Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Change Transmission Fluid

Tools Required: Socket set, wrench, fluid pump, drain pan.
Remove the transmission drain plug using a socket wrench and allow the old fluid to drain completely into the drain pan.
Replace the drain plug and torque it to the manufacturer’s specifications.
Using a fluid pump, add new transmission fluid through the dipstick tube until the correct level is reached (refer to owner's manual for specific fluid type and capacity).

3. Replace Transmission Filter

Tools Required: Socket set, gasket scraper, torque wrench.
Remove the transmission pan by unscrewing the bolts using a socket set and carefully lower it to avoid spilling fluid.
Remove the old transmission filter and discard it.
Install the new transmission filter, ensuring it is seated properly.
Clean the mating surfaces of the transmission pan and the transmission body.
Install a new gasket on the transmission pan and reattach it, torquing the bolts to the specified value.

4. Check and Adjust Transmission Fluid Level

Start the engine and let it idle for a few minutes.
Cycle through the gears to allow the fluid to circulate.
With the engine running, check the transmission fluid level using the dipstick and add fluid as necessary to reach the correct level.
