If I remember right, my brother has a 7speed. Believe it is just a straight H pattern, with no splitter.

 

So it would be a straight 7 with a set of granny's?

 

If its in a Mack i woud say thats the common sense answer. If it something else I couldnt see swapping a mack 7 spd into it but stranger things have happened l guess.

 

Guess ive never driven one.. how is it a 7 if it has a split?

 

Looking online it looks like reverse, 1st and 2nd have a deep reduction available. Kind of like shifting a 15 spd or 8LL. I think i drove one years ago once or twice. I remember big gaps between each gear. Probably what gave R models that distinctive sound and the puff of smoke going through the gears.

 

The low gear is split for lower gears, I think there are two splits for low gear with the 7LL. I had one with a single split on low gear - 7L.
