Consequences of pouring different oils into an automatic transmission (automatic transmission)
Pouring different oils into an automatic transmission can lead to serious problems and damage to the gearbox:
1. Incompatibility of additives:
Different oils may contain incompatible additives that can react and create harmful deposits. This can lead to stuck valves, broken gears, and other mechanical problems.
2. Incorrect viscosity:
Automatic transmission oils have different viscosity values, which affect their fluidity. Filling with oil of the incorrect viscosity may prevent proper lubrication and result in increased component wear.
3. Foaming:
Some oils can interact with others, causing foaming. This can result in low oil pressure and insufficient lubrication, leading to overheating and failure.
4. Corrosion:
Different oils may contain different chemical additives that can be corrosive to the metal components of the automatic transmission. This may cause damage to internal parts such as bearings, gears and housing.
5. Filters are clogged:
Incompatible oils can form deposits that can clog automatic transmission filters. This will restrict oil flow and can lead to starvation and component failure.
The importance of using the correct automatic transmission oil
To ensure proper operation and extend the life of the automatic transmission, it is extremely important to use the type of oil recommended by the manufacturer. Use oil with the correct specifications for fluid type (eg DEXRON or MERCON), viscosity and quality standards (eg API or JASO).
Consequences
If different oils are poured into an automatic transmission, expensive repairs and replacement of the entire unit may be required. The best practice is to follow the vehicle’s owner’s manual and use only automatic transmission oils recommended by the manufacturer.
