Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Fluid Change

Tools Needed: Transmission fluid pump, drain pan, funnel, socket set.
Remove the drain plug from the transmission pan using the socket set.
Allow the old fluid to drain completely into the drain pan.
Replace the drain plug and torque it to the manufacturer’s specifications.

3. Inspect and Replace Seals

Tools Needed: Seal puller, socket set, torque wrench.
Remove the transmission pan to access the internal components.
Inspect the transmission pan gasket for wear and replace it if necessary.
Check the input and output shaft seals; if they appear worn, replace them using a seal puller.

4. Check and Replace Filter

Tools Needed: Socket set, new transmission filter, gasket.
Remove the old transmission filter and replace it with a new one.
Ensure that the filter is seated properly and secure it in place.

5. Refill Transmission Fluid

Use a transmission fluid pump to refill with the appropriate type of new transmission fluid.
Start the engine and allow it to idle for a few minutes.
Check the fluid level again using the dipstick and add more fluid if necessary.
