What it means
P0767 is the generic code for Shift Solenoid D stuck on. The transmission control module has seen that the gear ratio or the solenoid's commanded state does not match what it expects, which suggests the solenoid or its valve is stuck in the energised or open position. Which gears and functions solenoid D controls depends on the make, model and gearbox.
Symptoms
- Gearbox stuck in one gear or in limp-home mode
- Harsh, delayed or flared gear changes
- Wrong gear selected or no upshift or downshift
- Gearbox warning light or engine light on
- Poor fuel economy or higher engine revs at cruise
Possible causes
- Shift solenoid D sticking due to contamination or varnish in the valve bodylikely
- Low, dirty or degraded transmission fluidlikely
- Damaged wiring, poor connector contact or a short to power or earth in the solenoid circuitpossible
- Worn valve body, blocked fluid passage or internal hydraulic leakpossible
- Faulty transmission control module or driver circuitrare
- Outdated transmission control software where the manufacturer lists it as a known cause for the modelrare
How to diagnose
- Read all stored and pending codes and the freeze frame data, noting gear, speed, fluid temperature and load when the fault set
- Check the transmission fluid level, condition and smell using the manufacturer's procedure, as the correct method varies by model
- Inspect the gearbox wiring harness and connector for chafing, fluid ingress, corrosion and bent or pushed-out pins
- Check the solenoid circuit for correct resistance, supply, earth and short circuits using the manufacturer's wiring diagram
- Use a scan tool's live data and actuator tests to compare the commanded solenoid state with the actual gear ratio and operation
- Check the battery condition and charging voltage, as low voltage can cause false shift faults
- Look for relevant technical service bulletins or software updates for the vehicle and gearbox
- If electrical checks pass, test the solenoid and inspect the valve body following the manufacturer's procedure
How to fix
- Correct the fluid level or replace the fluid and filter with the specified type, if the fluid is the cause
- Repair or replace damaged wiring and connectors in the solenoid circuit
- Replace the faulty shift solenoid D or the solenoid pack as the manufacturer specifies
- Clean, repair or replace the valve body if it is sticking or worn
- Apply an official transmission software update if one is available and applicable to the fault
- Repair or replace the transmission control module only after wiring and solenoid faults are ruled out
Can I keep driving?
Medium severity
The car may be driveable in limp-home mode, but continued driving with a stuck solenoid can overheat and damage the gearbox. Get it checked soon and avoid heavy loads, towing and long journeys until it is fixed.
