What it means

P0760 is the generic code for a fault in the Shift Solenoid C circuit or its performance. The transmission control unit commands the solenoid and monitors its circuit, and sets the code when it sees an electrical fault or when the resulting gear ratio does not match the gear it requested. Which gears Solenoid C controls varies by transmission, so the exact effect depends on the model.

Symptoms

  • Harsh, delayed or flared gear changes
  • Transmission stuck in one gear (limp mode)
  • Gearbox warning light or malfunction indicator lamp on
  • Incorrect gear selection or missing a gear
  • Poor fuel economy or engine revving high for the speed
  • Transmission slipping under load

Possible causes

  • Faulty shift solenoid C (stuck, worn or open/short circuit internally)likely
  • Damaged wiring or poor connector contact between the solenoid and the transmission control unit, including internal harness chafinglikely
  • Low, degraded or contaminated transmission fluidlikely
  • Blocked valve body passages or debris/clutch material restricting the solenoidpossible
  • Worn clutches or internal hydraulic faults causing the gear ratio to disagree with the commanded gearpossible
  • Low battery voltage or poor earth affecting solenoid operationpossible
  • Faulty transmission control unit or outdated software calibration, where a known update exists for the modelrare

How to diagnose

  1. Read all stored and pending codes and the freeze frame data, noting gear commanded, vehicle speed and fluid temperature when the code set.
  2. Check the transmission fluid level and condition (colour, smell, debris) following the manufacturer's procedure for the model, as some transmissions are sealed.
  3. Inspect the wiring and connector to the transmission for damage, corrosion, fluid ingress or chafing.
  4. Check battery condition and charging voltage, and inspect the power and earth connections to the control unit.
  5. Measure the resistance of the Solenoid C circuit and check for shorts to earth or voltage against the manufacturer's specification.
  6. Use live data or an actuator test to command the solenoid and confirm it responds, and compare the commanded and actual gear ratio.
  7. Check for any manufacturer technical bulletins or software updates relating to the code for that model.
  8. If the electrics are sound, inspect the pan for debris and assess the valve body and internal clutches.

How to fix

  • Repair or replace damaged wiring and connectors serving the solenoid.
  • Replace the faulty shift solenoid C, or the solenoid pack where it is supplied as an assembly.
  • Correct the fluid level and renew degraded fluid and filter using the specified fluid for the transmission.
  • Clean or overhaul the valve body, or repair worn internal components if mechanical wear is confirmed.
  • Repair battery or earth faults to restore stable supply voltage.
  • Update the transmission control unit software only where a known update covers this fault, or replace the unit if proven faulty.

Can I keep driving?

Medium severity

The car may be driven carefully a short distance to a workshop, but avoid heavy loads and towing. Continued use with slipping or limp mode can cause expensive internal transmission damage, so have it checked soon.
