Re: allison shifting erraticlly
I agree with C. Nash. An RV is not a car. You can't put them in cruise and get the same behavior. The powertrain and weight of these vehicles is more like a truck in that they are limited in their performance as compared to a car. As an RV climbs a hill, it will slow down. When it hits a downshift point, the trans will downshift. You then make more torque and speed up. The transmission upshifts, etc. etc.
