Causes of oil leakage on the automatic transmission pan gasket:
* Old or damaged gasket: Over time, rubber gaskets can wear out and crack, causing leaks.
* Overtightened or undertightened pan bolts: Improperly tightened pan bolts can create gaps through which oil can leak.
* Pan deformation: The automatic transmission pan can become deformed due to impacts or improper installation, which can also lead to leaks.
* Gasket Shrinkage: Once installed, a new gasket may shrink slightly, causing minor leaks during the first few days.
* High pressure in the automatic transmission: If the pressure in the automatic transmission is too high, it can put excessive stress on the gasket, causing a leak.
* Defective Gasket: In rare cases, the gasket may have a defect that causes a leak.
Consequences of an oil leak:
*Low automatic transmission oil level: This can lead to insufficient lubrication, which will lead to damage to automatic transmission components.
* Gear slippage: Insufficient oil pressure can cause gear slippage, making the vehicle difficult to control.
* Automatic transmission overheating: An oil leak can cause the automatic transmission to overheat, which can shorten its service life.
* Automatic transmission failure: in severe cases, an oil leak can lead to automatic transmission failure, which will require expensive repairs or replacement.
Solution:
* Replace the pan gasket with a new one.
* Check the pan bolts and, if necessary, tighten them to the appropriate torque.
* Inspect the pallet for deformation and, if necessary, repair or replace it.
* Check the pressure in the automatic transmission and eliminate any problems that may increase it.
* Check the gasket for defects and replace it if necessary.
Prevention Tips:
* Regularly check the oil level in the automatic transmission and the condition of the pan gasket.
*Follow the manufacturer’s instructions for tightening the pan bolts.
* Bring your car to a service center for scheduled automatic transmission maintenance.
* Avoid harsh driving which may damage the pan.
