Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid level gauge, fluid transfer pump, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Replace Transmission Fluid

Check Fluid Level:
- Remove the transmission dipstick.
- Wipe it clean and reinsert it, then remove it again to check the fluid level.
- If low, proceed to add fluid.
Add Transmission Fluid:
- Use a funnel to add the appropriate type of transmission fluid as specified in the owner's manual.
- Start the engine and allow it to run for a few minutes, then recheck the fluid level.
Inspect Fluid Condition:
- If the fluid is dark, burned, or has a burnt smell, it should be replaced.

3. Replace Transmission Fluid and Filter

Drain Old Fluid:
- Locate the transmission pan and place a drain pan underneath.
- Remove the drain plug or pan bolts and allow the old fluid to drain completely.
Remove Transmission Pan:
- Once drained, remove the transmission pan completely.
- Clean the pan and magnet of any debris.
Replace Filter:
- Remove the old transmission filter and replace it with a new one.
- Install a new gasket on the transmission pan.
Reinstall Pan:
- Reattach the transmission pan and torque the bolts to the manufacturer's specifications.
Refill New Fluid:
- Use a funnel to refill new transmission fluid to the correct level.
