A number of sensors are required to make the 722.9 transmission work properly. Like speed sensors for example. However here, the speed sensors and a number of other important electronic components are installed on a separate 722.9 conductor plate. If just one sensor goes bad, you have to replace the entire unit. For years, you could only obtain a Mercedes 722.9 conductor plate from a Mercedes dealer. That was obviously a very expensive proposition. But now you can buy a completely remanufactured Mercedes 722.9 valve body, or just the Mercedes transmission conductor plate.
The problem with repairing a 722.9 valve body is that you don’t really know what kind of stress and extreme temperature changes they have been subjected to. This is why many people simply install a remanufactured 722.9 valve body, to eliminate the threat of the unknown. Companies like Street Smart Transmission use state of the art equipment to completely remanufacture the valve body. This is not like rebuilding, where new components are simply installed into the existing valve body. They use specialized equipment to analyze each valve body to see if it has been cracked or warped. A mechanic does not just simply eyeball it, a machine does the inspection, and even checks the tensile strength of the metal to make sure that it meets the original OE specification.

Once a casting has been selected for the build, all of the bores are modified, to make sure that the valves will function the way they were intended to. Then every single component from the check balls, to the valves, pistons and springs are tested and/or replaced. After that process is complete and quality inspected, they install all new solenoids (they also bench test them prior to installation), speed sensors and pressure switches. The finished product is then put on a Superflow AXILINE Valve Body Tester, which can simulate actual road conditions. This allows their ASE certified techs to verify the functionality, and make any adjustments or fixes before they ship it out to the customer. Street Smart Transmission also gives it a 1-Year/No Hassle Warranty, which makes getting a remanufactured 722.9 valve body almost a no-brainer.
