P072F: Stuck in Gear 4

Standardized SAE J2012 code · P07xx — Transmission

What does P072F mean?

Ford's DPS6 dry dual-clutch transmission moves its gears with two electrically driven shift drums whose position is read by Hall sensors: drum A shifts 1st, 3rd and 5th, drum B reverse, 2nd, 4th and 6th. Ford's 2012 summary lists 'stuck in gear' codes for each drum: the module commands the drum out of a gear, but the gear stays engaged. It gives no thresholds or MIL rating. P072F is the code for drum B: fourth gear cannot be disengaged. The car stays in fourth or sub-gearbox B is locked out. Slip in fourth gear is P0734.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

  • Transmission stays in one gear, no further shifts
  • Limp mode, transmission warning
  • Clunking or blocking when shifting

Common causes

  • Medium Shift fork or synchronizer for this gear sticking
  • Medium Shift drum B motor, Hall position sensing or driver faulty
  • Low Transmission module
  • Low On planetary automatics: clutch or brake not releasing (sticking valve)

Likelihood is a general estimate across vehicles; your make and model may differ.
