, also compatible with 24239785 and YLMU. The critical difference with our service is that we program the module specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This means it arrives ready for installation, loaded with the latest GM software updates to ensure optimal performance and longevity, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2008 Cadillac SRX come into the shop with the classic symptoms: the transmission was stuck in ‘limp mode’ (3rd gear only), and the check engine light was on with codes P0752 (Shift Solenoid ‘A’ Stuck On) and U0101 (Lost Communication with TCM). The customer had already replaced the solenoid pack, but the problem persisted. After confirming power and ground at the TCM connector were good, we knew the module itself was the issue. A common mistake is to just swap in a used module, but that never works due to the VIN-specific security programming. We installed one of our pre-programmed modules, performed a quick throttle body relearn, and the vehicle was shifting perfectly again. Programming it beforehand saved the customer hundreds in dealership fees and got them back on the road the same day.
Common Symptoms of a Failing SRX Transmission Control Module
- ✔ Check Engine Light or other warning lamps illuminated
- ✔ Transmission stuck in one gear (limp mode)
- ✔ Harsh, jerky, or delayed shifting between gears
- ✔ Inability to shift into certain gears
- ✔ False neutral, where the engine revs but the vehicle doesn’t move
- ✔ Diagnostic trouble codes (DTCs) related to solenoids, sensors, or communication errors (e.g., P0700, U0101)
- ✔ Poor fuel economy due to inefficient shifting
The Plug-and-Play Solution for Your Cadillac
The complexity of modern vehicle electronics can make transmission repairs daunting. This pre-programmed SRX Transmission Control Module removes the biggest hurdle: the software. By providing us with your VIN during checkout, you receive a unit that is a true plug-and-play solution. Our technicians use GM-certified equipment to flash the module with the most current software available, which often corrects factory flaws and improves transmission behavior.
This module is located in the right-hand front of the engine compartment on the SRX, making it accessible for a competent DIY mechanic or any professional repair shop. Replacing the module is a matter of disconnecting the battery, unplugging the electrical connectors, unbolting the old unit, and installing the new one. Once installed, the vehicle’s computer systems will recognize the new, correctly programmed module, restoring proper communication and function to your transmission.
