P2701 Transmission Friction Element B Apply Time Range/Performance

P2701 concerns friction element B: the controller has measured an apply time for this clutch or brake that falls outside its learned window. The letter is assigned per gearbox, and bulletins show how varied the causes are. Ford's SSM 47361 pairs P2701 with P0757 on the 2018 Mustang 10R80 when it will not shift beyond second gear and traces it to one-way clutch damage in the front support. On 6F50/6F55 units built from November 2015 to February 2016, SSM 46069 and 50861 combine it with P0756 and loss of reverse, third and fifth gear, caused by a displaced direct clutch snap ring. A 2023 Stellantis case for Ram Heavy Duty trucks links P2701 and harsh shifts to a dislodged 2C clutch snap ring. Expect harsh shifts, flare or a missing gear.

Likely causes

Mechanical damage in clutch B, such as a displaced snap ring or damaged hub
Damaged one-way clutch working together with element B
Sticking valve or pressure control solenoid for clutch B
Low or contaminated transmission fluid

Symptoms

  • Harsh shifts or engine flare during shifts
  • One or more gears missing, e.g. no upshift beyond second
  • Warning light on
