Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, multimeter.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to ensure safety during electrical work.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If fluid is low, add the recommended type of transmission fluid as specified in the owner's manual.
If fluid is dirty or burnt, proceed to replace the fluid:
- Remove the transmission pan using a socket set.
- Clean the pan and replace the filter if applicable.
- Reinstall the pan with new gasket material; torque bolts to manufacturer specifications.
- Fill the transmission with new fluid through the dipstick tube.

3. Inspect and Replace Transmission Mount

Locate the transmission mount and visually inspect for cracks or wear.
If damaged, remove the bolts securing the mount to the transmission and the chassis.
Replace with a new transmission mount and torque bolts to manufacturer specifications.

4. Electrical Inspection

Inspect the wiring harness connected to the TCM for any signs of wear or damage.
Use a multimeter to check the voltage and ground at the TCM connector; ensure readings are within specifications.
Repair or replace any faulty wiring or connectors.
