Expert Insight: The Brains Behind the Brawn
Many drivers spend hundreds of dollars chasing what they believe are mechanical transmission problems, like faulty solenoids or sensors. However, on the 2003 Cadillac CTS, the TCM is often the true source of the issue. This module is the ‘brain’ that tells the transmission when and how to shift. When it fails, it sends incorrect signals, making a perfectly healthy transmission act erratically. By replacing the faulty 2003 Cadillac CTS TCM, you are addressing the root cause, not just the symptoms, ensuring a lasting and reliable fix.
