Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check the fluid level.
2. If the fluid is low, add the appropriate type of transmission fluid (Toyota ATF WS).
3. If the fluid is discolored or has a burnt smell, drain the transmission fluid.
4. Use a socket set to remove the transmission pan, if necessary.
5. Replace the filter inside the transmission, if applicable, and reassemble the pan with a new gasket.
6. Refill the transmission with the correct amount of fluid.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Use a jack to support the transmission gently.
2. Remove the bolts securing the transmission mounts using a socket set.
3. Inspect the mounts for cracks or deterioration.
4. If damaged, install new mounts by positioning them correctly and tightening the bolts to manufacturer specifications (usually around 30-40 ft-lbs).
5. Lower the transmission jack once the mounts are secured.

4. Inspect Drivetrain Components

Sub-steps:
1. Check the driveshaft for any signs of wear or damage, such as cracks or excessive play.
2. Examine the CV joints for torn boots or lubricant leakage.
3. If any components are damaged, replace them with OEM parts.
4. Reassemble any disassembled components and ensure they are securely fastened.
