Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, transmission fluid, funnel, torque wrench, and a clean cloth.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean and reinsert it to check the fluid level.
3. If low, add the recommended type of transmission fluid through the dipstick tube using a funnel.
4. If the fluid is dark or has a burnt smell, proceed to drain and replace the fluid.
5. To drain, locate the transmission pan and remove the drain plug (if equipped) or the pan itself.
6. Allow the old fluid to fully drain, then replace the drain plug and torque to manufacturer specifications.
7. Refill the transmission with new fluid using the dipstick tube.

3. Replace Transmission Filter

Sub-steps:
1. If the vehicle has a serviceable transmission filter, remove the transmission pan (if not previously done).
2. Disconnect the filter from the transmission and replace it with a new one.
3. Clean the pan gasket surface and install a new gasket if necessary.
4. Reinstall the transmission pan and torque to manufacturer specifications.

4. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage and inspect for any signs of wear or misalignment.
2. Adjust the linkage as necessary to ensure proper engagement with the transmission.
3. Test the shifting action to confirm smooth operation.
