    only people that used that are class 7 and below and the Military. The reason it it won't hold up pulling 80,000 lb doing 70 mph for1,000,000 miles.... case in point the military use 6 speed Allison, can't go faster than 60 mph (would blow the engine) need to be replaced abfor 200,000 miles

    And per Allison they at this time just started making the TC10 for class 8 (not available yet) and it's for SHORT haul only... so NO you can't even order a Allison for a class 8 otr truck..
    Allison CEO talks automatic transmissions, expansion into class 8 market

    The article is only 5 years old. I agree its not for Heavy applications.

    All that asside.......there are tons of class 8 trucks rolling with Allison 4500. MX power and the 4500 is a awesome combo IMO and puts an Ultrashit plus to shame.

    Spelling pun intended.

    I do work on a fleet of 12 gravel hauling 2012 KW T660 that have Allison 4500 in them. Pretty bulletproof except for wiring issues.(Michigan salt/snow)

    the reason is because the 2 transmissions (automated v automatic) have nothing in common. How they work and the internal parts are completely different.

    If you have the same problem with both the fix WILL NOT be the same..
