The Hydra-Test VBT emulates the work of the control unit of the car gearbox hydraulics. In the Hydra-test, the output oil lines that extend from the valve body and turn on certain packages of the frictions and other mechanisms in a gearbox have pressure sensors installed in them taking readings in every time unit. Once the information is obtained and processed, the results are put in the form of graphs and tables with data that can be compared with the results of benchmark tests conducted on new, working valve bodies. Proper analysis of these data can provide a complete understanding of the status of the valve body, and most importantly, it will help to localize the source of the problem, if the tests of the valve body under rebuilding were far from ideal.
