πŸ”§ Ford DPS6 / PowerShift TCM Failure – Control Module Faults Explained

Many Ford vehicles fitted with the DPS6 PowerShift (6DCT250) gearbox β€” especially certain Fiesta and Focus models β€” commonly experience Transmission Control Module (TCM) failures. At The Vehicle Check (0203 489 2610), we regularly diagnose these faults, which often lead to shuddering, hesitation, and loss of drive.

⚠️ Common Symptoms of DPS6 / PowerShift TCM Failure

  • πŸ’₯ Jerking or shuddering on take-off, especially in stop-start driving.

  • ⏳ Delayed or harsh gear changes, sometimes with hesitation before engaging a gear.

  • βš™οΈ Transmission slipping or dropping into neutral during acceleration.

  • 🚫 Intermittent no-start or sudden loss of power, often with warning lights present.

  • πŸ” Flashing gear selector or transmission warning messages on the dashboard.

πŸ” What Causes These TCM Problems

  • πŸ”Œ Internal electronic failure inside the TCM, a known weakness on DPS6 units.

  • πŸ”₯ Overheating, caused by the dry-clutch design and repeated low-speed driving.

  • πŸ›’οΈ Clutch contamination from leaking seals, affecting both the clutch packs and the control module.

  • 🧩 Design limitations, where heat, dust, vibration and electrical stress degrade components over time.

πŸ”„ Rebuild vs Replacement – What’s Best?

At The Vehicle Check, a rebuild is usually the most reliable and cost-effective solution. Replacing the module often results in the same faults returning because replacement units use the same vulnerable components.
