Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid pressure gauge, fluid catch pan.
Ensure the vehicle is on a flat surface and the engine is off before starting.
Disconnect the battery to avoid electrical shorts.

2. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean and reinsert it fully.
3. Remove it again and check fluid level; add fluid if low.
4. Inspect fluid condition; replace fluid if it’s dark or smells burnt.

3. Replace Transmission Filter

Sub-steps:
1. Raise the vehicle using jack stands and secure it.
2. Remove the transmission pan bolts and carefully lower the pan.
3. Clean the pan and magnet, removing any debris.
4. Replace the old filter with a new one, ensuring proper alignment.
5. Reinstall the transmission pan with a new gasket, torque bolts to specifications.

4. Fluid Change

Sub-steps:
1. With the vehicle still elevated, place a catch pan under the transmission.
2. Remove the transmission drain plug and allow old fluid to drain completely.
3. Replace the drain plug and refill with the recommended transmission fluid type.
4. Start the engine and run through the gears to circulate the fluid.
