Allow sufficient time for the corresponding clutch to be fully pressurized.The software program that will be used for this test procedure is the Caterpillar Electronic Technician (ET). The Caterpillar Electronic Technician is a software program that can be used on an IBM-compatible personal computer.Reference: For more information about the use of Electronic Technician, refer to Testing and Adjusting, "Using Caterpillar Electronic Technician (ET) to Determine Diagnostic Codes" for the machine that is being serviced.
Open the software program (ET). Select the "Transmission 834G" or "Transmission 836G" menu item.
Select the "Service" menu in order to begin the calibration procedure. Then select "Calibrations". A second menu will be displayed. Select "Transmission Fill Calibration" from the second menu.
The next screen is the initial calibration screen. Once "Transmission Fill Calibration" has been selected, the screen displays the incremental instructions for calibration. The top display area displays status parameters that are monitored during the calibration. The middle display area displays information about the status of the calibration. The bottom display area displays incremental instructions for the calibration. The step that currently needs to be carried out is in bold text. All other steps are displayed in gray text.
Press the "Next>" button in order to start the calibration. The "Next>" button is disabled, until the current step has been successfully completed. A check will be placed in the box that is left of the step, after the current step is complete.
