In 2006, Power Test Inc purchased the transmission and hydraulic testing equipment division of AIDCO International. AIDCO set the standard for hydraulic test equipment since its introduction to the market in the mid-1960s. The product line has been expanded and refined to become AIDCO Test Systems. AIDCO has been successful through the combination of a solid customer base and pays attention to the needs in an ever changing market. The AIDCO name was re-established as a leader in the transmission and hydraulic component testing industry.
