What Signs Can Help Prevent the Failure of Automatic Gearbox?

The gearbox transmits engine power (torque) to the rear wheels through a series of graduated gears, doing so smoothly and with perfect synchronization. However, every mechanical component may fail if it occurs problems, so does the automatic gearbox, the signs appeared on gearbox shift forks, shift block, shift fingers, or balanced connectors cannot be ignored. The failure of car gearbox may affect your daily driving experience. Therefore, you have to take note of the signs which may give you some help to prevent it from failure.

Leak

The gearbox will leak mostly from external sources since its design is a closed system. For instance, if the input or output gearbox shaft seals have worn, there will be a leak at the end of the gearbox tail shaft (near the front drive-line U-joint) or at the bottom of the bell housing. All leaks should be tracked down and repaired.

Dirty filter

Automatic gearboxes have a filter screen device located in the main pan. The filter traps all metal shavings and foreign debris and keeps them from entering the delicate channels and passages in the gearbox valve body. Dirty or contaminated gearbox fluid will not have a clean red color, but look muddy or yellow.

Inadequate transmission fluid

This may be the most normal reason for automatic gearbox or gearbox differential housing slippage, overheating or non-operation can be. The transmission fluid works as the liquid power source that switches and drives the gears under pressure while maintaining the interior parts lubricated and cool. If it gets too low, the remaining fluid cannot be picked up by the pump and circulated through the system. Less fluid translates to reduced temperature control, which leads to overheating and transmission fluid that will lose its viscosity.

Some others signs such as the gearbox shift forks linkage and vacuum control devices and so on. They are all very essential for you to look out for when the automatic gearbox begins to fail.
