Drain the old transmission fluid into a catch pan.
Replace the fluid filter if it is clogged or damaged.
Refill with the manufacturer-recommended transmission fluid (typically Toyota WS fluid).
Torque the pan bolts to specifications (usually around 7.5 ft-lbs).

3. Inspect and Replace Transmission Mounts

Tools Required: Socket set, jack and jack stands.
Raise the vehicle securely using jack stands.
Locate the transmission mounts and inspect for cracks or excessive wear.
Remove the bolts securing the old mounts to the transmission and the frame.
Install new mounts, ensuring they are properly aligned and torque to specified values.

4. Inspect Driveshaft and CV Joints

Tools Required: Socket set, pry bar.
Visually inspect the driveshaft for any signs of damage or play.
Check CV joints for torn boots or excessive movement.
Replace any damaged driveshaft components or CV joints as needed, ensuring proper alignment during installation.
