BD Diesel Transmission Cooler Bypass Valve Delete Kits

BD Diesel has been a leader in heavy-duty powertrain components since 1972. They focus on getting the most power and durability out of your diesel-powered truck—and to help eliminate costly transmission failure, they offer these transmission cooler bypass valve delete kits. The factory cooler valve can be stuck in recirculation mode if any type of debris jams the internal valve; this will increase temperatures dramatically and cause transmission failure. These cooler bypass delete valves always keep transmission fluid flowing to the cooler regardless of speed or load of the truck—ensuring your transmission will stay cool and eliminate costly repairs. Look to BD Diesel to push your truck to be all it can and should be. Order the kit recommended for your vehicle, engine, and transmission application.

ATS Diesel Performance Cooler Bypass Delete Kits

ATS Diesel Performance cooler bypass delete kits are designed to help keep your transmission cooler, while also protecting seals and ensuring a more trouble-free operation. Over time, the bypass can malfunction and cause fluid to bypass the cooler. Eliminating this component with an ATS delete kit assures that all the fluid flows through the cooler. Order the model recommended for your vehicle, engine, and transmission application.

Sonnax Automatic Transmission Cooler Bypass Valve Kits

Sticking of bypass components, spring relaxation, or poor ball seat in Ford 4R100 and E4OD units will allow the bypass to open at lower cracking pressure. This reduces TCC (Torque Converter Clutch) apply pressure, cooler flow at the overdrive section, and radiator flow responsible for heat transfer. Sonnax automatic transmission cooler bypass valve kits allow the bypass valve assembly to be rebuilt, salvaging the OE fittings and maintaining cracking pressure at 70 to 75 psi. Features: * Hardened steel T-valve provides secure check ball seat and adequate bypass flow * New spring cracks open at 70 to 75 psi to provide lube if cooler is blocked or restricted * Hardened alloy steel check ball resists damage * Seven new O-rings provide positive seal for cooler circuit * Drop-in Zip Valve parts install quickly and easily Contents: * T-valve * Spring * Check ball * O-rings -- One small -- Two medium -- Two large -- Two extra-large

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

Tremec Magnum-F Manual Transmissions

Tremec introduces the Magnum-F 6-speed manual transmissions for fourth-generation Camaros and Firebirds. Designed to replace T-56 transmissions in 1998-2002 GM F-body cars, the Magnum-F leverages Tremec's pervasive TR-6060/Magnum architecture in order to provide fourth-gen enthusiasts significantly improved performance and relief from a shrinking pool of quality T-56 replacement parts. Born in the vacuum created by the release of the original T-56 Magnum (now known simply as 'Magnum') back in 2009, the Magnum-F fills a longstanding void in the overall Magnum line with regard to shifter locations—addressing not only LS1-powered '98-'02 F-bodies, but several other applications that utilize a similar shifter position. Beneficiaries include third-generation F-bodies, LT1-powered fourth-gens, LS-swapped late models of all varieties, and sport compact applications such as A80 Supras, FD RX-7s, and more! Where the original Magnum shifter locations may prove too far forward, and the extended length Magnum XL's too far back, the Magnum-F's in-between position often proves to be just right. Inside, the Magnum-F benefits from the same durable componentry found in many of today's hardest hitting OEM muscle and sports cars. Over the T-56, the Magnum-F transmissions boast increased face-width on all gears, a robust combination of double and triple cone synchronizers, enhanced webbing in the main case, provisions for a cooler circuit, and more! Tremec also took the opportunity to upgrade the shifter to an isolator-type unit, like that found on its Magnum XL. The shifter reduces in-cabin noise and vibrations, while at the same time providing the precise and communicative shift feel that all Magnums are known for. And, like all Tremec aftermarket transmissions, the Magnum-F is made from 100 percent brand-new OEM-quality content. Models with different gear ratios are available. Additional notes: * Close Ratio version for high performance street and road racing * 700 lbs.-ft. of torque capacity * Reasonably light at 135 lbs. dry * Multiple shifter locations and dual speedo pickups for unmatched versatility * Choice of two different gear ratio sets with unique double overdrive ratios * Incredibly short, extremely low-effort shift throws, with crisp, precise engagement * Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more

Boss Hog Street Bandit Torque Converters

Torque converters are considered one of the most mysterious mechanical components in today's vehicles. They function like a clutch, and keep the engine running even when the vehicle comes to a halt. By designing the stall speed to match both the engine and desired stall speed, ACC Performance converters help low-end idle speeds, improve performance, and acceleration. ACC Performance Products has emerged as an out-right leader in torque converters and here's why: * Boss Hogs are welded, not furnace-brazed; furnace brazing is not the best way to adhere torque converter components, it will erode and ruin the stators and all rotating parts * Industrial Torrington bearings handle more torque than smaller, uncased needle bearings * Aircraft aluminum washers instead of fiber washers put more horsepower and torque directly to the ground * ACC converters are hand-built and tested to ensure that you get the best converter money can buy * With returns below one percent, you are assured of the highest quality parts available * Street Bandit converters are designed to handle as much as 650 hp * Custom-engineered turbine hubs maintain the highest quality, strength, and durability * Stators are built with high-flow vents and channels for greater cooling to handle greater power and higher temperatures * Engineered with a single bolt pattern that makes ACC converters surprisingly light to free up your motor and allow it to gain rpm quicker Notes: * Boss Hog Street Bandit torque converters are not designed to handle the extreme shock and abuse of nitrous oxide or trans-brakes * It is imperative that a transmission cooler be added with any torque converter that is rated over stock stall speed
