Symptoms

- Engine Light ON (or Service Engine Soon Warning Light) - Shift shock

Possible Causes

- Low transmission fluid level - Dirty transmission fluid - Faulty pressure control solenoid valve - Pressure control solenoid valve harness or connectors - Pressure control solenoid valve circuit is open or shorted

When Detected

The P0795 code is detected when the when normal voltage is not applied to solenoid due to open or short or when TCM detects as irregular by comparing target value with monitor value.

Description

The pressure control solenoid valve C is normally low pressure control solenoid. The solenoid is activated to control the apply and release of the 2nd brake and 1st and reverse brake, and torque converter clutch. Lock-up operation, however, is prohibited when A/T fluid temperature is too low. When the accelerator pedal is depressed (less than 1/8) in lockup condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.
