Pacific Performance Engineering Transmission Fluid Bypass Valves
Pacific Performance Engineering offers automatic transmission fluid bypass valves for a variety of applications. The OEM part has restrictive internal passages; and when the OEM valve fails in the open position, transmission fluid doesn't reach your cooler. This can be caused by mechanical failure or debris. The result of stock valve failure can cause the transmission to dangerously overheat. Without properly cooled transmission fluid, the demands of towing and rigorous stop-and-go driving conditions shorten the life of transmission components. This PPE bypass valve eliminates the mechanical valve—which maximizes fluid flow from the transmission cooler. For further protection, a Neodymium magnet-equipped service plug has been added. The removable plug traps ferrous debris and can be accessed to remove particles from the system. The factory part does not have this feature. Additional notes: * Billet aluminum construction * Neodymium magnet-equipped service plug with O-ring * Easy to install * Limited lifetime warranty

RevMax Transmission Cooler Thermostatic Bypass Upgrades
Completely re-engineered, these RevMax transmission cooler thermostatic bypass upgrades are a direct bolt-in replacement. No lines are cut, nothing is altered. Simply disconnect your old lines and install them onto your new RevMax bypass. Utilizing RevMax's ZeroStat Technology, these billet 6061 aluminum cooler thermostatic bypass upgrade modules completely remove the orifice restriction for full cooler flow all the time. This equates to lower operating temperatures and helps to prolong the transmission's life. Order the model for your application. Features and benefits: * RevMax's ZeroStat patented technology provides increase in cooler flow due to the elimination of the orifice bottleneck located in the factory part * Direct bolt-in replacement—no lines are cut, nothing is altered, simply disconnect your old lines, and install them into the RevMax new bypass * There is no thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction * Instead of closing off cooler flow when the transmission is cold and making your transmission generate unneeded heat that is hard to shed later; RevMax bypass allows your cooler to immediately begin cooling transmission and not waiting for it to get hot, just to try to cool it later * You cannot properly flush your cooler lines without the aid of a hot flush machine that can get hot enough to open the bypass valve up but with the RevMax bypass upgrade you can use room temperature fluid to clean out your cooler anytime you wish without any special tools! * Moules with integral aluminum cooling fins aid in passive cooling of the block and fluid

Improved Racing Oil Cooler Thermostats
Improved Racing oil cooler thermostats fit your cooling system with a compact, patent-pending design and function that are crucial to engine performance. These Flow Series Motorsport (FSM) oil thermostats ensure a low-pressure drop by placing the bypass valve mechanism completely out of the primary oil flow, while performing the critical function of bypassing the oil cooler until the oil has reached its minimum operating temperature. This removes the danger of over-cooling the oil and delaying engine warm-up, resulting in horsepower loss, excessive engine wear, and reduced gas mileage. These high-flow thermostats are crafted from aluminum, and then anodized for added durability and looks. They offer a lightweight universal solution to be used with any oil cooler on any vehicle or application.
