Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid, multimeter, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening any components.

2. Addressing Transmission Fluid Issues

Check Fluid Level:
- Park the vehicle on a level surface and engage the parking brake.
- With the engine running, check the transmission dipstick.
- If low, add the correct type of transmission fluid (refer to owner's manual for specifications).

3. Inspect and Replace Transmission Mounts

Remove Old Mounts:
- Lift the vehicle securely and remove the undercarriage protection if present.
- Use a socket set to remove the bolts securing the transmission mount.
Install New Mounts:
- Position the new mount in place and secure it with the bolts.
- Torque the bolts to the manufacturer’s specifications.

4. Fixing Electrical Issues

Inspect and Repair Connections:
- Locate the wiring harness connected to the transmission.
- Check for frayed wires, corrosion, or loose connectors.
- Clean or replace any damaged connectors to ensure proper electrical contact.

5. Testing and Adjustments

Perform Transmission Adaptation:
- If applicable, perform a transmission adaptation process using a scan tool to reset shift points and learn behaviors.
