Why does the Land Rover transmission fault disappear after restarting?
1 Answers
It could be due to sporadic or persistent faults in the electronic components of the automatic transmission (such as sensors, solenoid valves, or the transmission control unit), or the transmission fault light may illuminate because of excessively high transmission fluid temperature. Possible causes include overfilling of transmission fluid, internal or external blockage of the transmission cooler (these issues often occur during hot seasons), etc. Here is some relevant information: 1. Transmission: The transmission is a mechanism used to alter the speed and torque from the engine. It can fixedly or variably change the transmission ratio between the output shaft and the input shaft, hence also known as a gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also featuring a power take-off mechanism. 2. Gear Transmission: Most transmission mechanisms use ordinary gear transmission, while some employ planetary gear transmission. Ordinary gear transmission mechanisms typically involve sliding gears and synchronizers, among others. When the relationship between the number of teeth on the driven gear and the driving gear changes, the transmission ratio (i) alters. Under constant engine speed conditions, this affects the output shaft speed, thereby changing the wheel speed.
