PCM

The Powertrain Control Module (PCM) controls both engine and transmission systems in many modern vehicles. When it fails, the car may lose power, shift incorrectly or refuse to start. Swedish Experts provides complete PCM repair, diagnostics, PCM replacement and full programming for American, Japanese and global vehicle brands.

Whether you drive a Jeep, Ford, Dodge, Chevy, Cadillac, Mazda, Nissan or Honda, our technicians diagnose PCM faults accurately and recommend the safest, most cost-effective solution—restoration or full module replacement with proper programming.

Our PCM Repair Services

PCM Diagnostics	PCM Repair & Restoration	PCM Replacement & Programming
Before any PCM repair, we run advanced diagnostics: fault-code scanning, communication tests, power/ground verification, wiring checks and live-data analysis to confirm whether the PCM is truly failing. Crucial for vehicles with random errors, shifting issues or no-start conditions.	When possible, we perform component-level PCM repair, including circuit restoration, connector refurbishment and internal fault correction. Each unit is bench-tested and validated before reinstallation. A cost-effective option compared to full module replacement.	If the PCM is beyond repair, we provide correct PCM replacement followed by full programming, VIN coding, immobilizer matching and transmission adaptation so the vehicle runs exactly as designed. Ideal for heavily damaged or water-exposed control units.
