Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, multimeter, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during the repair.

2. Fluid Inspection and Replacement

Sub-steps:
1. Remove the transmission dipstick and check the fluid level.
2. If low, add the appropriate type of transmission fluid as specified in the owner's manual.
3. If fluid is dirty or burnt, proceed to drain the transmission fluid.
  - Place a fluid catch pan under the transmission drain plug.
  - Remove the drain plug with a socket set and allow the fluid to drain completely.
4. Replace the drain plug and torque it to manufacturer specifications.
5. Refill the transmission with new fluid through the dipstick tube, ensuring the correct amount is added.

3. Transmission Control Module (TCM) Check and Reprogramming

Sub-steps:
1. Reconnect the battery and access the TCM.
2. Use the OBD-II scanner to check for any firmware updates or necessary reprogramming.
3. Follow the scanner prompts to perform the TCM reprogramming if needed.

4. Mounts Inspection and Replacement

Sub-steps:
1. Visually inspect the engine and transmission mounts for cracks or separation.
2. If damaged, remove the old mounts using a socket set.
3. Install new mounts and torque to specifications provided by the manufacturer.
