I have a newholland t6030... Show More
I have a newholland t6030 tractor with 16x16 trans. It starts jerking when taking off once warm and will eventually kick out of gear and will not move until key is cycled. No error codes show up when this happens. I have the calibration procedure, but usually about half way through, the screen that shows what clutch pack is being calibrated just goes blank.

1. Does the yellow ! show up?

or anything in the hours display?

Customer reply replied 1 year ago.
No, the display in the center that shows which clutch is being calibrated just goes blank. It seem to be either c2 or c4 that is being calibrated when display goes blank.

Does anything show up at the bottom (pto spped) display?

the only thing else I can come up with is.

Clutch drag when using the inching pedal.
Insufficient clutch pedal travel.
Manual calibration of the transmission clutches.

  • 16x16 ,17x16 transmission module DS software level 02.06.00.00. or higher.

Clutch calibration and quick fill manual adjustments

Heat up the transmission oil to 60 degrees Celsius (108 degrees Fahrenheit).

The test has to be performed with the range lever in high range with the highest possible inching gear for the relative clutch (The clutch is selected based on the normal gear selection and on the channel number that you have selected).

Select DB/DF/DS/DT- H7

  • Channel 4 is used to adjust C1 and C2
  • Channel 5 is used to adjust C3 and C4
  • Channel 6 is used to adjust C5 (17th, if fitted)

Procedure:

{C}1. Ensure that the tractor is parked on hard level ground, the range lever is in the high range position, and that the transmission oil temperature is above 60 degrees Celsius (108 degrees Fahrenheit).

{C}2. To adjust and test the C1 and C3 values, select 12th gear, fully depress the clutch pedal and move the shuttle lever into the forward position. The clutch calibration value for C1 or C3 will be displayed (in the relative channels).

{C}3. The range switch is used to switch the display between the clutch calibration value and the clutch quick fill time.

{C}4. To adjust the clutch calibration value first ensure that the display is showing the calibration value. When the display is currently showing the quick fill time then use the range switch to change back to the calibration value.
Fully depress the clutch pedal and use the upshift and downshift switches to adjust the calibration value either up or down.

{C}5. To test the calibration value, slowly completely release the clutch pedal, then depress it slightly and release it. The correct value has been achieved if the tractor starts to creep.

{C}6. To adjust the clutch quick fill value first ensure that the display is showing the quick fill value. When the display is currently showing the calibration value then use the range switch to change to the quick fill value.
Fully depress the clutch pedal and use the upshift and downshift switches to adjust the quick fill value either up or down.
Values in the range 3 to 19 may be selected.

{C}7. To test the quick fill value completely release the clutch pedal, then depress it slightly and release it. For a proper adjustment the transmission oil has to be over 85 degrees Celsius (185 degrees Fahrenheit). For a good setting no perceivable kick is to be felt, just the creep due to the calibration value.

{C}8. To adjust and test the C2 and C4 values, put the transmission into neutral, and repeat step 2, but select 13th gear (in the relative channels).

{C}9. Once all of the clutches have been manually calibrated key off.

{C}10. Remove the diagnostic connector and restart the tractor, check that the bite point of the vehicle is the same when using the C3 and C4 clutches. This can be achieved by having the tractor at the bite point in 7th gear and then shifting to 8th. When the vehicle remains at the bite point then no further tuning is required. When there is a loss of drive of the vehicle starts to move then further tuning may be required.

DB/DF/DS/DT -H3-Channel 1 - manual Quick Fill Adjustment

This channel is used to adjust the transmissions quick fill setting. A flat concrete or asphalt area should be chosen to perform a correct manual adjustment .
Set engine rpm to 1200 rpm.
Warm the driveline oil to at least 60 degrees Celsius (108 degrees Fahrenheit). When the oil is too cold the display will alternate between Cold and the oil temperature in degrees.
Quick fill adjustment is not possible until the oil warms up. When a four-digit number beginning with 2 is displayed at any time during the calibration procedure, it is a standard error code. The fault condition must be corrected before calibration can be performed.
To select C1 or C2, shift the range lever and shuttle lever to neutral, then use the up shift or downshift switch to select C1 or C2. The selected clutch and its quick fill setting will be displayed. To adjust and / or test the quick fill setting for C1 or C2, shift the shuttle lever to forward and release the clutch pedal. The display will change to C while pressure is ramped up in C3 and C4 to stop rotation of the transmission gears in preparation for testing C1 or C2. The lower central display will change to display the clutch and the current quick fill setting, e.g. C1 4.
The quick fill setting can be adjusted within the range of 3 to 19 (30 to 190 ms) by using the upshift and downshift switches.
To test the quick fill setting, engage the clutch by slightly depressing and releasing the clutch pedal. Do not push the pedal all the way down.
C3 and C4 will turn off while C1 or C2 is engaged for about one second. The display will change to C again briefly while the pressure ramps up again in C3 and C4. Reduce the quick fill setting, if necessary, until there is no 'clunk' noise when C1 or C2 engages.
Increase the quick fill setting until there is a distinct clunk.
Then reduce the setting by two.
To select C3 or C4, shift the range lever to high and the shuttle lever to neutral, then use the up shift or downshift switch to select C3 or C4. The selected clutch and its quick fill setting will be displayed. To adjust and / or test the quick fill setting for C3 or C4, shift the shuttle lever to forward and release the clutch pedal. The display will change to C while pressure is ramped up in C2 to drive the input side of C3 and C4.
Ensure the park brake is released.
Ensure the area around the tractor is clear, as the tractor will move when testing these clutches.
The lower central display will change to display the clutch and the current quick fill setting, e.g. C3 4. The quick fill setting can be adjusted within the range of 3 to 19 (30 to 190 ms) by using the up shift and downshift switches.
To test the quick fill setting, shift the shuttle lever to forward.
Engage the clutch by slightly depressing and releasing the clutch pedal.
Do not push the pedal all the way down. C3 and C4 will turn on for the quick fill time plus 0.1 seconds. The display may change to C again briefly.

Reduce the quick fill setting if necessary until there is no tractor movement when C3 or C4 engages.
Then increase the quick fill setting until there is a noticeable tractor movement.
Then reduce the setting by two.
The revised quick fill settings must be saved by pressing the h or m button till a audible tone is heard.�

Test the quick fill setting by slowly releasing the clutch pedal, or by starting up or shuttle shifting without using the clutch pedal. Too much quick fill will cause an initial jerk. Too little quick fill will cause slow response. Power shifts can also be tested, though this is probably the poorest way to tune the quick fill times.
