Solution

1. Preparation

• Gather tools and components.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Check and Replacement

• Sub-steps:
  1. Remove the transmission dipstick and check fluid level.
  2. If the fluid is low, top it up with the manufacturer-recommended transmission fluid.
  3. If the fluid is dark or smells burnt, drain the transmission fluid using a drain pan.
  4. Replace the filter if applicable, and refill with new transmission fluid.
• Tools Required: Transmission fluid, funnel, drain pan, socket set.
