Valve Body Tester
Valve Body testers serve to transmission shops as advanced tools for diagnosis of this complex automatic transmission part. The aim of any unit placed in this section is in finding the exact source of problems within a Valve Body by comparing its performance against the benchmark data. Used transmissions and rebuilt transmissions require guarantees of high quality of transmission rebuild and this involves Valve Body repairs. The systems implemented capture pressure and current values, allow drawing charts for easy visual perception and do many more than that to advance any transmission rebuilding business to a newer standard of quality

The Go4Trans Team is
happy to present to you part 1 of the 2-part research over the testing methods
of TCMs / mechatronics units.
This part 2 is a conclusion to our 2-part insight into the Transmission Control Module / Mechatronics Units testing.
we talk about testing, we not only need to understand why we are testing it,
but more importantly, the
how do we test it. The “why” is fairly
straight forward, as we want to determine if it is still functioning properly
and that we can reuse it. The how to
test it might not be as clear, and there are multiple methods of how to test,
and sometimes opinions on how to test that are not always accurate.
Solenoids can become a hot topic of conversation at transmission shops. Some say the best way is to treat them like a soft part and replace them on every rebuild, whereas other say that you can check them and only replace the ones that are faulty or worn out. The first group will say any reuse leaves you open to
Over the years I have heard several different philosophies when it comes to flushing and cleaning solenoids. Most hydraulic solenoid test machines have either flush mode or an external cleaning system for solenoids. It is easy to think of it like you are putting the solenoid in a dishwasher of sorts and
Over the past few decades valve bodies have become the single most complicated part of the transmission. The control has become very complex as we’ve gone from simple 4 speeds to electronically controlled 6, 7 and now even 10 speeds. They have also
The valve body is a hydraulic “controller” (also called as a “transmission brain”) consisting of valves, solenoids, sensors batteries and attached to them are passages and channels, which guide the flow of ATF to various valves with the purpose to activate required clutch and shift the gear properly according to the driving situation.
