Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery before starting work to prevent electrical shorts.
Allow the vehicle to cool down if it has been running.

1. Locate the transmission dipstick or fill port.
2. Remove the dipstick or fill plug and check the fluid level.
3. If low, add the recommended transmission fluid (check the owner’s manual for specifications).
4. If fluid is dark or burnt, drain the transmission fluid using a catch pan.
5. Replace with new transmission fluid through the fill port using a funnel.

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, new transmission filter, gasket (if applicable).
Sub-steps:
1. Remove the transmission pan by unbolting it (ensure the catch pan is below to collect fluid).
2. Remove and discard the old transmission filter.
