Continuous thermal cycling embrittles these plastic tanks, leading to fatigue fractures at the upper hose neck. More critically, early OEM assemblies are susceptible to internal transmission cooler barrier failures, allowing ethylene glycol to contaminate automatic transmission fluid and destroy the torque converter clutch friction linings in 722.6 transmissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upgraded performance unit features 100% aluminum construction with precision TIG-welded end tanks joined to an oven-brazed, high-efficiency 3-row core. By eliminating mechanical crimps and plastic resin components, it completely removes the risk of tank separation and internal fluid cross-contamination.
