What Does P076B Mean?
Shift Solenoid H is performing outside its expected range or is mechanically stuck in the off position. The TCM commands solenoid H to engage, but the expected gear ratio change does not occur. This affects the specific gear application controlled by solenoid H in multi-speed transmissions, resulting in missed shifts or gear slippage.
Common Causes
35%
Shift solenoid H stuck in the off position due to debris or internal failure
25%
Valve body bore wear preventing solenoid H from actuating the shift valve
20%
Contaminated transmission fluid clogging solenoid H fluid passages
15%
Internal clutch pack or band wear for the gear controlled by solenoid H
5%
Insufficient solenoid current due to wiring resistance
Diagnostic Steps
1
Monitor commanded vs. actual gear ratios in live data to confirm solenoid H is not producing the expected gear engagement.
2
Check transmission fluid level and quality — contaminated or low fluid directly impacts solenoid performance.
3
Measure solenoid H resistance and compare to the manufacturer specification.
4
Command solenoid H on/off with a bi-directional scan tool to test for proper actuation.
5
If solenoid tests pass, perform a transmission pressure test to isolate the hydraulic circuit controlled by solenoid H.

The most common cause of P076B (Shift Solenoid H Performance/Stuck Off) is: Shift solenoid H stuck in the off position due to debris or internal failure
Typical repair costs for P076B range from $300 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle may not access all gear ratios. Limited low-speed driving is acceptable, but highway driving may not be possible if higher gears are affected. Seek repair promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P076B to identify the root cause.
