to do wide open runs in 5th gear
when in Automatic transmission
Learning Mode, especially if speed
loader is installed.
The Allison 1000 6-speed automatic
transmission will continually adapt
to the power output of the engine to
optimize shift quality. The transmission
will quickly adapt to the power setting
if the driving cycle includes regular
gear changes at high loads. The
transmission learning procedure will
need to be repeated when switching
back to the higher power settings
once the transmission adapts to
the lower power settings. It will be
apparent when the transmission
adapts to the lower settings by
monitoring the feel of the gearshift.
Gear changes will be noticeably harder
when initially switching from a higher
to lower power setting. This will soften
as the transmission adapts to the new
setting.

The Six-Gun Diesel Tuner requires the
engine coolant temperature (EcT) to be
above 110º before it will add fuel. If the
optional Banks PowerPDA or DynaFact ®
gauges are installed, observe the
operation of the boost and pyrometer
(EGT) gauge values while driving under
varying conditions. Turbocharger boost
pressure will increase as a function of
load and engine RPM, thus the engine
will produce little boost while cruising
at light throttle, with maximum boost
while climbing hills heavily loaded during
acceleration. Note the boost level seen
during hard acceleration with a given
load. If performance seems to have
deteriorated sometime in the future,
the maximum boost figures may be
compared to see if boost has dropped
off. Lower boost may be caused by
turbo ducting leaks, a malfunctioning
wastegate or fuel injection pump, or
dirty air filter. Typical maximum boost
pressure settings will vary considerably
with stick or automatic transmission
options, year model of vehicle and
altitude.
Note: Before key-off, check tuner for
error codes. Use your Banks PowerPDA
or eGt gauge to monitor exhaust gas
temperature (eGt) in the engine. At
idle, exhaust gas temperature will be
very low, perhaps only 300°F. As the
engine is accelerated for higher speeds
with greater loads, the eGt will rise.
the highest eGt will be seen under
maximum load at full throttle, such as
climbing a steep grade with a heavily
laden vehicle. to avoid heat damage
to various engine components it is
recommended that the exhaust gases
cool below 400º before the engine is
shut down. Your Six-Gun Diesel tuner
is calibrated to maintain a maximum
eGt of 1350°F. You may experience
brief excursions slightly above 1350°F
under acceleration. this is normal and
eGt should return to 1350°F or below
within a few seconds. If you find that
eGt remains high for any length of time,
check for boost leaks or a dirty air filter.
