What Does P076D Mean?
The electrical circuit for Shift Solenoid H has a fault. The TCM detects an open circuit, short to ground, or short to battery voltage in the solenoid H wiring. This is a purely electrical diagnosis indicating the solenoid cannot be properly driven, preventing the associated gear from engaging or disengaging correctly.
Common Causes
35%
Open or short circuit in the solenoid H wiring harness
30%
Shift solenoid H internal coil failure with open or shorted windings
20%
Corroded or damaged transmission connector causing circuit failure
10%
TCM solenoid driver circuit failure for solenoid H
5%
Ground circuit fault for the solenoid pack
Diagnostic Steps
1
Measure solenoid H resistance at the transmission connector — an open reading or near-zero resistance indicates coil failure.
2
Check for TCM drive voltage at the solenoid H pins with the key on to verify the TCM is outputting a signal.
3
Inspect the external transmission harness connector for corrosion, bent pins, or fluid contamination.
4
Perform continuity and short-to-ground tests on each wire in the solenoid H circuit from TCM to transmission.
5
If wiring passes and solenoid resistance is out of spec, replace shift solenoid H.

The most common cause of P076D (Shift Solenoid H Electrical) is: Open or short circuit in the solenoid H wiring harness
Typical repair costs for P076D range from $200 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Expect limp mode operation. Driving at reduced speed to a repair shop is generally safe, but normal driving should be avoided until the electrical fault is resolved.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P076D to identify the root cause.
