Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, torque wrench, and shop towels.
• Safety Warnings: Ensure the vehicle is on a level surface and the engine is cool before starting work.

2. Transmission Fluid Change

1. Drain Old Fluid:

   • Locate the transmission drain plug under the vehicle.
   • Using a socket set, remove the drain plug and allow the old fluid to completely drain into a suitable container.

2. Replace Filter (if applicable):

   • Remove the transmission pan if the filter is accessible.
   • Disconnect the filter from the transmission and install a new filter.
   • Clean the transmission pan and replace the gasket to prevent leaks.

3. Refill Transmission Fluid:

   • Reinstall the drain plug and torque it to the manufacturer’s specifications.
   • Use a funnel to refill the transmission with the correct type and amount of fluid as specified in the owner's manual.

3. Inspect and Adjust Transmission Control Module

1. Check TCM Connections:

   • Remove the protective cover of the TCM.
   • Visually inspect the wiring connectors for corrosion or damage.
   • Reconnect the TCM securely.

2. Reprogram TCM (if required):

   • If error codes indicate TCM issues, follow the manufacturer’s procedure to reprogram or update the TCM software using a compatible scan tool.

4. Inspect and Replace Engine/Transmission Mounts

1. Visual Inspection:

   • Inspect the engine and transmission mounts for cracks, tears, or signs of wear.

2. Replace Damaged Mounts:

   • Using a socket set, remove the bolts securing the damaged mounts.
   • Install new mounts and torque them to specifications.
