Cottingham Engineering Expands its Range of Services
Hydra-Test valve body testing units have been widely used by transmission repair specialists worldwide for more than two decades. Thanks to high quality of Cottingham Engineering products, the early models are still widely used by automatic transmission repair experts. However, 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.
A valve body is one of the most important
components of automatic transmissions. It is responsible for redistribution of
ATF flow and its pressure rates. The valve body is also considered to be one of
the most complicated elements of the automatic transmission. And, in fact, it is
so, since the valve body design includes a metal valve plate with numerous
channels (with installed control
valves), different springs and plungers, sets of sensors and solenoids
responsible for proper operation of the gearbox.

Problems with the valve body may lead to serious repair of the whole transmission unit. Issues with this element may be caused by different reasons. Vacuum testing equipment will help to reveal major problems within the valve body, but more subtle problems are likely to remain unrevealed.
That is why the diagnostics and repair of valve
bodies must be performed by professional specialists who have the required skills and
experience. In addition, workshops require special advanced equipment, which
will help to perform different tests
and accurately detect even the slightest deviations from standard operational
characteristics of the valve body. Therefore,
Cottingham Engineering offers to
its customers (professional transmission rebuilders) the opportunity to
refurbish their old Hydra-test machinery, so it will be upgraded to match the
capacity of HT-VBT DELUXE, the
flagship machine of
Cottingham Engineering which allows gearbox rebuilders to execute quality
testing of the most in-demand modern
valve body units and individual solenoids, whilst solutions for older valve body makes are provided
too.

In comparison to older valve body testing
solution,
HT-VBT Deluxe is equipped with HTC-K Controller and, obviously, fully digital
interface. The Deluxe unit was developed with an improved control over heating
element and dual monitor so it can withstand extensive temperatures in the
process of testing. It also has enhanced pressurizing pump capacity.
Thanks to introduction of HTC-K Controller, the Deluxe model provides advanced methods of PMW solenoid testing and higher frequency of data capture (500 Hz). The process of the Controller operation is notable for its user-friendliness (as well as ease of software update).

Summarizing the above, today Cottingham
Engineering offers
3 new service options:
- Trade-in deal, i.e. when buying HT-VBT Deluxe customers can trade in older Hydra-test machinery to get an amount off the deal price.
- Upgrade of any older Hydra-Test valve body testing machines to a high standard by the team of professionals at the company’s facility in Kettering, England.
- Sale of any unused Hydra-Test equipment, so it can be refurbished and put to good use somewhere in the world.
