Its not that hard, belive it or not. You can drive it like an 8-speed if you really want, then adapt to splitting the uppers as needed.

If you drive a stick bug, think of it like this-

1,2,3 are normal, but lets say you have a 4, 4.5, 5, and 5.5 as well.

So, lets say you are in 5th, and don't necessarily want/need 4th- well, you can go into 4.5 (in between 4 and 5) or you can still go into 4th if you desire. Its literally the flip of a button, and looks a LOT more intimidating than it seems.

Do you always "have to" use low/high or just in the hills or different driving conditions- I live in the hills?? Or if you are going down freeway just stay on one side? huh will I confuse myself more by asking that? well see ahaha

You can use it at any time but it would really be useful in the hills. But for most driving you can probably skip splitting each gear until you get to 8th, then split to 8th high when cruising.

For example: Eaton discourages extended cruising in 8th low because that position sends the power through two sets of gears (0.73 overdrive in the main box and a 1.17 underdrive splitter gear) and having the transmission run through both gear sets can generate excessive heat.

The bottom line with this or any other type of transmission is that at any given road speed you must use the proper gear to keep your engine RPM's in the proper operating range.

Its not a hard as it looks, its harder to explain though...lol

Thanks so much, for your time. Kelly and arm.
