P0765 — Shift Solenoid D

P0765: Shift Solenoid D — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

Shift Solenoid D. Basic catalogue definition; diagnostic details have not yet been reviewed.

Affected system: Powertrain

Symptoms

  • A transmission warning, delayed changes or unexpected gear behavior may occur.
  • The code describes shift solenoid D control malfunction; it cannot alone establish a failed solenoid.

Possible causes

  • Low or contaminated transmission fluid, valve-body restrictions or a solenoid problem may interfere with gear selection.
  • Faulty wiring or connectors may also contribute; their role depends on gearbox design.

What to check

  • Read P0765 with accompanying transmission codes and freeze-frame data.
  • Check fluid level and condition using the manufacturer-specified method; inspect connectors and harness.
  • Compare requested versus actual shifting or solenoid operation with compatible equipment before replacement.

Also written as: P0765-00, P076500, PO765 (some scan tools add the fault-type byte, e.g. -00).
