Car gearboxes, which are important components of vehicle formation, continue to be marketed as competition between companies becomes more intense. And when many of the gearboxes are over 100,000 kilometres away, there are certain problems, including some high-end brands, and we are here today to teach you how to run a failure check on automatic gearboxes。
Common automatic gearbox failure:
It's a serious setback
First of all, it should be emphasized that when the automatic block vehicle does not reach a certain speed and the oil door is put to the bottom, and when the lower gear is at a high rate, the frustration that the block needs to be changed is not the failure of the gearbox. However, in the case of slow and medium-speed vehicles, when there is a clear frustration or a volatile rotation schedule, or when the vehicle is flying at high speed, it is generally certain that the speedbox has malfunctioned。
The gearbox jumps or can't rise or fall. Block
When vehicles enter a particular block, the vehicle moves over one block to the next when there is a strong frustration, and the jump is easily detected when the vehicle moves at high speed. Most of the brakes occurred between blocks 3-5, indicating that the vehicle had severe mechanical malfunctions that required immediate repair, most likely as a result of poor exposure to the electromagnetic valves。
Fuel leak in the gearbox
This is the most common failure of automatic transformer containers, which differ in nature from oil seepages, which are caused only by the ageing of the oil seals and do not worry too much about small areas. Oil spills are defined as seepage fluids that can form droplets and must be repaired。
Whether or not the transformer tank is leaking can be easily identified: it is generally located directly below the vehicle block, and a basic determination can be made by moving a distance after the start-up of the vehicle to see if there are oil stains on the ground。
The oil is milky
When white solids are found on the scale from which the gearbox is extracted, this means that the gearbox is mixed with other liquids. When vehicles enter the water, the flow of gas from the gearbox into the water leads to this, or the failure of the speedbox heater leads to the flow of other liquids. The situation was detected by checking the gearbox in time to avoid damage to it. The blacking of the transformer tank oil is, of course, a “warning”: you need to replace the transformer tank oil or internal parts are already in trouble。
Summary
Most of the failure of the automatic transformer was caused by the deterioration of the tank's oil, which led to increased wear and tear of the various parts of the transformer, resulting in slippages, noises and shocks, so that the good oil largely ensured the safety of the vehicle。
Of course, there are also a number of problems caused by the lack of motor vehicle owners in various aspects of gearbox maintenance, and here we suggest that, as soon as problems with gearbox maintenance are identified, they must be sent to the regular gearbox maintenance centre for inspection and repair in a timely manner。
