• 🧯 If your truck does not use a transmission cooler, you can leave the ports unconnected — they will NOT leak.

🔧 Warranty Warning:
If the transmission oil cooler is damaged during installation (from over-tightening, cross-threading, or stripping), the warranty will be void.
👉 Use correct torque and installation technique to preserve coverage.
