14 speed transmission?

First time driving an autoshift in 49 years of trucking. Gotten used to how to work with it. What I cannot figure out is how it has 14 gears. 1-13 plus a low. I've never encountered such a thing. How would you get 14 gears if it was manual? Maybe a 13 plus an air selected low range? This is a new one on me.

 

Nope. It's got 14 forward and 2 back.

 

You don't usually count reverse. EG 18 speed=18 fwd gears, 13 speed = 13 fwd and so on. This thing has 14 fwd. Just thought I'd see if anybody was familiar with this trans.

 

This one has L, plus 1-5, then it does a range shift goes to 6, and sounds like it splits the top end, like a 13.

 

Yes, I used to use that gear sometimes going around a corner, saved going into low range. Just had a bigger rpm split than going down to low range. Anyway, regarding this 14 speed transmission, I've given up finding info on it. The truck was built in Mexico but can't find a model # of the trans. But it's definitely got 13 speeds, plus a low gear. I'm just going to drive it and not analyze it further. I will say, the autoshift is nice in the city but I sure wouldn't want to take it off road, back into the bush and icy hills. Even an old Mack with a 6 speed would be better there. Thanks to all who replied. I'm done on this one.
