P0762: Shift solenoid C stuck on
Shift solenoid C stuck on
Severity: Severity not verified — if the car runs badly, have it inspected
The sources we read define the code and list causes but say nothing about whether you can keep driving, so we do not rate it. Owner complaints for this code describe harsh shifts, lost gears and a truck or car that would not move.
P0762 in short
P0762 means the transmission computer sees shift solenoid C stuck on, meaning it stays energized or open when it should not. The two causes the references list are the solenoid itself and its wiring. A scan tool that reads the transmission module is needed to tell them apart.
Shift solenoids are electrically controlled valves that direct fluid to change gears. P0762 is the generic code for solenoid C stuck on, and the Delaware DMV code list and TroubleCodes.net give the same title.
TroubleCodes.net lists wiring and the shift solenoid as the probable causes and says a basic code reader will not show transmission module data. Which gears solenoid C controls differs by transmission, so the maker's service information decides the exact symptom.
Some owners report internal damage found after the code set, such as metal in the fluid or a missing gear, but those are individual reports and not a ranked cause.
Most likely causes
These are general causes for this code across vehicles. None is specific to one make or model.
Cause 1: Wiring or connector fault at solenoid C
Common general cause- Why it ranks here
- TroubleCodes.net lists wiring first among the probable causes.
- What would change this
- Rises if the transmission harness or connector shows chafing, corrosion or fluid inside the plug. Falls if the circuit tests good.
Cause 2: Failed or stuck shift solenoid C
Common general cause- Why it ranks here
- The shift solenoid is the other probable cause TroubleCodes.net lists, and the code itself says the solenoid is stuck on.
- What would change this
- Rises if the wiring tests good and the solenoid fails a resistance or command test. Falls if a replaced solenoid does not clear the fault.
Cause 3: Internal transmission damage behind the code
Possible — needs testing- Why it ranks here
- Owner complaints describe gears missing or metal in the fluid after this code set, and one shop replaced the solenoid without restoring the gear. These are individual reports, so this ranks below the listed causes.
- What would change this
- Rises if the fluid carries metal or burnt debris or a gear is missing after the solenoid and wiring check out. Falls if the solenoid or wiring fix restores normal shifting.
What to test first
Start at step 1. Each result tells you what it means and where to go next.
Step 1: Read codes from the engine and transmission modules with a scan tool that supports both, before clearing anything. Note any other transmission codes stored with it.
IfOnly this code is stored
It meansInspect the wiring at the transmission next.
IfOther shift or pressure codes are stored too
It meansDiagnose the full set as one fault; internal damage becomes more likely.
Step 2: Inspect the transmission connector and harness for chafing, corrosion and fluid inside the plug.
IfDamage, corrosion or fluid in the connector is found
It meansRepair it and retest.
IfWiring looks sound
It meansHave the solenoid tested.
Step 3: Have a shop test solenoid C resistance and its command on a scan tool with bidirectional control, against the maker's specification.
Warning:The transmission fluid can be hot and the pan sits under the vehicle. Testing needs the maker's specifications and the vehicle safely supported; leave it to a shop.
IfResistance is out of range or the solenoid does not respond to commands
It meansThe solenoid has failed.
IfSolenoid and circuit are good
It meansLook for internal damage, starting with the fluid condition.
Symptoms
- Check engine light
- Hesitation when accelerating, reported by one owner with this code
- Harsh or wrong shifts Gets more serious: stop and have it checked.
How to fix
Step 1: Do not clear the code before the transmission module has been read.
Step 2: Have the transmission harness and connector checked before any part is replaced, since wiring is a listed cause.

P0762 questions
What is shift solenoid C?
It is one of the electrically controlled valves that route fluid to change gears. P0762 means the computer found it stuck on.
Can I drive with P0762?
We found no source that says. Owners with this code report harsh shifts, missing gears and cars that would not move, so have it read and inspected promptly.
