Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
Remove the transmission dipstick and wipe it clean.
Insert the dipstick back, remove it again, and check the fluid level.
If low, add the recommended transmission fluid (consult owner's manual for specifications).
If the fluid appears dirty or burnt, proceed to replace the fluid.

3. Drain Old Transmission Fluid

Locate the transmission drain plug and place a drain pan underneath.
Remove the drain plug using a socket wrench, allowing the old fluid to drain completely.
Reinstall the drain plug and torque to manufacturer specifications.

4. Fill New Transmission Fluid

Using a funnel, add new transmission fluid through the dipstick tube.
Start the engine and let it idle for a few minutes.
Shift through all gears (P, R, N, D) to circulate the fluid.
Check the fluid level again and add more fluid as necessary.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Take the vehicle for a test drive to ensure proper shifting and that the warning light is off.
