P2702: Transmission Friction Element C Apply Time Range/Performance

With P2702 the transmission controller reports that friction element C does not engage within the time it expects, measured from the shift command to the moment the speed ratio changes. Which clutch C stands for differs between gearbox designs. Ford names the code in several valve body bulletins. For 10R140 units in 2020 F-Super Duty trucks, TSB 20-2375 lists P2700 to P2705 among codes caused by sticking main control valves; below 8,000 km the dealer runs a break-in routine three times on the affected clutches, beyond that the valve body is replaced. SSM 54595 for 8F35 units in 2025 Maverick, Corsair, Escape and Bronco Sport built from September 2024 to September 2025 reports P2702 with P2706 and P2707 when the vehicle will not leave Park. Roush propane chassis store it without MIL.

Symptoms

• Harsh or delayed shifts on gears using clutch C
• Vehicle may not shift out of Park on some Ford 8F35 units
• Wrench or engine warning light on

Most likely causes

• Sticking valves in the main control valve body
• Worn clutch C plates or leaking piston seals
• Low or contaminated transmission fluid
• Outdated transmission software or lost adaptive values

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the fluid level and condition
2. Compare the reading with other engine data while varying the engine speed.
3. Read the input and output speed in live data
4. Check the connector and wiring
5. Check for other related engine codes
6. Consult the manufacturer's procedure for the transmission

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P2702 means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• 7: Transmission
• 02: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2702?

Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.

What causes code P2702?

The most common causes are: sticking valves in the main control valve body; worn clutch C plates or leaking piston seals; low or contaminated transmission fluid.
