Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

2. Drain Old Transmission Fluid

Tools Required: Socket set, drain pan, funnel.
Place the drain pan under the transmission pan.
Remove the transmission pan bolts with the socket set.
Carefully lower the pan and allow the old fluid to drain completely.

3. Inspect Transmission Components

Inspect the transmission filter for clogs or damage. Replace if necessary.
Check the condition of the transmission pan gasket; replace if it shows signs of wear.
Look for metal shavings or debris inside the pan, indicating internal wear.

4. Install New Transmission Filter and Gasket

Clean the transmission pan thoroughly.
Install the new filter, ensuring it is seated correctly.
Apply a new gasket to the transmission pan and torque bolts to manufacturer specifications (typically 8-10 ft-lbs).

5. Refill with New Transmission Fluid

Parts Required: New transmission fluid (check owner’s manual for specifications).
Using a funnel, pour the new transmission fluid into the dipstick tube.
Start with the manufacturer-recommended amount and check the level with the dipstick.

6. Final Checks

Reconnect the battery.
Start the engine and let it idle while shifting through all gears to circulate the new fluid.
Check for leaks around the pan and ensure fluid level is correct.
