Solution

1. Preparation

Tools Required: Socket set, torque wrench, transmission fluid pump, screwdriver, drain pan.
Ensure the vehicle is on a level surface and securely elevated using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan and allow the fluid to drain completely into the pan.

3. Inspect and Replace Gasket/Seal

Tools Required: Gasket scraper, cleaner.
Remove the old gasket material from the transmission pan and the mating surface of the transmission.
Inspect the condition of the pan and replace if damaged.
If leaks are found at the seals, replace the input and output shaft seals. Use a seal puller for easier removal if necessary.

4. Reinstall Transmission Pan

Place a new gasket on the transmission pan.
Align the pan and hand-tighten the bolts before using the torque wrench to tighten to manufacturer specifications (typically around 10-15 ft-lbs).
Ensure no cross-threading occurs during installation.

5. Refill Transmission Fluid

Using a transmission fluid pump, refill the transmission with the correct type of fluid specified in the owner's manual.
Start the engine and allow it to idle while moving through all gears to circulate the fluid.
Check the fluid level again and add as necessary.

6. Final Check

Reconnect the negative battery terminal.
Test drive the vehicle to confirm the issue is resolved.
