Section 6, Automatic Transmission
Learning
The 6.6L Chevy Duramax Trucks
equipped with the Allison 1000
5-speed automatic overdrive
transmission use an adaptive shift
control logic. This will require the
transmission to adapt to the additional
power created by the Banks Power
products before it will shift properly.
Failure to follow the sequence can
result in damage to the transmission.
Perform the following sequence
at a location where it is safe to
accelerate without exceeding the
posted speed limit.
1. Set Six-Gun to level one power
setting, start the truck and allow the
engine to reach normal operating
temperature.
2. Adjust Six-Gun to level two, power
setting.
3. Drive vehicle for 5 to 10 miles
ensuring a complete shift cycle though
each gear. (The transmission shift
adaptation learning process requires
15 to 30 complete shift cycles to learn
new shift program.)
4. Increase power level by one and
repeat Step 3 until the desired power
level is achieved.
WARNING: Take particular care not
to do wide open runs in 5th gear
when in Automatic transmission
Learning Mode, especially if speed
loader is installed.
The Allison 1000 5-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.
