brutus998 Posted March 26, 2008 Share Posted March 26, 2008 Wouldnt this be an awesome combo? I have heard from a very reliable source that Mack manufactured E9's with an Allison-Autos. I heard these trucks were used in airports. Anyone else heard of this? Quote Link to comment Share on other sites More sharing options...

Anyone else heard of this?[/quoteI have seen off road log trucks with the big allison nothing else !They even had problems getting that to stand up behind E9 the torque and rpm range was way to low They finally got it to work thou and it was just fine power wise As the big tranys go into lock up as well as have a manual lock up ,the beauty with the big allison is the built in retarder which helped the E9 loads because of the poor engine brake quallitys Quote Link to comment Share on other sites More sharing options...
