Cleaning of automatic gearbox

What happens when the automatic transmission fluid in the automatic transmission is dirty? First of all, the carbon deposition of sludge in dirty oil will form abrasive wear, which will aggravate the wear of friction plates and parts and reduce the life of parts. Second, the sludge carbon deposit in the dirty oil will make the oil in all valve body oil pipes flow poorly, which will affect the power transmission, thus slowing down or stalling the automatic gearbox, and in serious cases, it will make one gear have no oil pressure and cause combustion. Thirdly, the dirty oil will cause premature aging of the sealing aprons between cylinders, which will affect the unloading oil pressure of each cylinder, and will also cause failures such as slow growth and stall, and even make the friction plates slip and burn.

If your gearbox is continuously variable transmission (CVT) or dual clutch (DSG, power shift, etc. ), it is not necessary, which is determined by the structure of its gearbox itself; If you are an ordinary automatic gearbox, it is necessary. A lubricating oil called ATF is added to the automatic gearbox, which not only plays the role of lubrication and cooling, but also transfers power between the engine and gearbox through the flow of oil. The working temperature of ATF oil is generally around 140℃. Due to the high oil temperature, carbon deposition and sludge are more likely to occur, which makes the oil in various valve body oil pipes flow poorly, slows down or stalls the gearbox and shortens the service life of the gearbox. Therefore, it is very necessary to change the lubricating oil of automatic transmission regularly.

When changing transmission oil, it is suggested that automatic transmission cleaner and automatic transmission protector can be used. Automatic gearbox cleaning agent can remove oil sludge and carbon deposit in gearbox system, clean parts and pipelines, and reduce secondary pollution to new oil. Adding automatic gearbox protective agent after changing gearbox oil can enhance the oxidation resistance, emulsification resistance, wear resistance and high lubrication performance of gearbox oil, make automatic gear shifting smooth, avoid overheating and burning of clutch plates, provide lubrication protection, delay the aging and failure of oil and prolong the service life of gearbox.
