*TOWING EDITION* Valve Body Features:
Valves (TV Valve) in a transmission’s valve body control
shift timing between gears through the constriction of hydraulic
fluid. The TV valve also controls the line pressure required
to clamp the clutch pack and band inside the transmission. Until
now these valves have been known to have issues sticking inside
the bore in the valve body, or wearing out due to friction,
which causes malfunction and improper shifts.
- Improved shift
- Increased reliability
- Optimized for
use with exhaust brake
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 movement of the valve. Especially in the
Dodge automatic Transmission, Dodge manufactures the stock
valve body from a very cheap mystery 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 shape 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 Torque converter clutch engagement. When using
the stock TV valve or oversized TV valves increased line pressure
caused hard and abrupt shifts.
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.
