P0768
Shift Solenoid D Electrical
Transmission / shift controls
Generic OBD-II
Medium
What it means
P0768 means the transmission control module detected an electrical fault — a short or open — in the shift solenoid D circuit. Because that solenoid helps route hydraulic pressure for gear changes, shifting can turn harsh or the transmission may lock into limp mode. The problem is usually the solenoid itself or its wiring rather than internal transmission damage.

Can I keep driving? Usually drivable, but shifts may be harsh or the transmission may lock into limp mode — get it fixed to avoid added wear.
Common symptoms
What you'll notice
- Harsh or delayed shifting
- Transmission stuck in one gear (limp mode)
- Slipping feel during shifts
- Check-engine light on
Common causes
Most likely first
- Shorted or open shift solenoid D windingLikely
- Damaged wiring or connector in the solenoid D circuitCommon
- Loose or corroded electrical connectionsCommon
- Low or dirty transmission fluidLess often
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check for other transmission codes.
- Inspect the shift solenoid D connector and wiring for shorts, opens, or corrosion.
- Measure solenoid D resistance and compare to the specification.
- Check transmission fluid level and condition.
- Replace the solenoid if out of spec; evaluate the TCM last. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0768?+
For short trips usually, but the transmission may shift harshly or drop into limp mode. Repair it soon so you don't add wear driving in a fixed gear.
Can I just clear P0768?+
It returns quickly — an electrical fault in the solenoid circuit is detected on every drive cycle until repaired.
