*****************
relating to the gearbox which is what I believe he is discussing here,
EVERY gearbox, except one with an overdrive ratio has a direct 1 to 1 ratio
in fourth gear. There are really only three gear sets in a four speed
gearbox. In fact the power is transmitted directly to the output shaft
by-passing the countershaft and other gears altogether so this statement
concerning the transmissions fourth gear ratio is entirely correct, that
is, "fourth" gear is really not a gear at all but for all intents and
purposes a direct connection to the engine itself. However, the rear end
or differential (final drive) ratio can be changed and this will certainly
change the spedo reading but will not affect the gear ratio of the
transmission itself - only the combined ratios of the tranny and rear drive
together -
