Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, multimeter, transmission fluid, and a new transmission filter (if necessary).
  • Safety: Disconnect the battery before starting any electrical work.
2. Check and Replace Transmission Fluid
  • Remove the transmission fluid pan using a socket set.
  • Drain the old fluid into a suitable container.
  • Inspect the transmission filter; replace it if clogged.
  • Clean the pan and magnet inside it to remove any debris.
  • Refill the transmission with the correct type and amount of new fluid (refer to owner’s manual for specifications).
3. Inspect and Repair Cooling System
  • Locate the transmission cooler and inspect for blockages or leaks.
  • If damaged, replace the cooler by disconnecting the fluid lines and mounting bolts.
  • Ensure proper installation and tight connections to avoid future leaks.
4. Replace Transmission Temperature Sensor (if faulty)
  • Locate the transmission temperature sensor, typically near the transmission housing.
  • Disconnect the electrical connector and remove the sensor using a socket.
  • Install the new sensor and reconnect the electrical connector.
5. Reassemble and Recheck
  • Reattach the transmission fluid pan, ensuring the gasket is properly seated.
