Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid catch pan.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level.
2. If low, add the appropriate type of transmission fluid (consult the owner's manual for specifications).
3. If the fluid is dirty or burnt, drain the fluid using a fluid catch pan.
4. Remove the transmission pan (if applicable) and replace the filter.
5. Reinstall the pan with new gasket and torque bolts to manufacturer's specifications.
6. Refill the transmission with the recommended fluid.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Visually inspect the transmission mounts for cracks or excessive wear.
2. If damaged, use a socket set to unbolt and remove the old mounts.
3. Install new mounts and torque to the specified values.
4. Recheck the alignment of the transmission.

4. Test and Replace Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids (consult service manual for location).
2. Use a multimeter to test each solenoid for resistance according to specifications.
3. If a solenoid is faulty, remove it by unbolting and disconnecting the electrical connector.
4. Install the new solenoid and ensure proper connection.
