Mustang Advanced Engineering (MAE) announced it delivered a heavy-duty transmission dynamometer for testing of large truck transmissions for Edelbrock at its Cerritos, California, R&D facility. The state-of-the-art test cell was designed by MAE to efficiently accommodate the need to test repaired and refurbished transmissions by way of CAN communication, while meeting all required codes for mechanical and electrical hookups as established by state and local regulations, the company says.

The difference in this transmission dynamometer is the use of CAN communication, MAE says. “Controller Area Network” or “CAN” is an electronic communication bus, developed in Germany in 1986 and defined by the ISO 11898 standards. Those standards define how communication happens within the transmission, signaling when and how the transmission shifts. Collectively, this system is referred to as a CAN bus.

MAE says the system can perform a multitude of tests via CAN, including:

  • Check shift points (automatic transmissions)
  • Full throttle upshift test
  • Downshift inhibitor test
  • Check for abnormal noise and vibration
  • Check transmission control system
  • Closed throttle downshift test
  • Leak check shaft seals and clutches
  • Check main, clutch, and converter pressures
  • Determine mechanical binding

“As a global leader in the design, manufacturing, and integration of transmission dynamometers, MAE’s advancement with CAN communication systems is available for testing all the world’s largest OEM transmissions. MAE has delivered and continues to support transmission testing systems in virtually every corner of the globe.” said David Ganzhorn, vice president, sales.
