have a Winnebago 2009 adventure with Ford V10 and 5 speed torque-shift trans, tow/haul mode. the transmission does not want to shift down when pushing or tapping the accelerator pedal. this happens often. only 15000 miles. been doing it since purchase new. also when driving down road has a wine that loud in the cab. if you back of the accelerator it will stop, if you re-apply pressure starts back. fluids good, not the tires.
thoughts....need advise. we are full timers.
