This part 2 is a conclusion to our 2-part insight into the Transmission Control Module / Mechatronics Units testing.

Car transmission technologies are developing at a growing rate and should be serviced with the help of more advanced and efficient diagnostic and repair equipment. Therefore, Cottingham Engineering specialists came up with the idea to refurbish old valve body testing machines (first of all, those running on VBDaq and E-ZEE Shift) for company’s customers or simply to buy unused Hydratest machines and find an appropriate application for them.

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.

While manual gearboxes utilize the clutch to shift speeds, automatic transmissions make use of a sophisticated hydraulic system for shifting, and the transmission solenoid is especially important for this process.

In December 2017 Cottingham Engineering LTD, owners of the Hydra-Test brand, launched their new concept named Hydra-Tested to give promotion and wider attention to the users of the Hydra-Test Valve Body testing equipment.
