What P0768 means
A shift solenoid is an electrically switched valve in the valve body. Manufacturers use these codes differently: Ford reports an open circuit with the base code and shorts separately, and the letter is not tied to a valve number (Saab's Aisin 9-5: C = valve S4, D = valve S5). P0768 is the collective electrical code for solenoid D. GM's 2006 Allison tables flag a driver hardware fault for more than 0.1 s, after one trip; Saab's Aisin 5-speed (valve S5) checks current draw and enters limp mode with 'check gearbox'; Hyundai's 8-speed uses it for the valve of the 4 & overdrive clutch and replaces valve and electronic module, then the module if it returns. Ford does not use P0768.
P0768 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0768
- Check engine or transmission warning lamp
- Limp mode in a fixed gear (Ford: fifth with maximum pressure)
- Harsh shifts
Common causes of P0768
- Most likelyOpen or corroded wire, connector or internal harness
- PossibleSolenoid coil open or shorted
- Less likelySolenoid supply (high-side switch) missing
- Less likelyModule driver faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0768 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 68 | The exact fault in that area. |
What to do next
- Note P0768 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0768
What does P0768 mean?
P0768 means "Shift Solenoid D Electrical". A shift solenoid is an electrically switched valve in the valve body. It is a generic code, so it means the same on every make.
Is it safe to drive with P0768?
Drive gently and only to a workshop. With P0768 the car can go into limp mode (reduced power) to protect itself.
Will P0768 fail an emissions test?
Yes, it can. P0768 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0768 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0768 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
