8F35

The Ford 8F35 is an 8-speed electronically controlled automatic transmission developed for transverse-engine applications. It uses a conventional torque converter with lock-up clutch, planetary gearsets and electronically controlled hydraulic clutches, and is designed for front-wheel-drive and all-wheel-drive vehicles.

Specification: 8-speed automatic • Ford 8F35 • 8FMid family • Transverse installation • Front-wheel drive and AWD applications • Torque converter with lock-up clutch • Electronic-hydraulic control • Selectable one-way clutch • 4.689:1 first gear • 0.617:1 eighth gear • 2.960:1 reverse • Approximately 7.6:1 ratio spread • MERCON ULV / Ford WSS-M2C949-A transmission fluid • Approximately 11-litre dry-fill capacity on documented applications.

The 8F35 is used across selected Ford and Lincoln applications, including Ford Edge, Escape/Kuga, Focus, Maverick, Bronco Sport, S-MAX and Transit Connect, plus selected Lincoln applications. Exact fitment, final-drive ratio, valve body, calibration and internal components vary by application, so the VIN, complete transmission number, OEM gearbox code and individual component identification should always be confirmed before ordering replacement parts.

Common Faults

Common 8F35 problems include harsh or delayed shifting, shift flare, torque-converter clutch shudder, hydraulic/solenoid faults, valve-body problems and transmission calibration/adaptation issues. Symptoms can include hesitation during low-speed shifts, harsh engagement, erratic shifting, vibration or shudder and transmission warning messages.

Diagnosis should include manufacturer-specific fault codes, transmission software/calibration level, adaptive values, fluid level and condition, solenoid and valve-body operation and torque-converter clutch performance before internal mechanical components are replaced.
