Solution

1. Preparation

Tools Required: Jack and jack stands, drain pan, socket set, torque wrench, transmission fluid.
Raise the vehicle using a jack and secure it with jack stands.
Wear safety gloves and goggles to protect yourself from fluid exposure.

2. Drain Transmission Fluid

Place a drain pan beneath the transmission pan.
Remove the drain plug or loosen the transmission pan bolts to allow the fluid to drain completely.
Clean any residue from the drain area.

3. Inspect and Replace Gasket or Seals

Tools Required: Gasket scraper, seal puller, RTV sealant (if necessary).
Remove the transmission pan by unscrewing the bolts and carefully prying it off.
Inspect the transmission pan gasket for wear or damage and replace it if necessary.
Check the input/output shaft seals; if damaged, remove and replace them using a seal puller.

4. Reinstall Transmission Components

Clean the mating surfaces of the transmission pan and housing to remove old gasket material.
Apply RTV sealant if required and position the new gasket.
Reattach the transmission pan, tightening the bolts to the manufacturer’s specified torque settings.

5. Refill Transmission Fluid

Tools Required: Funnel.
Reinsert the drain plug if applicable.
Using a funnel, pour the appropriate type and amount of new transmission fluid into the transmission.
Start the engine and allow it to reach operating temperature while checking for leaks.
