Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid dipstick, funnel, rags, jack and jack stands.
Sub-steps:
- Park the vehicle on a level surface and engage the parking brake.
- Disconnect the battery for safety.
- Raise the vehicle using a jack and secure it with jack stands.

2. Transmission Fluid Inspection

Sub-steps:
- Remove the transmission dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the fluid level.
- If low, add the appropriate type of transmission fluid per the owner's manual.
- Check the fluid condition; if it’s dark or has a burnt smell, it needs to be replaced.

3. Fluid Replacement

Sub-steps:
- Locate the transmission pan and drain plug (if applicable).
- Place a drain pan under the transmission and remove the drain plug to drain the old fluid.
- Remove the transmission pan and replace the filter if necessary.
- Reinstall the transmission pan with a new gasket and torque the bolts to manufacturer specifications.
- Refill the transmission with the correct type and amount of fluid.

4. Inspect and Adjust Transmission Linkage

Sub-steps:
- Locate the transmission linkage and inspect for wear or damage.
- Adjust the linkage as needed to ensure proper engagement.
- Lubricate moving parts if necessary.

5. Test Drive and Monitor

Sub-steps:
- Reconnect the battery.
- Start the engine and allow it to warm up.
- Test drive the vehicle, observing for any slipping or abnormal behavior.
- Check for leaks under the vehicle post-test drive.
