Is It Necessary to Replace a Rusty Transmission?

[DeHector]

It is necessary to replace a rusty transmission because rust can cause gear shifting issues, such as difficulty engaging gears or gear slippage, which compromises driving safety. Below are details about transmissions: 1. Function: A transmission is a gearbox that changes the transmission ratio and direction of motion. Located between the clutch and the central drive, its main purposes are: changing the vehicle's driving force and speed (gear shifting) without altering the engine's speed and torque; enabling the vehicle to move backward (reverse); and allowing the engine to idle without stalling (neutral). 2. Classification: Based on the transmission type, gear transmissions can be divided into three categories: two-shaft, three-shaft, and compound. The two-shaft type has two main shafts (excluding the reverse shaft) and only requires one pair of gears for speed reduction. The three-shaft type has three main shafts (input shaft, intermediate shaft, and output shaft) and requires two pairs of gears for speed reduction. The compound type consists of two transmissions connected in series or parallel to achieve more gear positions with fewer gears.
