Hydratest automatic transmission test unit

The Hydra-Test machine has undergone several changes since its conception, and today's model shows our commitment to quality and the ever increasing demand for better and more comprehensive test equipment.

The new Hydra-Test valve body testing machine is now computer controlled, which is a must for today's electronically operated transmissions. The control system is very user friendly, with an understandable interface and all the information required; all you need is a PC to run the software and a 12v power supply to run control system.

One of the special features of this system is the ability to run a fully automated shift sequence. The user can set the shift pattern by spacing the shift timing and setting the amount of times the shift sequence will cycle, all at the click of a mouse. The valve body will then cycle up and the down through all gears, including TCC lock-up. This Automated sequence can be set from 1 to 100 times, this is especially useful when trying to find a fault that only occurs on the vehicle after the valve body and solenoids have been run for a period of time.

The system can extensively test PWM (pulse with modulation) solenoids, these are usually Pressure Regulator or TCC Lock-up, although PWM solenoids are being used more frequently in smoothing shift control. A duty cycle ramp bar on the screen shows the effect of this type of solenoid when energized. Solenoids can be individually selected to assess correct function, I.e. Current draw or resistance. They can also be automatically tested for a pass/fail condition.

The computer control system can also be used on any valve body machine, or to operate the transmission while mounted to a dynamometer. The duty cycle on the pressure regulator solenoid can be selected and locked to choose the pressure cut back required to give smooth gear-shift.

The Hydra-Test can also be adapted to run a full data acquisition system. This is done with the attachment of pressure transducers coupled to the gauge lines, and then the electronic wires attached to the control board. Live data can then be collected, stored and printed for the ultimate in valve body testing
