Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid dipstick, socket set, torque wrench, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid electrical issues.

2. Check and Replace Transmission Fluid

Remove the transmission fluid dipstick and check the fluid level and color.
If the fluid is low or dark, drain the old transmission fluid using a pan.
Replace the transmission filter if applicable.
Refill the transmission with the manufacturer-recommended fluid type (typically ATF).
Start the engine and allow it to reach operating temperature, then shift through all gears to circulate.

3. Inspect and Replace Transmission Mounts

Lift the vehicle securely using jack stands.
Locate the transmission mounts and visually inspect for cracks or excessive wear.
If damaged, remove the bolts securing the mounts using a socket set.
Replace with new OEM mounts and torque the bolts to the manufacturer's specifications.
Recheck alignment and secure all connections.

4. Check and Replace Drive Shafts or U-Joints

Inspect drive shafts for any visible damage, play, or wear.
If necessary, remove the drive shaft by loosening the bolts and sliding it out of the transmission.
Replace any faulty universal joints or the entire drive shaft if damaged.
Reinstall the drive shaft and torque bolts to the specified values.
