Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check fluid level.
If low, add the manufacturer's recommended transmission fluid (refer to the owner’s manual).
If fluid is dirty or burnt, perform a transmission fluid change:
- Drain the old fluid from the transmission pan.
- Remove the transmission pan (use a socket set).
- Replace the transmission filter.
- Reinstall the pan with new gasket and torque to manufacturer's specifications (usually around 12-15 lb-ft).

3. Inspect and Replace Transmission Mounts

Locate the transmission mounts; there may be one or more.
Use a jack to support the transmission.
Remove the bolts securing the mounts (use a socket set).
Replace with new mounts and torque to specifications.

4. Test and Replace Transmission Solenoids (if necessary)

Disconnect the transmission wiring harness.
Remove the transmission pan again if solenoids are located beneath it.
Remove the faulty solenoids (use a socket set) and replace with new ones.
Reinstall the pan and torque to specifications.

5. Final Assembly

Reconnect the battery.
Start the engine and allow it to warm up.
Check fluid levels once more and add if necessary.
