Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Transmission Fluid Change

Sub-steps:
1. Remove the transmission pan bolts using a socket wrench.
2. Carefully lower the pan and drain the old fluid into a pan.
3. Replace the transmission filter if applicable.
4. Clean the pan and install a new gasket.
5. Refill the transmission with the appropriate type and amount of fluid, as specified in the owner's manual.

3. Inspect and Replace Mounts

Sub-steps:
1. Remove any components obstructing access to the transmission and engine mounts.
2. Use a jack to support the transmission slightly and remove the old mounts.
3. Install new mounts and torque them to the manufacturer's specifications.
4. Reassemble any components that were removed.

4. Drive Shaft Inspection and Replacement (if necessary)

Sub-steps:
1. Remove the drive shaft by loosening the U-joint bolts with a socket set.
2. Inspect U-joints for wear; if excessive play is found, replace the U-joint.
3. Reinstall the drive shaft and torque the bolts to specifications.

5. Differential Fluid Change (if needed)

Sub-steps:
1. Remove the differential cover bolts and drain the old fluid.
2. Clean the mating surfaces and install a new gasket.
3. Refill the differential with the specified fluid.
