About the 8F35
The Ford 8F35 was introduced for the 2019 model year. It is an eight speed front wheel drive or all-wheel drive transmission, co-engineered with the GM 9T50.
It uses a four element torque converter with an internal clutch, four planetary gear sets, a hydraulically operated Selectable One-Way Clutch and five friction elements. The main control valve body contains eight solenoids and, new for Ford, a pressure switch assembly. The PCM uses a unique control strategy for the CIDAS style solenoids, while the TCC and line pressure solenoids are more conventional variable force motors.
Vehicles with the 8F35 use an external Powertrain Control Module for eight forward speeds and one reverse, lockup control, shift timing and shift feel, using inputs from several sensors, some shared with the engine control system. The transmission is cooled by an external oil to coolant cooler that controls flow thermostatically.
Notes
These solenoids are pulse width modulated but do not have fluid flowing through them.
The 8F35 is also available with an engine stop/start feature that uses line pressure to charge two internal drive elements to ensure the vehicle will not delay on initial take-off during an auto-start-stop event.
