Solution

1. Preparation

• Tools Required: OBD-II scanner, transmission fluid, socket set, multimeter, torque wrench, fluid pump.
• Ensure the vehicle is on a level surface and securely supported with jack stands.
• Disconnect the battery to prevent any electrical issues during repairs.

2. Change Transmission Fluid

• Sub-steps:
  1. Remove the transmission pan bolts using a socket set.
  2. Carefully lower the pan to drain the old fluid into a pan.
  3. Replace the transmission filter; remove the old filter and install the new one.
  4. Clean the transmission pan and magnet, then reinstall the pan with a new gasket.
  5. Refill the transmission with new fluid using a fluid pump, ensuring to use the manufacturer-specified fluid.

3. Inspect and Replace Transmission Solenoids (if necessary)

• Sub-steps:
  1. Access the transmission solenoids by removing the necessary components (consult the repair manual for specific access points).
  2. Disconnect the electrical connectors from the solenoids.
  3. Use a multimeter to test the resistance of each solenoid; replace any that are out of specification.
  4. Reinstall the new solenoids and reconnect the electrical connectors.

4. Check Engine and Transmission Mounts

• Sub-steps:
  1. Visually inspect engine and transmission mounts for cracks or excessive wear.
