P0760: Shift Solenoid ‘C’ DTC Trouble Code

In order to propel you down the road, an automatic transmission has to channel pressurized transmission fluid to move the right gears around. The shift solenoid is responsible for moving the valves that direct the fluid. If one of them is not functioning correctly, then a P0760 diagnostic trouble code will be stored.

How Serious is the Code?

While a P0760 DTC might not be accompanied by immediate transmission problems, they can progress quickly. So you will need to have a mechanic diagnose the source of the problem.

Symptoms

Symptoms of a P0760 include:

• Check engine light
• Limp mode
• Delayed, harsh or erratic shifts
• Slipping through the gears
• Engine stalling
• Getting ‘stuck’ in a gear
• Vehicle won’t move when in gear
• Decreased fuel economy
• Transmission overheats

Causes

• Low transmission fluid level
• Dirty transmission fluid / filter
• Damaged wiring/connector
• Faulty solenoid
• Faulty transmission pump
• Internal pressure issue
• Valve body issue
• ECU or TCM failure

How to Diagnose the Code?

Many times, poor maintenance and dirty transmission fluid can lead to problems with the shift solenoids. To rule this out, a mechanic should first check the level and condition of the transmission fluid. If metal fragments are visible in the fluid, a rebuilt or remanufactured transmission may be required. If the fluid doesn’t appear to be “burnt”, then flushing the transmission may clear blocked internal passages.

Should no problems be found with the ATF, the wiring and connectors should be inspected for damage, corrosion and possible short circuits. If everything appears to be in good condition, then the solenoid will have to be tested according to the manufacturer’s recommended procedure. If no problems are found with the solenoid, then the transmission pump, valve body or pressure regulator could be suspected.

Common Mistakes When Diagnosing

It’s not uncommon to assume that the solenoid has failed, when in reality it was a wiring issue, or the solenoid wasn’t tested correctly. Dirty transmission fluid could also clog an internal passage, making it appear to be a failed shift solenoid.

What Repairs Will Fix P0760?

• Change the transmission fluid and filter
• Replace failed shift solenoid
• Replace or repair failed transmission pump
• Repair or replace transmission valve body
• Perform a transmission flush to clear passages
• Repair or replace damaged wiring
• Clean corrosion from connectors
• Flashing or replacing PCM/TCM
• Install a rebuilt or remanufactured transmission
