Solution

1. Determine Service Interval

Refer to the owner's manual to find the recommended service interval for the transmission, usually specified in miles or kilometers.
Typical intervals for conventional fluid changes are every 30,000 to 60,000 miles, while some vehicles with synthetic fluid may extend this to 100,000 miles.

2. Inspect Transmission Fluid

Tools Required: Dipstick or fluid level gauge, clean cloth.
Remove the dipstick or access the fluid level port.
Wipe the dipstick clean and reinsert it, then remove it again to check the fluid level.
Inspect the fluid color and consistency; it should be a clear reddish hue, not dark or burnt.

3. Change Transmission Fluid and Filter (if applicable)

Tools Required: Socket set, wrench set, transmission fluid pump, new transmission fluid, new filter (if applicable).
Raise the vehicle securely using jack stands.
Drain the old transmission fluid by removing the drain plug or pan, allowing it to fully drain into a suitable container.
Remove and replace the transmission filter, if equipped, following the manufacturer’s specifications.
Reinstall the drain plug or pan with a new gasket if necessary, and tighten to specified torque.
Refill the transmission with the appropriate type and amount of new fluid as specified in the owner's manual using the fluid pump.

4. Check for Leaks

Start the vehicle and allow it to reach operating temperature.
With the engine running, check for any leaks around the drain plug, filter, and any hoses.
If leaks are detected, tighten any fittings or replace gaskets as necessary.
