65275 Retarder Fluids: RF Broadcast Driveline Retarder The SAE J1939 data link provides a method by which the transmission can limit speed/torque of engine or do a speed override of the engine.Using the SAE J1939 data link, the transmission can send TSC1 messages to the engine to limit the torque output of the engine during a shift. This may be needed for protecting the transmission mechanical parts or it could be used just to improve the shift quality. There are two different needs for torque/speed limiting. One is during the shifts, the second type of torque limiting is needed by the transmission when the transmission is at stall condition. The engine speed will be limited to keep too high of a torque from being transmitted through the transmission.
