3. Check and Replace Transmission Fluid

Step 1: Locate the transmission dipstick or fill plug, depending on the transmission type.
Step 2: Check the fluid level; if low, add the manufacturer-recommended transmission fluid.
Step 3: If the fluid is dark or has a burnt smell, drain and replace it with new fluid.
Tools Required: Torque wrench, fluid pump, transmission fluid.

4. Inspect Power Steering System

Step 1: Check the power steering fluid level; top off with the recommended fluid if low.
Step 2: Inspect the power steering pump for leaks or unusual noises.
