Our Two Hydra-Test valve body testing machines are both computer controlled, which
is a must for today's electronically operated transmissions. One of the special features
of this system is the ability to run a fully automated shift sequence. We 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 Automatedsequence
can be set from 1 to 100 times, this is especially usefulwhen 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
second Hydra-Test has a 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 is collected on each valve body tested and
stored for reference
All Valve Bodies are checked and latest enhancement installed .Solenoids are cleaned
ultrasonically and tested on our sol ex 2000 prior re-assemble.
Linear solenoids such type as 55/50 are re-calibrated.
Linear solenoids fitted to valve bodies such as 09G/09K Clutch control adjustments
are carried out
