- How the car detects it
- P2705 covers the sixth friction element, F, so only transmissions with at least six shift elements use it, such as Ford's ten-speed and eight-speed families. The controller has found that F applies outside the time it has learned. Ford's SSM 50617 for Edge ST and Nautilus models from 2020 to 2022 with the 8F57 built up to 18 March 2022 reports cars returning to Park when drive or reverse is selected; the main code is P2707, and P2705 may accompany it. The cause is the F clutch piston, which serves second and eighth gear and whose rubber sealing surface can be damaged. On the 10R140, TSB 20-2375 includes P2705 among the codes from sticking main control valves and lets all six clutches be cycled. Roush's propane Ford chassis store P2705 without MIL.
