Transmission Control Unit; Model TR-C75

TCU Model TR-C75The TREMEC Model TR-C75 Transmission Control Unit (TCU) integrates electronic controls to achieve better fuel economy, reduced engine emissions and improved shift feel. The module is primarily targeted at high-end dual clutch transmission and automated manual transmission control.

Built around a high-performance multi-core microcontroller, it excels in computationally intensive model-based applications that need advanced safety architecture.

The control module’s output architecture supports redundant switching of output banks that maximize limp-home capabilities. In addition to standard diagnostic features, current outputs of the control module support detection of solenoid function and provide full control over dithering frequency and amplitude.

Applications are supported by a software environment that abstracts the low level and communication hardware. The device supports standard communication, on-board diagnostics and diagnostic protocols. Optionally, applications may be supported by AUTOSAR 4.0, the standardized automotive software architecture.
