Repair Instructions

Depending on the issue identified, follow these repair instructions:

  1. Fluid Change

    • If fluid condition is poor:

    • Replace gaskets or seals as necessary:
      • Remove the transmission pan if needed.
      • Scrape off old gasket material and clean surfaces.
      • Install a new gasket or seal.
      • Reinstall the transmission pan with specified torque settings on bolts.

  3. Addressing Codes

    • If error codes indicate a specific issue (e.g., solenoid failure), replace the faulty component:
      • Disconnect battery to prevent electrical issues.
      • Locate the solenoid or affected sensor, remove it, and replace with a new one.
      • Reconnect battery and clear codes with the OBD-II scanner.
