The P2702 fault code indicates an issue with the transmission friction element 'C' apply time range or performance. This code is often triggered when the Engine Control Module (ECM) detects that the apply time for the friction element is outside of the manufacturer’s specified range. Proper operation of the friction elements is crucial for smooth gear transitions and overall vehicle performance.

What are the symptoms of the P2702 code?

Signs that may accompany the P2702 code include:

• Harsh or erratic shifting, particularly during acceleration or deceleration.
• Slipping gears or delayed engagement when shifting.
• Unusual noises from the transmission, such as grinding or whining sounds.
• Warning lights illuminated on the dashboard, including the check engine light.

What causes the P2702 code?

Common causes of the P2702 code include:

• Faulty transmission control module or ECM.
• Wiring issues, such as damaged or corroded connectors.
• Low transmission fluid levels or degraded fluid condition.
• Malfunctioning solenoids that control the application of the friction elements.
• Internal transmission problems, such as worn clutches or seals.

How to fix P2702?

To resolve the P2702 fault code, follow these steps:

• Inspect all wiring and connectors related to the transmission for damage or corrosion. Repair as necessary.
• Check the transmission fluid level and condition; replace the fluid or top it off if low.
• Test the transmission control module and replace if faulty.
• Examine the solenoids and replace any that are malfunctioning.
• If internal components are worn or damaged, a transmission rebuild or replacement may be necessary.
