Case Wheel Loader 721E EU Service Workshop Manual
SAMPLE PAGE OF THE MANUAL:
- General The transmission is equipped with a Transmission ECM (Electronic Control Module). This module controls modulation and shifting that were normally associated with hydraulically modulated transmissions, providing smoother shifts and enhanced clutch life. The Transmission ECM relies on signals from several sensors that are incorporated into the design. These sensors measure the speed of several components, as well as other sensors that measure temperature.
- These solenoids and sensors are further defined in the following paragraphs. In addition, the transmission incorporates a two-piece transmission case for ease of transmission maintenance, helical cut gears that help reduce noise, and all external hoses have been eliminated (all oil passages are internal). Transmission ECM Modulation and shifting are controlled by the Transmission Electronic Control Module (Transmission ECM). This module replaces the oil and springs that are found in hydraulically modulated transmissions.
- The Transmission ECM controls the clutch engagement, providing smoother shifts and enhanced clutch life, whether the transmission is set to the automatic or manual shift mode. The Transmission ECM also informs the Information Center, by the use of diagnostic codes, of any transmission error and the hours of operation that the error occurred.
- Electrical Shift Solenoids Electrical Shift Solenoids control the modulation of the clutches, eliminating the need for a modulation valve, and providing a smooth shift while maintaining constant control over clutch engagement as follows: A. A temperature sensor relays the oil temperature to the Transmission ECM. B. The Transmission ECM times the rate the solenoid energizes and de-energizes. C. As the transmission changes gears, there is reduced hesitation from one gear to the next.
- Transmission ECM Tasks The Transmission ECM performs a variety of tasks in the overall system. The Transmission ECM:
- Determines which clutches to engage in the transmission Protects the engine and transmission turbine from overspeed condi t i o ns dur i ng downloading. Receives speed information from the engine speed sensor, the turbine speed sensor, the intermediate shaft speed sensor and the transmission output shaft speed sensor. These speed sensors are checked to determine if normal sensor operation is present. The data is also used to control modulation during shifting and to determine the appropriate shift patterns.
- Detects system failures and determines the appropriate alternative actions. Provides various diagnostic messages to the Information Center. Provides other information to the information center, which in turn displays engine speed, wheel speed, gear shift selection, and actual gear selection. Provides a method to calibrate the transmission clutch control. H. Establishes clutch modulation pressure during transmission shifts.
