Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the battery before starting work on electrical components.

2. Transmission Fluid Inspection and Replacement

Tools Required: Socket set, fluid pump, transmission filter kit, torque wrench.
Check the transmission fluid level using the dipstick. If low, add the appropriate ATF (Automatic Transmission Fluid) as specified in the owner’s manual.
If fluid is discolored or has a burnt smell, drain the transmission fluid completely.
Remove the transmission pan, replace the filter, and clean the pan’s magnet.
Reinstall the pan and torque to manufacturer specifications.
Refill with new ATF through the dipstick tube.

3. Engine Mount Replacement

Tools Required: Socket set, jack and jack stands, pry bar.
Lift the vehicle using a jack and secure it with jack stands.
Locate the engine mounts and inspect them for cracks or wear.
Remove the bolts securing the damaged engine mount using a socket set.
Replace with a new engine mount, ensuring proper alignment.
Torque bolts to the manufacturer’s specifications.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar.
Raise the vehicle and inspect the driveshaft for signs of damage or excessive play.
Check the CV joints for torn boots or grease leakage.
If damaged, replace the driveshaft or CV joints as necessary.
