Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Transmission funnel
- Fluid catch pan

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and inspect the fluid condition. It should be a bright red color and not smell burnt.
If the fluid is low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is dark or has particles, consider a fluid change.
- Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Place the fluid catch pan under the transmission pan.
  3. Remove the transmission pan bolts and gently lower the pan.
  4. Replace the transmission filter if applicable.
  5. Clean the pan and magnet, then reattach it with a new gasket.
  6. Refill the transmission with new fluid through the dipstick tube using a funnel.

3. Inspect Transmission Components

Inspect the transmission mounts for any signs of wear or damage.
- Sub-steps:
  1. Visually check the mounts for cracks or excessive wear.
  2. Replace any damaged mounts as needed.

4. Reset Transmission Control Module

If no mechanical issues are found, reset the Transmission Control Module (TCM).
- Sub-steps:
  1. Disconnect the battery for at least 10 minutes.
  2. Reconnect the battery and start the vehicle.
  3. Allow the vehicle to idle and then take it for a test drive to help the TCM relearn the shifting patterns.
