Yes, it is necessary to apply sealant to the automatic transmission gasket in the following cases:
* To prevent transmission fluid leaks.
* When the gasket is new and requires additional sealing.
* When installed on uneven surfaces or if there is slight damage to the gasket.
* If the vehicle is operated under high load or temperature conditions.
How to apply sealant:
1. Clean and degrease the surfaces of the gasket and automatic transmission.
2. Apply a thin layer of sealant to both sides of the gasket.
3. Allow the sealant to dry for a few minutes.
4. Install the gasket and attach the automatic transmission to the engine.
5. Tighten the bolts to the specified torque.
Sealant selection:
Use sealant designed for transmissions. These are usually red or blue sealants.
Note: Do not overdo the amount of sealant, as excess can get into the automatic transmission and cause problems.
