Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick.
2. Use a fluid extractor to drain the old transmission fluid into a suitable container.
3. Replace the transmission filter (if applicable) by removing the pan bolts and taking out the filter.
4. Install a new filter and clean the pan before reinstallation.
5. Refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Locate the transmission mounts and inspect them for cracks or signs of wear.
3. If damaged, remove the bolts securing the mounts using a socket set.
4. Replace with new mounts, ensuring proper alignment before tightening to manufacturer torque specifications.

4. Test and Replace Throttle Position Sensor (if faulty)

Sub-steps:
1. Disconnect the electrical connector from the TPS.
2. Use a multimeter to test the resistance across the TPS terminals as per manufacturer specifications.
3. If out of range, remove the TPS from the throttle body and replace it with a new one.
4. Reconnect the electrical connector and clear any fault codes.
