- Locate the transmission dipstick and check fluid levels.
- If low or dirty, drain the old fluid and replace it with the manufacturer's recommended transmission fluid.
- Refill to the appropriate level using a funnel.

3. Exhaust System Repair

Examine the entire exhaust system for any loose or damaged components.
Tighten any loose bolts or clamps.
Replace any damaged sections of the exhaust system using appropriate gaskets and clamps.
