Strange Fact: if you do the math on the gear ratios, we don't actually have overdrive. our 5th gear (6th for the sx and new ones) **still comes out to like 2.8:1 ish after factoring in final** drive. And yet we still get 30mpg. Very Efficient Engine.

Also explains why I can still accelerate pretty decently in 5th gear at about 55mph.

In 6th speed the final ratio is 2.227:1** (6th spd 0.772 X final drive 2.885)

The 5 spd is

**SLIGHTLY*** better for MPG at 2.209:1 (5th spd 0.713 X final drive 3.099)...and in the 5spd tranny there is no 1:1 spd -- both 4th and 5th are actually overdrive ratios (less than 1.0)

Ironically, even with the extra gear, the 6spd is at a

**SLIGHT*** disadvantage over the 5 spd off-the-line:

5 spd 1st gear final drive ratio: 12.207:1 (1st spd 3.939 X final drive 3.099)

6 spd 1st gear final drive ratio: 12.151:1** (1st spd 4.212 X final drive 2.885)

However, the 6 spd has better numerical 2nd and 3rd speeds for better acceleration.

..and if you don't understand what ratios are...think of a ten speed bike. It is easier to start off in 1st and not 10th. The ratio is much higher in 1st just like the 1st speed of a tranny. ...and to be technical there isnt a 1st gear, 2nd gear, 3rd gear, etc. in our trannys...it uses three planetary gear sets to make the different speed ratios (most auto trannys only have 2 planetary gear sets -- BUT some Honda auto trannys DO have gears...LoL!). It would take too much time to write up how these work...if you want to know more look up auto trannys and planetary gear sets...LoL!

***Almost negligible because the difference is VERY SMALL**
**...and for those that STILL don't get it:

with the 6 speed tranny in first gear the engine spins 12.151 times for each revolution of the wheel...in 6th speed the engine spins 2.227 times for each revolution of the wheel. in 6th speed when the wheel is spinning at 1000 RPMs the engine is at 2227 RPMs.
