When rebuilding an automatic transmission or replacing a valve body, one of the most difficult tasks for the technician is being able to accurately test every component of the transmission and valve body for proper operation before returning the unit to service. The tools most commonly used today aren’t able to truly test the system under conditions similar to what it will experience once out on the road, leading to a semi-steady comeback rate.

SuperFlow is a market leader in the area of dynamometers and flowbenches; you may have even seen our in-house SF-750 flowbench in previous articles. In an effort to assist the industry, the team at SuperFlow has released the video above introducing their WinDyn CAN Control system, adding the ability to control and shift mechatronic valve bodies and solenoids on transmission dyno’s and valve body testers.

The WinDyn CAN Control system differentiates itself from the competition by having the ability to accurately simulate the vehicle’s controller area network (CAN-Bus), as if it were communicating directly with the vehicle on a normal drive. Having this CAN simulation allows the transmission control unit (TCU) to make real time decisions and adjust shift points based on the throttle position and torque input set by the operator.

This advanced system even allows the operator to clear DTC codes to eliminate limp mode, and is guaranteed to thoroughly test the system and greatly reduce customer comebacks.

The SuperFlow WinDyn CAN Control system is currently compatible with some of the most popular transmissions, such as Nissan’s RE5R05A, GM’s 6L50/80/90, and GM’s 6T40/45/70/75.
