Okay, I may sound stupid here, but I thought a 4 speed w/overdrive meant 3 gears, and an overdrive gear as the 4th, right?
When I drive, I'll count 1-2, 2-3, 3-4... then another shift? My RPMS drop another time.
Do we have locking torque converters that would cause it to stop slipping and drop my RPMs another ~1000 RPM?
A friend mentioned something about some auto transmissions having "high and low gears", which, frankly, I'm not buying.
