It's random and when I drove it from the Freightliner to Allison shop the other day, I was able to duplicate it several times and the engine brake was off.
First time it ever happened I thought maybe it was not warmed up enough.
Recently happened coming out of a rest stop on I-20 and would not come out of 2nd. Not a good situation with on coming traffic at 70+ MPH.
