1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan, funnel, multimeter, replacement transmission fluid, and filter.
  • Safety Warnings: Ensure the vehicle is on a level surface and the engine is off before beginning work. Disconnect the battery before working on electrical components.
2. Change Transmission Fluid
  1. Elevate the Vehicle: Use a jack to lift the vehicle securely and support it with jack stands.
  2. Drain Old Fluid:
    • Place a fluid catch pan under the transmission pan.
    • Remove the transmission pan bolts with a socket set and carefully lower the pan to drain the old fluid.
  3. Replace Filter:
