When this valve fails closed, it completely blocks automatic transmission fluid (ATF) flow to the transmission oil cooler \/ heat exchanger. With nowhere for the heat to go, your transmission will quickly overheat and internally cook itself.\u003c\/p\u003e\n\n\u003cp\u003eTo make matters worse, the factory transmission temperature warning light won't illuminate until your fluid reaches \u003cstrong\u003e240°F\u003c\/strong\u003e—a temperature high enough to cause rapid fluid breakdown, clutch slippage, and irreversible internal gear damage. Worse yet, Chrysler does not sell the factory valve as a standalone replacement part; fixing it through the dealer requires purchasing the entire cast aluminum heat exchanger housing.\u003c\/p\u003e\n\n\u003ch2\u003eThe Solution: ATS Billet Thermal Bypass Upgrade\u003c\/h2\u003e\n\u003cp\u003eThe ATS Thermal Bypass Valve Insert eliminates the failure-prone factory mechanism, ensuring continuous, unrestricted fluid flow to and from your transmission cooler.
