Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical issues during repair.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the appropriate type of transmission fluid (consult the owner's manual for specifications).
If the fluid is dark or smells burnt, drain the old fluid using a drain pan.
Replace with new transmission fluid, ensuring it meets manufacturer specifications.

3. Inspect and Replace Transmission Filter

Remove the transmission pan using a socket set; clean the pan thoroughly.
Replace the transmission filter according to the manufacturer’s specifications.
Reinstall the pan using a new gasket and torque it to the manufacturer's specifications.

4. Inspect and Repair Mechanical Components

If mechanical issues are detected, such as worn clutches or bands, disassemble the transmission as needed.
Replace any damaged components with OEM parts.
Reassemble the transmission, ensuring all seals and gaskets are replaced.

5. Reconnect and Test

Reconnect the battery.
Start the engine and allow it to warm up to operational temperature.
Test drive the vehicle to ensure smooth shifting and no jerking.
