Delphi On/Off Transmission Actuators
Delphi On/Off Transmission Actuators control fluid flow in
automatic transmissions to enable reliable shift control and torque
converter clutch control. They feature a simple, low-cost design
and are available in two-port or three-port designs. Both designs
can be supplied as a normally closed or as a normally opened
device to suit customer requirements.

Reduced manufacturing variation provides consistent
performance characteristics
Feature simple hydraulic and magnetic designs that are robust
to small contamination (less than 250 microns)
Optional filters enable robust performance to large
contamination (larger than 250 microns)
Designs optimized to minimize the number of components
Robust designs proven in the field for low warranty
Mounting configurations available with brackets, clips or twistlock features

Typical Applications

Delphi On/Off Transmission Actuators are
available in various package sizes and
configurations to meet customer requirements.

Delphi On/Off Transmission Actuators are suitable for most automatic transmission applications in
passenger cars and light trucks as well as other larger vehicle programs. They can also be used for other
automotive or non-automotive applications that require flow control of hydraulic fluid.

Performance Advantages
The simple hydraulic and magnetic design of Delphi On/Off Transmission Actuators makes them especially
robust to small particle contamination (less than 250 microns). Delphi also offers optional filters to make
the actuators robust to large particle contamination (greater than 250 microns). Delphi's unique
manufacturing processes reduce performance variation, thus providing consistent performance
characteristics. Delphi offers a broad product and process technology base to provide customers with
creative designs that will meet each application's unique requirements.
