4. Install new mounts, ensuring they are correctly aligned, and torque bolts to manufacturer specifications.

3. Inspect and Change Transmission Fluid

Sub-steps:
1. Remove the transmission drain plug using a wrench and allow old fluid to drain into a collection pan.
2. Replace the transmission filter if applicable; consult the manual for the filter location and replacement procedure.
3. Install the drain plug and torque it to the specified value.
4. Refill the transmission with the correct type and amount of fluid as per manufacturer specifications.

4. Inspect Driveshaft and CV Joints

Sub-steps:
