Transmission Clutch Calibration
The Transmission ECM has the capability to find the optimal adjustment of the clutch filling parameters for each individual transmission, providing the ability to individually adjust the optimum fill time for the individual transmission in the machine. Clutch Filling Parameter Calibration is performed on each machine at the plant and should be repeated at the first 250 hours of use and every 1000 hours thereafter.
Before doing the following transmission clutch calibration procedures make sure of the following:
1. The machine is running and the transmission oil is warm.
2. Engine low idle speed is correct.
3. The transmission is in neutral.
4. The park brake is applied.
5. If steps 1 through 4 have been accomplished, calibrate the transmission clutches as follows:
A. Press and hold the enter key for 2 to 3 seconds and the monitor will change to SELECT.
B. Use the down arrow and high light “CONFIG”, press the enter key.
C. Press the down arrow and high light “CALIB G/B”, press the enter key.
D. Monitor will state “CALIB G/B” “CONFIRM PLEASE”, press the enter key.
E. If the conditions are not correct for clutch calibration the monitor will display the problem that needs to be corrected.
F. Clutch calibration status will be displayed on the monitor, “ADJUST K1, K2, K3, K4, KV, KR”.
G.After completing the Clutch Calibration procedure, turn the machine OFF for 15 seconds. This sets the calibration in the controller.
Gear Selections
The transmission provides 4 forward and 3 reverse gear selections. The transmission ratios were designed to give optimized speed and torque for each gear selection. The torque converter is a single stage torque converter (one locking unit in the torque converter).
Automatic/Manual Modes
The automatic/manual switch is located on the right control panel. The transmission is in automatic mode when the top of the automatic/manual switch is depressed. The Transmission Display Center indicates when the machine is in the automatic mode.
Upshifting in Automatic Mode
Upshifting is determined by machine speed and the torque on the transmission.
The transmission will shift from first or second gear up to the highest gear selected as the accelerator is depressed, machine speed increases, and required torque is reduced.
If the machine speed is increasing, but the operator
is not depressing the accelerator (such as when going down a hill), the transmission will not upshift.
As the operator depresses the accelerator and the torque on the transmission is lowered, the transmission will upshift.
Downshifting in Automatic Mode
Downshifting is determined directly by machine speed and transmission torque. The transmission will downshift to first or second gear as machine speed decreases and transmission torque increases. For example, if the unit begins to climb a hill in forth gear and the machine speed decreases, as the torque requirement increases, the transmission will downshift into third, then second, and down to first gear, if necessary.
Upshifting in Manual Mode
In the manual mode, the transmission starts out in the selected gear and stays in that gear until the operator selects another gear or direction. The transmission can be upshifted without reducing engine speed or machine speed.
If the gear selected is two or more gears higher than the present gear, the transmission will shift up through the gears at 2.5 second intervals until the selected gear has been reached.
