Solution

1. Fluid Change

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts and carefully lower the pan to drain fluid.
4. Replace the transmission filter if applicable.
5. Clean the pan and magnet to remove metal shavings.
6. Reinstall the pan with a new gasket, torque bolts to manufacturer's specifications.
7. Fill the transmission with fresh fluid through the dipstick tube (ensure the correct fluid type is used).

2. Inspect and Replace Transmission Mounts

Sub-steps:
1. Support the transmission with a jack.
2. Remove the bolts securing the old transmission mounts.
3. Install new transmission mounts, ensuring they are properly aligned.
4. Torque the bolts to manufacturer specifications.

3. Addressing Throttle Position Sensor (if necessary)

Sub-steps:
1. Disconnect the battery.
2. Locate the throttle position sensor (TPS) on the throttle body.
