All 3 Known Issues
The 2000-2005 Ford Excursion equipped with the 6.8L V10 engine and BorgWarner 4405 electric-shift-on-the-fly transfer case experiences multiple failure modes including transfer case shift motor failure, false neutral conditions, and GEM (Generic Electronic Module) control issues. The electric shift motor can become stuck in intermediate positions between 2WD and 4WD, causing a false neutral condition where no drive torque reaches the wheels. The GEM module that controls 4WD engagement can fail or lose communication, preventing 4WD operation entirely. JustAnswer.com and Ford Expedition Forum document cases where the transfer case shifts to neutral unexpectedly. RepairPal estimates the transfer case shift motor replacement cost between $346 and $420, but complete transfer case overhaul or replacement can cost $3,000-5,000.
Common Symptoms
- Transfer case stuck between 2WD and 4WD (false neutral)
- 4WD indicator light flashing or not illuminating
- No response when shifting from 2H to 4H or 4L
- Grinding or clunking when engaging 4WD
- Vehicle loses all drive torque unexpectedly
- GEM module 4x4 fault codes
- Transfer case shift motor running but not completing shift
- Difficulty shifting from 4L back to 2H
How to Fix
Diagnose using GEM module DTCs first - many issues are electrical (shift motor or GEM) rather than mechanical. The shift motor (Dorman 600-805 or Motorcraft) is the most commonly replaced component at $200-350 plus 1-2 hours labor. If the GEM module has failed, replacement and programming ($300-600) is required at a dealer. For mechanical transfer case issues (grinding, worn chains), a complete rebuild ($2,000-3,500) or remanufactured replacement ($2,500-5,000 installed) is needed. Change transfer case fluid every 30,000 miles with Mercon V.
What Owners Are Using
Parts and tips from 680+ owners who fixed this issue
- TipMost V10 Excursion transfer case "failures" are actually the electric shift motor or GEM module, not the transfer case itself. Diagnose the electrical components first before authorizing expensive transfer case work. The shift motor is accessible without dropping the transfer case.
- NoteIf the transfer case drops to neutral at highway speed, you lose all drive torque instantly - this is a safety hazard. If you experience even one false neutral event, do not drive the vehicle until the transfer case system is diagnosed and repaired.
The 6.0L Powerstroke diesel (2003-2005 Excursion) is notorious for TTY head bolt stretching under boost pressure, causing head gasket failure. This is the same engine used in Super Duty trucks and is one of the most problematic diesel engines Ford produced.
Common Symptoms
- White smoke from exhaust
- Coolant loss
- Overheating
- Degas bottle overflow
- Rough running
How to Fix
The oil cooler on the 6.0L Powerstroke clogs with debris from deteriorating coolant, reducing cooling capacity and causing elevated oil and coolant temperatures. This leads to cascading failures including EGR cooler rupture and head gasket failure.
Common Symptoms
- High engine oil temperature
- Coolant temperature fluctuation
- EGR cooler failure
- Poor heater output
