    Curious is any of you have any experience with these. I am looking at a used truck, but it has an auto trans and I do not know anything about them. Thanks

    I think most gov. trucks (buses & dumps) are auto trans. so they must be built pretty well. Any local county maintenance dept. could probably let you know about reliability.

    if you could clarify which size topkick youo are asking about would be helpful. it will also depend on what engine is pushing it. such as a gas engine and automatic in a mountain area might not be a good combo even though the transmission is a good one.
    good luck,

    It doesn't matter what brand of automatic transmission it is they cost money when they break. If its a 3-5 ton truck it would have a Allison transmission I would be checking when the last service was done to it. How many miles are on it.

    If you are going to have a automatic 5 ton truck is if its on air brakes because if its on juice brakes and your depending on a driveshaft emergency brake to hold the truck forget it. The big automatics don't have a park only neutral so there is nothing to stop it from rolling away with the engine shut off except for the emergency brake. You tow a trailer and your parked on a slight hill with a loaded trailer you will have a runaway.

    So its a 4500 or 5500 series truck. It might have the AT545 4 speed trans in it depending on year. If its newer, it might have the Allison 2000 series in it (I think..)

    The big block 496 Chevy isn't all that bad probably a little hungry for fuel but otherwise a decent engine. Not sure what transmission they would have used I'am not a chevy freak :laugh:

    If the 496 then it should have an Ali.
