Solution

1. Preparation

Tools Required: OBD-II scanner, fluid pump, socket set, multimeter, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during repairs.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back and pull it out to check the fluid level.
- If low, use a fluid pump to add the appropriate transmission fluid as specified in the owner's manual.
If the fluid appears dark or burnt, proceed to drain and replace:
- Locate the transmission drain plug and remove it using a socket set.
- Allow the old fluid to drain completely into a suitable container.
- Replace the drain plug and torque to manufacturer specifications.
- Refill with new transmission fluid via the dipstick tube, using a funnel.

3. Inspect and Replace Transmission Filter (if applicable)

Remove the transmission pan by unscrewing the bolts with a socket set.
Carefully lower the pan and remove the old filter.
Install the new filter by aligning it with the mounting points.
Clean the transmission pan and reinstall it using a new gasket, torquing the bolts to manufacturer specifications.

4. Test Transmission Components

Reconnect the battery and use a multimeter to test the solenoids and sensors for continuity.
Replace any faulty components as identified.
Clear any diagnostic trouble codes using the OBD-II scanner.
