Transtar Industries has reached a long-standing partnership agreement with Sonnax and Rostra Powertrain Controls, subsidiaries of Marmon Transmission Group. While details of the deal are still kept secret, the prolongation of this fruitful partnership is great news for the whole transmission aftermarket industry and in particular for repair shops, which get a reliable access to the top-quality auto components, including driveline and high performance.

Within the scope of the environment-oriented initiative, Sonnax will stop including printed guidelines/manuals with a wide range of products. Starting in spring 2019, approx. one thousand products will be sold without paper manuals.

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.

Sonnax Zip Kits commonly deal with key sources of valve body breakdowns and prevent pressure drops in the gearbox. The new ZF8 Zip Kit is manufactured to eliminate primary causes of pressure drop issues in gearboxes ZF8HP45/55/70.
