P0768: Shift Solenoid D Electrical
What to do
Expect a fixed gear. On a sealed mechatronic unit the individual solenoid cannot be measured externally, so this code carries more diagnostic weight than the equivalent on an older gearbox.
What this code means
A measurable electrical fault in solenoid D's circuit. On transmissions using an integrated mechatronic unit the individual solenoid windings may not be accessible for measurement from outside, which changes the diagnostic approach — the module's own current monitoring becomes the primary evidence rather than a meter, and that is a reason to trust the code more than usual rather than less.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
