Allison 6 speed w/lock out
Looking at an Allegro Breeze, and it advertises an Allison xmisson with lock out. What series Allison is this(1000..2000?). And what is lockout?
Forum Discussion
Got this response from the retired Allison engineer.

The transmission goes into lockup in all forward ranges. Lockup is based on the speed ratio between Input Speed (Engine and TC Pump Speed) and Output Speed (TC Turbine Speed). The transmission will automatically be in "Converter Mode" until the speed ratio is small enough to actuate this Lock Up clutch inside the Torque Converter. The transmission gives you variable torque multiplication in Converter Mode, through the Stator, and 1:1 in Lock Up Mode.
Does that help ??
