Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid, funnel, rags, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Fluid Inspection and Replacement

Check Fluid Level:
- Start the engine and let it warm up.
- With the vehicle in park, remove the transmission dipstick and wipe it clean.
- Reinsert and remove the dipstick again to check the fluid level.
Fluid Condition:
- Inspect the fluid color; it should be a bright red color. If it’s dark or smells burnt, it needs to be replaced.
Fluid Replacement:
- Drain the old transmission fluid using a drain pan.
- Replace the transmission fluid filter if applicable.
- Refill with the manufacturer-recommended transmission fluid using a funnel through the dipstick tube.
- Ensure the fluid level is within the specified range on the dipstick.

3. TCM and Sensor Check

Inspect TCM:
- Locate the transmission control module (usually under the dashboard).
- Check for loose connections or corrosion on the wiring harness.
Throttle Position Sensor (TPS):
- Disconnect the TPS connector.
- Use a multimeter to check the resistance; it should vary smoothly as the throttle is operated.
- Replace if faulty.

4. Engine Mount Inspection

Check Engine Mounts:
- Visually inspect the engine mounts for cracks or excessive wear.
- If mounts are damaged, replace them with OEM parts.
