What Causes Transmission Function Limitation?

[HenryFitz]

Transmission function limitation is caused by a malfunction in the transmission hydraulic control unit, which requires disassembly of the unit, also known as the transmission computer and valve body. Below is an introduction to the three main functions of a transmission: 1. Changing the gear ratio: This meets the traction needs under different driving conditions, allowing the engine to operate as efficiently as possible under favorable conditions and meeting potential speed requirements. It enables significant changes in vehicle speed and torque at the drive wheels. 2. Enabling reverse driving: This function satisfies the need for the vehicle to move backward. Since the engine crankshaft generally only rotates in one direction, the reverse gear in the transmission is used to allow the vehicle to move in reverse. 3. Interrupting power transmission: This function is used when starting the engine, during idle operation, when shifting gears, or when stopping the vehicle to output power, cutting off power transmission to the drive wheels.
