They all seem to have a very long 2nd gear. Then this low pitch rising humming or roar starts up. The motor rpm's stay the same - like it's stuck, but that other sound keeps going up toward the rpm's. Then, it feels like a stick shift(hard forward boost or jerks) when it finally goes into 3rd gear & and that sound becomes higher than the motors rpm's. This is where the bus feels like it is really pulling. The bus engages 4th gear like a typical automatic. Call me wierd, but its almost like music to me(I'm not the only one facinated with the sound of motors) Why?

The humming sound you hear is coming from the differential on the back axle. It is from the gear lash within the unit.
