Transmission

P0762 — Shift Solenoid D Electrical Fault

Severity: medium Drive with care, to a shop

What P0762 means

The transmission control module (TCM) energizes shift solenoid D, which directs fluid through the valve body to apply and release clutches at the right time. P0762 sets when the electrical readings in that solenoid circuit fall outside the expected range, typically an open or a short. The result can be incorrect shifts and the transmission going into limp mode.

Symptoms

  • Harsh or missed shifts
  • Transmission limp mode
  • Slipping between gears
  • Check Engine light on
  • Stuck in one gear

Possible causes

  1. Failed shift solenoid D
  2. Dirty or burnt transmission fluid clogging the solenoid
  3. Valve body wear or debris
  4. Damaged wiring or corroded connector at the transmission
  5. Faulty driver circuit inside the TCM

How to diagnose

  1. Scan all codes and freeze-frame data and look for other transmission codes
  2. Check ATF level and condition: color, smell, metal particles
  3. Inspect the harness and transmission connector for chafing, moisture, and corrosion
  4. Test the solenoid circuit for opens, shorts to ground, and shorts to power
  5. Measure solenoid resistance and compare it to the factory spec
  6. Verify the TCM command signal with a scope or meter
  7. Drop the pan and inspect the magnet and valve body for debris and wear

Common fixes

  • Repair the wiring or replace the connector
  • Replace shift solenoid D
  • Change the ATF and filter
  • Clean or repair the valve body
  • Repair or replace the TCM if the driver is faulty

Questions and answers

What does P0762 mean?

It's an electrical fault in the shift solenoid D circuit of an automatic transmission. The control module sees an open or short and may switch to limp mode.

Can I drive with P0762?

Only briefly and carefully, to a shop. The transmission may stay in one gear, and slipping damages the clutches, so get it diagnosed soon.

Will changing the fluid fix P0762?

Sometimes, if debris is sticking the solenoid, but wiring or the solenoid itself is more common. Check the circuit and resistance first, then decide on replacement.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
