About Hydra-Test USA

Hydra-Test is a worldwide renowned brand that unites several test equipment solutions intended for top-class Automatic Transmission and Valve Body rebuilding. From mid 1990s and on, our products have been supplied to large remanufacturing businesses from USA and Western Europe, international OEM companies, as well as medium-scale and family-owned repair shops from all across the globe.




The top of the line machine is HT-VBT Deluxe, which allows professional rebuilders worldwide to conduct thorough testing of the most popular modern Valve Body models and individual solenoids. We provide the most expanded range of ready testing solutions and we constantly add new plate developments to the array, including most popular new US domestic models, globally popular CVT’s and DSG’s.

A more recent addition to the product range is HT-SOL, which is a stand-alone bench-type tool engineered for comprehensive high temp testing of transmission solenoids.

The HT2000 unit completes the Hydra-Test range; it is a portable solution designed to check automatics’ internal clutch and brake circuit integrity.
