What are the causes of Cadillac XT5 transmission failure?

[DeHenry]

Cadillac XT5 transmission failure causes: 1. Fault in the power electronic control system, possibly due to a faulty sensor connection circuit in the transmission; 2. Lack of automatic transmission fluid; 3. Automatic transmission overheating or failure to increase speed due to a slipping one-way clutch, etc. Functions of the transmission: 1. Change the transmission ratio: Meet the traction needs under different driving conditions, allowing the engine to operate under optimal conditions and meet possible speed requirements. 2. Enable reverse driving: To meet the need for the car to move backward. The engine crankshaft generally only rotates in one direction, but sometimes the car needs to move backward, hence the reverse gear in the transmission is often used to achieve this. 3. Interrupt power transmission: When starting the engine, idling, shifting gears, or needing to stop for power output, the power transmission to the drive wheels is interrupted. 4. Enable neutral gear: When the clutch is engaged, the transmission can output no power. For example, it allows the driver to release the clutch pedal and leave the driver's seat without turning off the engine.
