Protect your transmission from both under and over-cooling! 🛡️ See how the Hayden Patented Transmission By-Pass Cooler manages fluid flow: • Cold: Fluid flows through the by-pass row to warm up quickly. • Hot: A thermal valve closes the by-pass, ensuring full flow through the cooling rows for maximum heat transfer. This smart design prevents fluid stagnation and keeps your transmission at the optimal operating temperature! #HaydenCooler #TransmissionProtection #OptimalTemp #Automotive | Hayden
