Engine and Chassis Dynamometers, Transmission
Test Stands, & Data Acquisition Systems and Controls
Producing some of the world's finest dynamometers and equipment since 1976.




In 2006, Power Test purchased the transmission dynamometer and hydraulic testing equipment division of Aidco International. The Aidco name has been recognized as a world leader in the design and manufacture of transmission dynos and test stands. Power Test has expanded its product offerings with the addition of the AIDCO Test Systems hydraulic test stands, transmission dynamometers, and valve body test stands for mass-transit, heavy duty, off-highway and military applications. As a result, Power Test is now your one-source dynamometer provider for testing your principle power train components and vehicles.
AIDCO Test Systems offers the latest in modern, electric motor and hydrostatically-driven transmission dynos and test stands. All transmission dynamometers feature air-cooled eddy current absorbers (optional with model 900), resulting in minimal test cell noise and reduced maintenance.
Featuring the most advanced technology on the market today, the AIDCO 900-Series Transmission Dynamometer and Hydraulic Test Center is used for testing hydraulic pumps, motors, cylinders and valves, as well as power shift and automatic transmissions, and torque converters.
For nearly 40 years the AIDCO 850-Series Transmission Dynamometer and Hydraulic Component Test Stand has been the industry standard for testing of a broad range of sophisticated off-highway power shift and automatic transmissions and hydraulic pumps, motors, cylinders, valves, and torque converters.
The Model 850M Transmission Dynamometer and Hydraulic Component Test Stand has been developed to meet the transmission dyno and hydraulic component testing needs of military repair facilities worldwide.
Available in both electric motor and hydrostatically-driven versions, the AIDCO Model 450E and 450 Transmission Dynamometer Test Stands are designed for automatic transmission dyno testing and for testing power shift transmissions used in commercial applications built by Allison, ZF, Voith, and Renk, as well as most military transmissions.
The AIDCO Model 255 Valve Body Test Stand is used to calibrate and test automatic transmission valve bodies and governor assemblies (with optional governor drive assembly).
AIDCO Test Systems is now offering the new Electronic Shift Console (ESC) and PowerNet TD Data Acquisition and Control for transmission dynamometers and test stands.
The AIDCO Electronic Shift Console (ESC) provides electronic automatic transmission dyno shifting capabilities for Allison, ZF, Voith, and Renk transmissions, all in a durable, portable cart.
Based on the popular PowerNet Data Acquisition and Control System, PowerNet TD is available for all AIDCO transmission dynos and hydraulic component test stands.
