- If cracked, replace the transmission pan.
Replace Transmission Fluid
- Drain old transmission fluid and replace with new, suitable fluid.
- Use a funnel to refill through the dipstick tube.

3. Repairing Coolant Leak

Inspect Hoses and Connections
- Check all hoses for cracks or damage.
- Replace any damaged hoses with new ones.
Replace Radiator Cap
- If the cap is worn or damaged, replace it to ensure proper pressure.
Flush Cooling System
- Drain the old coolant and flush the system with a coolant flush solution.
- Refill with the manufacturer-recommended coolant mixture.

4. Repairing Power Steering Fluid Leak

Inspect Power Steering Lines
- Check for cracks in the power steering lines and the reservoir.
