The AIDCO 550E-Series is our top of the line, dedicated, transmission test stand.  It’s a comprehensive test system with everything needed for testing automatic or power shift direct and remote mounted transmissions and torque converters used in commercial or off-highway applications. Based on the proven performance and reliability of our popular Model 450E transmission test stand, this quiet, compact test system keeps vehicle downtime to a minimum by greatly reducing critical failures on the road or in the field. In most cases, performance verification testing on this machine will eliminate the cost of additional dis-assembly and repair for rebuilt or serviced components.
