What Causes a Car to Display Transmission Failure?

[Penny]

There are several reasons why a car may display a transmission failure: 1. There is a fault in the power electronic control system, possibly due to a faulty connection in one of the transmission sensors. A car repair shop can diagnose this through a computer scan and identify the specific issue based on the fault code. 2. Lack of automatic transmission fluid, overheating of the automatic transmission, or failure to increase speed due to a slipping one-way clutch. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts, also known as the gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some cars also featuring a power output mechanism. Most transmission mechanisms use standard gear transmission, while some employ planetary gear transmission.
