ATS DIESEL’ HYDRAULIC TECHNOLOGY SHIFTS INTO HIGH GEAR

Dodge ‘Billet’ Transmissions Now Equipped With Hydro-Balanced Sleeve

Throttle Valves (TV Valves) in a transmission’s valve body control shift timing between gears through controlled flow of hydraulic fluid. Until now these valves have been known to have issues wearing out the inside of the bore in the valve body, which caused malfunction and improper shifts due to leakage of fluid. When using the modified-stock or oversized TV valves, increased line pressure caused hard and abrupt shifts. Despite all of the changes made in the past to the material from which the valve is made, the bore itself in the valve will wear and prevent proper (or any) movement of the valve. Issues have been present especially in the Dodge 48-RE Transmission. In 2005 Dodge changed the valve body casting material from quality aluminum to an inferior material that is very soft and prone to wearing out.
ATS has designed an innovative solution in our Dodge Ram transmissions using a unique ‘Hydro-balanced Valve and Sleeve’. By altering both the design and material of the valve itself, as well as placing a hardened sleeve in the valve body’s bore, the sticking issues are prevented. The valves in the ATS Valve Body perform extremely smoothly and operate as intended after extended use. Utilizing this new design valve and sleeve assembly allows the hydraulic flow to be altered providing a more aggressive line pressure slope while providing quality shifts and TCC (torque converter clutch) engagement.
The concept used by ATS is similar to that of a piston sleeve in an engine. By using high quality, hardened material, the lifespan of the moving component is greatly increased and the issue of a worn bore is eliminated. This technique further raises the functionality and quality level of the ATS Valve Body and Transmission system to an even higher level and is used in our Towing, Racing, and Stand-Alone-Programmable Valve Bodies.
