Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.

Tools Required: Transmission fluid pump, fluid catch pan, funnel.
Locate the transmission fluid dipstick or fill plug.
Check the fluid level; if low, fill it to the manufacturer’s specifications with the correct type of transmission fluid.
If the fluid is dark or has a burnt smell, perform a transmission fluid change.

4. Inspect Driveshaft and CV Joints

Tools Required: Socket set, pry bar.
Lift the vehicle and support it securely.
Inspect the driveshaft for any signs of damage or wear.
Check the CV joints for torn boots or excessive play; replace if necessary.
