MD Ultrashift Clutch Recalibration
1. Turn key on.
2. Verify a solid "N" is on the gear display.
3. Start engine.
4. Increase engine RPM above 1500. This will unlock the clutch. Failure to do this will set a clutch disengagement code
and the code and transmission will not go into gear.
Note: Programmable VSS Tamper Resistance options or other artificial engine speed limits which prevent reaching the required
1500 RPM may prevent proper disengagement of the clutch locking device after initial installation. These options may
need to be disabled until after the clutch-locking device is disengaged.
Note: If ServiceRanger is available, proceed to Step 12.
5. Start with the system powered down, the vehicle stationary, and the engine not running.
6. Key on and allow the system to completely power up but do not start the engine.
7. Select "LOW" mode on the shift controller (UltraShift system will begin to emit an audible tone).
8. Select an upshift once (UltraShift gear display will display a "0" with down arrows and discontinue the tone indicating
"Special Functions" mode is activated.
9. Once in Special Functions mode, select one additional upshift (UltraShift gear display will display a "1" with up arrows
indicating UltraShift Touch Point Resent is selected.)
10. After the "1" is displayed, depress the throttle pedal to the floor and hold for 3-5 seconds (the gear display will change
back to a "0" with down arrows indicating the routine has been successfully completed.
11. Key off or select any mode and the UltraShift system returns to normal operation.
12. Save clutch data / Recalibrate clutch with ServiceRanger.

really depends on generation. New Ultra Shift must be calibrated like I-shift with computer - stroke and grip point. ZF autocalibrates every time you turn engine on

Tonight I had a new driver "abuse" my Ishift, I am hoping no lasting damage, but I definately think my clutch life has been shortened substantially.

Basically, he got stuck pulling out on an approach in some snow, and attempted to rock himself free, finally giving up and calling me to come into town and tow him with my half ton.

I arrived, hooked on, and it wouldn't budge, turns out it wouldn't even go into gear, so I jumped in, turned truck off, let it sit for a minute, immediatly noticed a smell of burning clutch, started it back up and it would go into gear.

I questioned my driver as to wtf happened, he said "clutch overheat protection" come up on the DID.

So has anyone else had that happen? What is the normal lifespan of a Ishift clutch? I hope having the D16 heavy duty ishift that it shut it down before any major damage.

We got it out, and it shifts fine now, smell is gone, things have cooled off, my only concern is lifespan. I can only imagine the clutches aren't cheap... thankfully he was empty, not loaded.

Thanks for any input!

Just to be on the safe side I would spend one hundred dollars in a Volvo shop for an oil sample of the gear box. Consider it, insurance. the oil sample can't go above the 30 dollars but the labor at the truck dealers it is what it is.If they are spitting on your door, they will give you a bill for truck wash.
