What are the reasons why the gear button of Hummer H2 cannot be pressed?
1 Answers
There are several reasons why the gear button of Hummer H2 cannot be pressed: Solenoid valve damage: It is caused by the solenoid valve. There is a small valve core inside the solenoid valve that works by current, similar to the working valve in the valve body. This leads to unstable oil pressure regulation and uneven switching. Mechanical failure: Mechanical failure caused by internal wear of the transmission. Brake clutch: Slippage caused by brake clutch pressure leakage, and abnormal data reading caused by the sensor. Computer board failure: Problems with the sensor and computer board can cause the transmission to lock gears. Restarting the ignition will make the onboard computer re-detect the transmission data, and it will be fine after restarting.
