   • Use the provided mounting hardware to secure it in place.

2. Connect the Cooler Lines:

   • Attach the new transmission lines to the cooler, ensuring they are securely fastened to prevent leaks.
   • Follow the provided diagram in the kit for correct routing.

Practical Tip

• Use thread sealant on fittings to ensure a tight seal and prevent leaks.

Step 4: Refill Transmission Fluid

1. Reconnect the Transmission Lines:

   • Ensure all connections are tight and secure.

2. Refill the Transmission:

   • Use the appropriate transmission fluid as specified in your owner’s manual.
   • Fill until the fluid reaches the proper level on the dipstick.

3. Reconnect the Battery:

   • Reattach the negative battery terminal.

Step 5: Test the Installation

1. Start the Engine:

   • Allow it to idle and check for any leaks around the cooler and lines.

2. Check Fluid Levels:

   • After a few minutes of running, recheck the transmission fluid level and top off if necessary.

3. Take a Test Drive:

   • Go for a short drive to ensure everything is functioning properly.

Common Pitfall

• Monitor the transmission temperature gauge during your test drive to ensure the cooler is effectively managing the temperature.
