Sonnax 72760-01K Thermal Bypass Eliminator Kit

The Sonnax 72760-01K Thermal Bypass Eliminator Kit provides a reliable solution for preventing transmission overheating caused by stuck OE thermal bypass valves in Chrysler RFE, Aisin Seiki AS69RC, and ZF8HP45/70 transmissions. This kit allows reuse of the OE cooler block with built-in pressure relief while ensuring continuous fluid flow through the cooler.

Key Features:

• Replaces faulty OE thermal bypass valve with a permanent plug solution
• Ensures continuous fluid flow through the cooler to prevent overheating
• Includes O-ring sealed plug for secure, leak-free installation
• Compatible with OE part numbers: 52014762AA, 68186711AB, 68291739AA, and 68210018AA
• Drop-in installation—more cost-effective than replacing entire OE cooler bypass valve
• Fits Chrysler transmissions: 45RFE, 545RFE, 65RFE, 66RFE, 68RFE, 845RE
• Fits Aisin Seiki AS69RC and ZF8HP45/ZF8HP70 transmissions

The OE thermal bypass valve in these transmissions is known to stick in recirculation mode, preventing fluid from flowing through the cooler and causing dangerous overheating conditions. This eliminator kit permanently solves the problem by removing the bypass function and maintaining optimal transmission temperatures under all operating conditions.
