1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, torque wrench, replacement transmission fluid filter (if necessary).
• Disconnect the battery to ensure safety while working on electrical systems.

2. Addressing Fluid Issues

1. Check Fluid Levels:

   • Remove the transmission dipstick (if applicable) and check fluid levels.
   • Add transmission fluid if low, using the manufacturer-recommended type.

2. Fluid Condition:
