What do they actually rate the holding capacity of the Trans-go ?? I've seen Steve Cole state over 500/900 ,is that flywheel or RW numbers ?? Different # with a Triple Lock,or same ?? What do you offer as a guarantee number ?? I wouldn't go with out a triple lock but that's me ....Mike L. said:The Allison will handle a lot of power with a shift kit and heavy duty converter. Anything above 90hp can and usually will throw a code and limp the trans. Happens in the upper gears when you play.
