Driveing in overdrive?
My Class C has a E4OD transmission and I live in FL where it's flat, so my question is, should I drive all the time with overdrive turned on? It does seem to shift better when I do.

Transmissions like ours do not have five speeds. They're basically the venerable (and legendarily tough) C-6 three speed with an overdrive gear, and then an electronically controlled valve body, added. All our "OD Off" button does is limit the transmission to three speeds with converter lockup. The newer 5R110 (popularly known as TorqShift) has more gear ratios available. It picks among them and doesn't use all at once. It OD ratio is same as ours. The big difference is the Button is now "Tow/Haul" and it re-programs the transmission. OD is still possible, but lots of things happen behind the scenes. It also downshifts when you brake, to help control speed on downgrades.
