    Sorry but a 13 speed is a 13 forward and a reverse, Right below the reverse gear is the 1st forward gear, Then the standard h pattern, making 5 forward gears in the low range, In high range you can split each 4 gears, making it 8, 8 + 5 = 13

    Yeppers, and there is even the secret gears you're not supposed to use adding two more.

    And to further this, if the OP ever gets into an 18 speed, It is the same as a 13, but you can split the low side as well as the high side, 5 gears split on the low side making it 10, 4 gears split on the high side making it 8, 10+8=18, If you can drive a 9 speed, you should have no problem getting use to a 13 or a 18 pretty quickly, Only thing, the split does work on the reverse gear on a 18 speed, but don't use it to split to the high side, not good for tranny, only use low side reverse

    I'm jealous too... 13 spd is the sweetest truck tranny. Great for control in mountains.

    Crzyjarmans.....I stand corrected. you're correct. I guess since no one really uses 1st (compound low) I didn't actually count that gear. I'll add, I never used that gear. And yeah, there's 2 secret gears. I seem to remember just 1.

    drive it as a nine speed, unless your pulling a lot of weight. its not as hard as your thinking it is, you will be alright.

    Use the splinter on heavy loads when trying to get to top speed.
    On the way down, I often drop 1.5 gears at a time.

    It is pointless to drop a half gear if you know you will drop more gears right away.

    When you run 3.36 and 24.5 you use it more than you want to, or at least I do. The secret gear can be split, which makes two, correct?
