P0768: Shift Solenoid D Electrical
Quick Answer
Safe to drive (short-term)
P0768 means the transmission control module found an electrical fault in the circuit of shift solenoid D, one of the valves that direct fluid to change gears. The fault can be an open circuit, a short or a resistance outside its range, in the solenoid coil or its wiring. Which gear changes solenoid D handles depends on the gearbox design, so the repair steps differ by transmission. It is a generic code for conventional automatics.

A scan needs a Bluetooth OBD2 adapter (Bluetooth LE on iPhone), about €25-60; the built-in demo runs without one. See which adapter to buy
What does P0768 mean?
P0768 is a transmission-related diagnostic trouble code classified as moderate severity.
What are the symptoms of P0768?
- Check engine light on
- Harsh, jerky or delayed shifts
- A gear missing, or a gear change skipped
- Pulling away in a higher gear than normal
- Limp mode, with the gearbox held in one gear
- Higher engine revs at a steady speed
What causes P0768?

Low, burnt or contaminated transmission fluid damaging the solenoids
: medium
Worn or blocked valve body
: low
Fault in the transmission control module output (rare)
: low
Is it safe to drive with P0768?
Generally yes, for short-term driving. Short, gentle driving is usually possible, but the gearbox may shift harshly, skip a gear or drop into limp mode. Do not keep driving on it for weeks: wrong-gear operation wears the clutch packs, and burnt fluid can damage the other solenoids. Have it diagnosed soon, and stop if the car will not select a gear.
How do you diagnose P0768?
- Read all stored codes and the freeze frame. Other solenoid codes, speed sensor codes or P0700 stored with P0768 change where to look.
- Check the transmission fluid level and condition where the car has a dipstick. Dark, burnt-smelling fluid points to internal wear and to damaged solenoids.
- Inspect the connector on the gearbox and the wiring to it for corrosion, rubbing and fluid wicking into the plug.
- Measure the solenoid's resistance against the workshop specification for that gearbox. Specifications vary a lot by transmission, so a general figure is not a safe guide. An open reading or one near zero points at the coil or its internal wiring.
- Check the wiring between the solenoid connector and the control module for continuity and a short to ground or voltage, with the plugs disconnected.
- Find which gear change solenoid D controls on this gearbox from the service information, since the label does not mean the same thing on every transmission.
- A generic OBD2 reader shows P0768 and the freeze frame but cannot command the solenoid or read gearbox-specific data. If wiring and solenoid pass, the valve body or control module is next, and that needs manufacturer-level diagnosis.
How much does P0768 cost to fix?
| Repair | Parts Cost | Labor Cost | Total Estimate | DIY Difficulty |

| Replace a single shift solenoid | €40–€200 | €100–€350 | €140–€550 | Professional |
| Replace the solenoid pack (where solenoid D is not sold alone) | €150–€500 | €200–€500 | €350–€1000 | Professional |
| Valve body replacement or repair | €200–€800 | €300–€700 | €500–€1500 | Professional |
| Replace the transmission control module and program it | €300–€1000 | €150–€350 | €450–€1350 | Professional |

Common questions about P0768
- What does P0768 mean?
- P0768 means the transmission control module found an electrical fault in the circuit of shift solenoid D. Shift solenoids direct fluid inside the gearbox to change gears, and D is a letter label for one of them.
- Which gear is solenoid D?
- It depends on the gearbox. The letter is a label, and different transmissions map their solenoids to different gear changes, so the affected gear varies. Service information for your gearbox gives the mapping.
- Can I drive with P0768?
- Short, gentle trips are usually possible, but shifts may be harsh or a gear may be missing, and limp mode is a protection mode, not a fix. Do not keep driving on it for long, because wrong-gear operation wears the clutches.
- Is P0768 the solenoid or the wiring?
- Either. The solenoid coil is the most commonly listed cause, and the wiring and the pass-through connector into the gearbox come next. Check the connector and measure the solenoid before replacing parts.
- Will a fluid change fix P0768?
- Sometimes it helps, since low or burnt fluid can damage solenoids, but a coil that is open or shorted will not recover. Fix the fluid problem as well, or the new part can fail again.
- Can a generic OBD2 reader or phone app fix P0768?
- It can read and clear the code. It cannot command the solenoid or read gearbox data on most cars, so it only points you in the right direction.
