VALVE BODY TESTING

Valve body testing for automatic gearboxes is a critical process that ensures the smooth operation and reliability of your transmission systems. At The Gearbox Centre, we specialise in precision testing services that assess the performance and durability of valve bodies, which are essential components in automatic transmissions. Our advanced testing procedures include rigorous pressure testing, flow rate analysis, and functional evaluations to verify that each valve body meets industry standards and operates flawlessly under varying conditions. By ensuring optimal fluid control and seamless gear shifting, our testing services help prevent transmission failures, reduce maintenance costs, and extend the lifespan of your gearbox systems. Trust us to deliver accurate and dependable results that keep your automatic transmissions running at peak performance.

SOFTWARE

The Hydra-test in house developed software allow a us to run a series of tests to check the performance of a valve body at various gears and pressures for proper operation. Simply put, We can emulate transmission performance of the actual vehicle. Hydra-test have diligently written scripts for all supported valve bodies that the controller uses to perform a standard test sequence to the unit under test. By running a used valve body through a series of carefully written steps and recording the pressures, the system gives the us a graphical display of the unit under test compared to an original new valve body of the same model. This comparison makes it possible for us to determine the exact source of valve body problems – be it a damaged solenoid, a worn valve and bore, or plunger.  

Library of Reference Results

The vast experience of the Hydra-Test team collected over the years has allowed them to accumulate a large database of test results. Based on this, they have created an extensive library of reference results, which include tests for all of the common automatic transmission models available in the market today. This library allows us to successfully be able to test and qualify solenoids. We are given a vast library of good test samples and statistics for scrutiny for any unusual “non-standard” behaviour of tested solenoids. This significantly reduces the rejection of “suspicious” solenoids, giving us confidence in the results that are achieved.
