Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, torque wrench.
Ensure the vehicle is on a flat surface and securely raised using jack stands.
Disconnect the battery to avoid any electrical short circuits.

2. Transmission Fluid Change

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the old fluid.
3. Inspect the old fluid for metal shavings or burnt smell.
4. Clean the transmission pan and replace the filter if applicable.
5. Reinstall the transmission pan and torque the bolts to manufacturer's specifications.
6. Fill the transmission with new fluid using a funnel, ensuring the correct type and quantity as specified in the owner’s manual.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Locate the transmission mounts and inspect for cracks or wear.
2. If damaged, remove the bolts securing the mounts using a socket set and lift the transmission slightly to relieve pressure.
3. Replace the old mounts with new ones, ensuring proper alignment.
4. Torque the bolts to the manufacturer’s specifications.

4. Test Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids according to the service manual.
2. Disconnect the electrical connectors and test the solenoids with a multimeter for continuity.
3. If any solenoids are faulty, replace them with new parts as per the manufacturer’s guidelines.
