So to sum up what I've been seeing regarding transmissions, the VH-9 was a two speed transmission and was used on the old new-looks. (this is why the acceleration noise seemed to peak at a much slower speed than others). Newer fishbowls and Flxibles and everything afterwards used v-730, which was 3 speed (one person said four), and this was like a cross between the older transmission and turbocharging.
Is this correct?
A couple of other question: were VH-9's ever used with 6V-92? (Is this what the Peabody garbage trucks use? The older ones sound kind of like the old fishdowl engines, but accelerate like turbocharge (6V92). The next batch sound alot like the Orions, and of course, the newest ones. like everything else, have gone with some sort of 4 cylinder (probably the same series 50). Are the new series 50 buses V-730 also? Were the MC-9 transmissions V-730 as well?
