2006 6-spd transmission ratios and max speed

[nbtx]

Here are speed calculations for my 2006 MT. The gear ratios
are from the 2006 TSX sales literature. Note that the published
ratios are to only three significant figures so accuracy
could be improved by counting gear teeth. But since my tire
measurement is also to three significant figures the calculations
are pretty close. Also note that the speeds are actual, not
indicated - your speedometer and tachometer are not that accurate.
I've separated the three columns with semi-colons because the forum
absorbs spaces and tabs.

gear;gear ratio;speed in mph at 7100 rpm with a 78.1" circumference tire

3;1.36;81.1
4;1.03;107
5;0.83;133
