Additive for the automatic transmission is designed to preserve and restore parts of the automatic transmission.
What is cause of gear shifting delays in automatic transmission?
Modern automatic transmission, regardless of the manufacturer, is a complex device that combines the operation of several different systems. Even not considering the torque converter there is a mechanical system of several planetary gears, clutch packs and shafts. It is managed by hydraulic system that provides the application of forces to compress clutch packs. And all this is controlled by electronics with sensors and processors.
However, the most common cause of incorrect operation of the automatic transmission is wear of the oil pump, which causes a drop in pressure in the hydraulic unit. At the moment when the electronics indicate a gear change, certain valves are opened and closed in the hydro-block, allowing the oil to enter the channels and transmit pressure to the corresponding clutch package. If pressure is low, the compression is not fast enough, there is a delay of switching, the frictions scroll and for some time the box does not transmit the torque properly.
It feels like a jerk at gears shift. Sometimes it is said that "the box is kicking" or "there are bumps when shifting". This jerk occurs at the moment when the clutch package is finally locked and begins to transmit torque, but the speed of rotation of the shaft has already fallen.
Treatment of automatic transmission with tribotechnical compound can eliminate these problems.
Problems with the automatic transmission can occur for a number of reasons. One of them is the wear of gear teeth. When their interaction is disrupted, coming in and out of engagement get micro-shocks, which cause unwanted vibrations and noise.
Does transmission oil additive resolve gear shifting delays for sure?
Aside the common problem described above there may be other reasons of jerks and kicks of automatic transmission.
First of all it is quality and quantity of automatic transmission fluid in the gearbox. In time oil is collecting dirt and metallic particles and may loose its viscosity level. There may be some oil leaks decreasing its level. Oil filter may be clogged lowering the pressure. Or the transmission fluid may be overheated due traffic jams and loose its ability to transmit torque. There are no auto gearbox oil additives which could help with this kind of problems. You should change oil and filter.
It is highly recommended to use Atomium AGSB compound immediately after oil change. It will restore worn out gears, oil pump, bearings and protect your transmission for a long time.
Other reasons of troubled gear shift is mechanical breakage of some details. There may be problems with solenoid valves – distortion of their channels, deposits etc. Clutch packs may be heavily worn out or burn out and require more pressure that pump is able to provide. The whole hydro block may be distorted because of gearbox overheat. Even some external parts may affect smooth gear shifting. It may be for example worn out engine and gearbox mounts – the gearbox is tilted at switching from parking mode to drive or reverse ones and it results in a jerk.
Again – no transmission fluid additives are able to help here. You should check up and change parts. Add Atomium AGSB after the repair to avoid the same problems in the future.
Sometimes the reason of jerks may be caused by electronic controller. It may be broken itself, or to get wrong information from sensors. It will lead to mistakes in gearbox operating. Here you need a through checking of the car on a service station.
