Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
- Locate the transmission dipstick or fill plug.
- Remove the dipstick and check the fluid level. If low, add the correct type of transmission fluid as per the owner's manual.
- If the fluid is dark or has a burnt smell, drain the transmission fluid using a wrench to remove the pan bolts.
- Replace the transmission filter if applicable.
- Refill the transmission with new fluid, ensuring it’s at the correct level and type.
Tools Required: Socket set, fluid pump, funnel.

3. Inspect and Replace Transmission Mounts

Sub-steps:
- Locate the transmission mounts under the vehicle.
- Use a jack to slightly lift the transmission to relieve pressure on the mounts.
- Remove the bolts securing the old transmission mounts using a socket wrench.
- Install new mounts in the same position, ensuring they are properly aligned and secured.
- Lower the transmission back into place and tighten the bolts to the manufacturer's torque specifications.
Tools Required: Jack, socket wrench.

4. Check and Replace Torque Converter

Sub-steps:
- Remove the transmission pan and drain any remaining fluid.
- Disconnect the torque converter from the transmission by removing the bolts securing it.
- Install the new torque converter by aligning it with the input shaft and securing it with bolts.
- Reassemble the transmission pan and refill with fresh transmission fluid.
Tools Required: Socket set, torque wrench.
