    It appears that on every truck with an automatic transmission the engine brakes are a joke.

    Well finally got an answer to what the problem is. Company spec’d the trucks with only 2 stages (Low & Med), So now fighting with the desk jockeys to get new programming.

    Reset the software to Factory, but still same issue. Tech from Detroit factory looked at it and is stumped as well. The saga continues

    I'm in an paccar equipped auto trans Kenworth. I've driven Peterbilts equipped the same. Their engIne brakes suck compared to a Jake brake equipped Kenworth i drove with a stick in 2008.
