Code P281E Cadillac Description

The Transmission Control Module (TCM) receives information from a variety of sensors, switches, and serial data information from other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio, and torque converter clutch operation. A solenoid valve is an electro-mechanically operated valve. The valve is controlled by an electric current through the solenoid. The TCM uses the vehicle speed signal to determine the actual gear position (1st, 2nd, 3rd, 4th. 5th or 6th gear). Then the TCM compares the actual gear with the shift schedule in the TCM memory to detect shift solenoid valves and valve body mechanical problems.
