Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, transmission fluid, catch pan, rags.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Replace Transmission Fluid

Check Fluid Level
- Start the engine and let it warm up.
- Pull the transmission dipstick and wipe it clean. Reinsert and remove it again to check the fluid level.
Drain Fluid
- Place a catch pan under the transmission pan.
- Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the old fluid.
Inspect Fluid
- Examine the drained fluid for burnt smell or metal shavings.
- If the fluid is dark or has a burnt smell, replacement is necessary.
Replace Filter (if applicable)
- Remove the old transmission filter (if equipped) and replace it with a new one.
Refill Transmission Fluid
- Reinstall the transmission pan and torque bolts to manufacturer specifications (typically around 10-12 Nm).
- Using a funnel, refill the transmission with the appropriate type of fluid (consult owner’s manual for specifications) through the dipstick tube.

3. Check for Leaks

Start the engine and allow it to reach operating temperature.
Inspect the transmission area for leaks around the pan and cooler lines.
Tighten any loose bolts or fittings as necessary.

4. Test Drive

Conduct a test drive to ensure smooth shifting and to monitor for any unusual smells or noises.
Check the transmission fluid level again after the test drive and top off if necessary.
