Ford Five Hundred · 2005–2007
The Ford Five Hundred equipped with the CVT (Continuously Variable Transmission) suffers from chronic shuddering, slipping, and premature failure. The CVT transmission bucks and shakes when decelerating or accelerating around 25 MPH, and the problem worsens as the transmission heats up. Many owners report the transmission slipping under acceleration, loss of reverse gear, and complete transmission failure at 80,000-120,000 miles. The CVT was supplied by ZF and proved unreliable in the Five Hundred application. Cold weather exacerbates the issues, with the CVT fluid thickening and causing delayed engagement and sluggish acceleration. Replacement transmissions are difficult to source as the supplier no longer manufactures new units.
Common Symptoms
- Shuddering or bucking when accelerating or decelerating around 25 MPH
- Transmission slipping — RPMs rise without corresponding acceleration
- Delayed engagement when shifting from Park to Drive or Reverse
- Loss of reverse gear while forward gears still work
- Check engine light with transmission codes P0700 or P0701
- Sluggish acceleration especially in cold weather
- Whining noise from transmission area
How to Fix
Change the CVT fluid every 30,000 miles using the correct CVT-specific fluid (NOT standard ATF). Have the speed sensors and solenoids tested if shuddering occurs — replacing a $100 sensor is preferable to a $5,000 transmission. If the transmission fails, rebuilt CVT units are available from specialty transmission shops for $3,000-$4,500 installed. Some owners have converted to a conventional 6-speed automatic from a Ford Taurus, though this requires significant modification ($3,000-$5,000).

Frequently asked questions
What does P0701 mean?
P0701 stands for "Transmission Control System Range/Performance." This code indicates the transmission control system has a range or performance problem — the computer detected that some monitored aspect of transmission operation is outside the expected window. It's a fairly general transmission code that often appears alongside more specific solenoid, pressure, or shift codes that pinpoint the actual fault. When the control system's self-monitoring sees readings or behavior that don't match commanded operation, P0701 sets. Symptoms can include harsh or erratic shifts, slipping, or the transmission entering a protective limp mode.
What are the most common causes of P0701?
The most common causes of P0701 are: Low or degraded transmission fluid, Faulty shift or pressure control solenoid, Worn valve body or internal hydraulic fault, Wiring or connector problems in the transmission circuit, Internal clutch/band wear causing slipping, Faulty transmission speed or pressure sensor, Software needing an update or recalibration, Faulty transmission control module (rare). The specific cause varies by vehicle.
How much does it cost to fix P0701?
Repair costs for P0701 range from $200 to $5,000, depending on the vehicle and root cause.
