Case Study: A Tricky Diagnosis
A customer brought in their ’08 Cadillac DTS with classic transmission complaints: harsh 1-2 shifts and occasionally getting stuck in 3rd gear (limp mode). The check engine light was on with a P0700 (Transmission Control System Malfunction) code. Another shop had quoted them over $3,000 for a transmission rebuild, assuming internal mechanical failure. After a quick scan and data stream analysis in my bay, I saw erratic solenoid command signals. I knew this was likely electronic, not mechanical. We installed one of our VIN-programmed T42 modules, and in under an hour, the car was shifting like it just left the factory. The customer saved thousands and avoided an unnecessary major repair, all thanks to correctly diagnosing the root cause: a faulty 2006-2011 DTS TCM.

A Straightforward Guide to Installation
