Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, jack stands, transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical short circuits.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick or fill port.
Remove the dipstick and wipe it clean. Reinsert it to check the fluid level.
If low, add the manufacturer-recommended transmission fluid until the correct level is reached.
If the fluid is burnt or contaminated, proceed to drain and replace it:
1. Place a drain pan under the transmission.
2. Remove the drain plug and allow the fluid to completely drain.
3. Replace the drain plug and torque it to the manufacturer's specifications.
4. Refill the transmission with the new fluid through the dipstick or fill port.

3. Inspect and Replace Mounts

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the engine and transmission mounts for cracks or excessive wear.
If damaged, replace the mounts:
1. Support the transmission with a jack.
2. Remove the bolts securing the mount to the frame and transmission.
3. Replace with new mounts and torque to specifications.

4. Inspect Driveshaft and CV Joints

With the vehicle raised, inspect the driveshaft and CV joints for any signs of damage or excessive play.
If damaged, replace the affected components:
1. Remove the retaining clips and bolts securing the CV joint or driveshaft.
2. Replace with new parts and ensure proper alignment during installation.
