Consequences of an increased oil level in an automatic transmission:
* Increased wear of automatic transmission components, such as clutches, transmission shaft and bearings, due to excess oil pressure.
*Transmission slipping due to the oil’s inability to properly lubricate and cool components.
* Overheating of the automatic transmission due to increased friction and resistance to oil flow.
* Damage to automatic transmission seals and gaskets due to excess oil pressure.
*Oil oxidation and sludge formation due to higher temperature.
* Reduced automatic transmission efficiency and gear shifting at inappropriate times.
* Oil foaming resulting in insufficient lubrication and cooling of components.
* Malfunctions of electronic sensors and solenoids in the automatic transmission due to oil ingress.
* Damage to other transmission components such as differential or drive shafts due to increased oil pressure.
In severe cases, elevated automatic transmission oil levels can lead to catastrophic transmission failure, requiring expensive repairs or replacement.
