Increase engine RPM above 1500. This will unlock
the clutch. Failure to do this will set a clutch disen-
gagement code and the code and transmission will

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.

tionary, and the engine not running.

vated.

tional upshift (UltraShift gear display will display a
“1” with up arrows indicating UltraShift Touch Point
Resent is selected.)
