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. Inspect and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level and condition.
If low, add the recommended transmission fluid as specified in the owner’s manual.
If the fluid is burnt or contaminated, proceed to drain the transmission fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set and carefully lower the pan.
- Allow the old fluid to completely drain.

3. Replace Transmission Filter

Remove the old filter by unscrewing it or unclipping it, depending on the model.
Clean the area around the filter mounting surface.
Install the new transmission filter, ensuring it is seated properly.

4. Reinstall Transmission Pan

Clean the mating surface of the transmission pan.
Apply a new gasket or sealant as required.
Reinstall the transmission pan, tightening the bolts to the manufacturer’s specified torque settings.

5. Refill Transmission Fluid

Using a funnel, add the appropriate type and amount of new transmission fluid through the dipstick tube.
Start the engine and let it idle, shifting through each gear to circulate the fluid.
Check the fluid level again and add more if necessary.
