Note: The Ford Fiesta was discontinued in North America after 2019, so a 2023 model would be a European market vehicle. The DPS6 dual-clutch transmission in Fiesta shares the same problematic design as the Focus, with complete transmission failures representing the worst-case scenario for this troubled system.
Signs of Impending Failure
Complete DPS6 failure usually follows warning signs that escalate over time. What starts as mild shudder progresses to severe shaking. Grinding noises during shifts indicate mechanical damage. The transmission may start slipping out of gear or refusing to engage certain gears. When the P0700 code appears with multiple supporting codes, the transmission may be near complete failure.
What Fails in the DPS6
Several components can fail catastrophically. The clutch fork mechanism that actuates the clutches can break, leaving the transmission unable to engage. The input shaft seal leaking causes clutch contamination and rapid wear. The mechatronic unit (TCM combined with hydraulics) can fail electronically or mechanically. Internal gear damage from operating with worn clutches causes grinding and inability to shift.
Diagnostic Approach
When P0700 appears with a Fiesta DPS6, comprehensive diagnosis is essential before recommending repairs. Multiple fault codes usually accompany complete failure—documenting all codes helps identify root cause. Physical inspection for leaks, noises, and external damage provides additional information. In many cases, internal inspection or replacement is the only path forward.
Repair vs. Replace Decision
Complete DPS6 failure often makes replacement more economical than repair. Remanufactured units with updated components offer improved reliability. Complete clutch and mechatronic replacement during extensive repairs may approach replacement cost. Consider the vehicle's overall value when making repair decisions.
