Yes it's a 5 speed. Anyone know when that new 6speed Allison 1xxx is going to be released?
In a related issue, I never understood the so called Ally "excess shifting" criticism from the other diesel camps. The Ally 1000 has an extra gear to be used, so it has more flexibility than a 4 speed auto and so it keeps the RPMs in the power band better. From a fuel efficiency perspective isn't that exactly what you want a 5 or 6 speed auto tranny to do?
