Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, transmission fluid.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery if working on electrical components.

2. Transmission Fluid Change

Drain Transmission Fluid:
- Locate the transmission drain plug.
- Use a socket set to remove the drain plug and allow fluid to drain into a suitable container.
Replace Filter (if applicable):
- Remove the transmission pan by loosening the bolts with a socket set.
- Replace the filter with a new one, ensuring a proper seal with a new gasket.
Refill Transmission Fluid:
- Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.
- Use a funnel to refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.

3. Inspect and Replace Mounts

Remove Old Mounts:
- Use a socket set to unbolt the engine and transmission mounts.
- Carefully lift the engine/transmission assembly slightly to relieve pressure on the mounts.
Install New Mounts:
- Position the new mounts in place and secure them with bolts, torquing to specifications.
Check Alignment:
- Ensure that the engine and transmission are aligned properly before lowering the assembly back into place.
