Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, floor jack, jack stands, transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off. Engage the parking brake and wear safety gloves.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a floor jack and secure it with jack stands.
2. Locate the transmission fluid dipstick or fill plug.
3. Remove the dipstick or fill plug and check the fluid level. If low, add the manufacturer-recommended transmission fluid.
4. If the fluid is discolored or has a burnt smell, drain the old fluid using a catch pan, then replace it with new fluid.
5. Reinstall the dipstick or fill plug securely.

3. Inspect Transmission Mounts

Sub-steps:
1. Visually inspect the engine and transmission mounts for cracks or excessive wear.
2. If damaged, remove the fasteners holding the mounts using a socket set.
3. Replace the damaged mounts with new ones, ensuring they are torqued to the manufacturer’s specifications.

4. Reset Transmission Adaptations

Sub-steps:
1. With the OBD-II scanner, navigate to the transmission control module.
2. Perform a reset of the transmission adaptations to recalibrate the shifting behavior.
3. Follow any specific prompts on the scanner to complete the process.
