I had a problem similar to your's. MH 1997 Engine:Cummins M-11. trans. Allison HD4060R. Allison dealer shop said NO fault code, go see Cummins/Freightliner dealer. Result: lots of false code on engine ECM (electronic control module). ECM shot need new one. Put new one in ($3800.00) all problems solved. Rene
