Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid pump, transmission fluid.
Safety Warnings: Disconnect the battery before starting any electrical work on the vehicle.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Locate the transmission fluid dipstick and remove it.
3. If fluid is low or dirty, drain the old fluid using a transmission fluid pump.
4. Replace with manufacturer-recommended transmission fluid.
5. Reinsert the dipstick and start the engine, allowing it to reach operating temperature.
6. Recheck the fluid level and add as necessary.

3. Inspect and Replace Transmission Solenoids

Sub-steps:
1. Remove the transmission pan (if necessary) to access solenoids.
2. Disconnect the electrical connectors from the solenoids.
3. Use a multimeter to test each solenoid for proper resistance.
4. Replace any faulty solenoids with new ones.
5. Reassemble the transmission pan, using a new gasket to prevent leaks.

4. Check and Replace Transmission Mounts

Sub-steps:
1. Inspect the transmission mounts visually for cracks or wear.
2. Remove any damaged mounts using a socket set.
3. Install new mounts, ensuring they are torqued to the manufacturer's specifications.
