Ford Fiesta Durashift Clutch Actuator Rebuild. This Ford Fiesta (Mk6) clutch actuator is fitted to the Durashift EST (Electronic Shift Transmission) gearbox and is very problematic. Common internal failure of this actuator will cause the gearbox to get stuck in a gear, and when you turn the car off and then try to restart you will find that the engine refuses to start, this is because the gearbox actuator cannot select neutral.
