2. Transmission Fluid Inspection

Check the transmission fluid level using the dipstick.
- If low, add the manufacturer-recommended transmission fluid until the correct level is reached.
Inspect the fluid condition.
- If dark or smells burnt, proceed to replace the transmission fluid.

3. Replace Transmission Fluid (if necessary)

Tools Required: Transmission fluid pump, fluid catch pan.
Drain the old transmission fluid using the drain plug at the bottom of the transmission.
Replace the transmission filter (if applicable) as per the manufacturer's specifications.
Refill with new transmission fluid using the pump through the dipstick tube.
- Refer to the owner’s manual for the correct fluid type and capacity.
Torque the drain plug to the manufacturer's specifications.
