What Does P076C Mean?
Shift Solenoid H is mechanically stuck in the on (energized) position. The TCM detects that the gear controlled by solenoid H remains engaged when it should be released. This can cause gear bind-up, inability to downshift properly, or the transmission remaining locked in an incorrect gear ratio.
Common Causes
35%
Shift solenoid H mechanically stuck open due to debris or internal spring failure
25%
Valve body shift valve stuck in the applied position in solenoid H circuit
20%
Short circuit in solenoid H wiring keeping the solenoid permanently energized
15%
Transmission fluid contamination preventing the solenoid valve from closing
5%
TCM driver circuit stuck on, continuously powering solenoid H
Diagnostic Steps
1
Verify in live data that the gear controlled by solenoid H remains engaged even when the TCM commands it off.
2
Disconnect solenoid H electrically and check if the stuck-on condition clears to differentiate electrical from mechanical causes.
3
Measure solenoid H resistance and test the circuit for a short to power.
4
Inspect the valve body for a stuck shift valve in the solenoid H hydraulic circuit.
5
Replace solenoid H and perform a transmission fluid service if contamination is found.
Estimated Repair Cost
$300 - $1,500
Parts + labor, varies by vehicle and location
Shift Solenoid H is mechanically stuck in the on (energized) position. The TCM detects that the gear controlled by solenoid H remains engaged when it should be released. This can cause gear bind-up, inability to downshift properly, or the transmission remaining locked in an incorrect gear ratio.
The most common cause of P076C (Shift Solenoid H Stuck On) is: Shift solenoid H mechanically stuck open due to debris or internal spring failure
Typical repair costs for P076C range from $300 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A stuck-on solenoid can cause gear bind-up or prevent proper downshifting, leading to unpredictable vehicle behavior. Minimize driving and go directly to a repair facility.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P076C to identify the root cause.
