P073C Stuck in Gear 7

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. P073C would be the code for a seventh gear that cannot be disengaged, which only exists on transmissions with seven or more gears. No manufacturer document available to us uses it – the six-speed DPS6 has no seventh gear, GM's 9- and 10-speeds report clutch valve codes and Ford's 10R80 solenoid codes instead. Slip in seventh gear is P076F.

Likely causes

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

Symptoms

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