I remember how it was before GM brought the Allison to their 2500/3500 trucks.
It was common to need a tranny rebuild before 100K... Many reports of around 70K. GM upped the standard, and enjoyed the tranny crown for a few years. That forced the others to step up. Of course being first has advantages. The Allison became the standard against which all of the others were judged.... That really grates on some of the OB fanboys.... What they are not giving credit is to the fact that if not for GM.... They would likely still be stuck with those old unreliable trannys. Enjoy your new trannys, and give the bashing a rest
