P2702: Transmission Friction Element C Apply Time Range/Performance
The time required to apply friction element C is outside the expected window. Worn clutch, low pressure, or sticky valve.
What P2702 means
P2702 is a generic OBD-II powertrain code in the transmission group. In plain English: the signal is within electrical limits but doesn’t make sense compared with other readings, so the part or system isn’t performing as expected.

Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Common causes
- 01Worn clutch friction platesMost likely
- 02Pressure control solenoid driftPossible
- 03Internal hydraulic leak in apply circuitPossible
Can I drive with P2702?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P2702
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P2702. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Check for related codes first
Look for P2701, P2703, P2700, P2704. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Friction element C, Hydraulic control unit, Pressure control solenoid) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Worn clutch friction plates; pressure control solenoid drift; internal hydraulic leak in apply circuit. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P2702 FAQ
What does P2702 mean?
P2702 means “Transmission Friction Element C Apply Time Range/Performance”. The time required to apply friction element C is outside the expected window. Worn clutch, low pressure, or sticky valve.
Is P2702 serious? Can I keep driving?
We rate P2702 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P2702?
The most common causes, from most to least likely: Worn clutch friction plates; Pressure control solenoid drift; Internal hydraulic leak in apply circuit. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P2702?
Typical labor is about $375–$1,250 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P2702 myself?
DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P2702 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
