Only reason anyone would think that is they have never driven a 13spd B model.
You are correct only 2 I ever jockied one had a 9 speed and the other a 15. What am I doing wrongOnly reason anyone would think that is they have never driven a 13spd B model.
I didn't mean you Tyler, The 13B is/was not a common model.You are correct only 2 I ever jockied one had a 9 speed and the other a 15. What am I doing wrong
Yes that gives more time to eat Little Debbie Snacks.I learned to drive on a Mack DM with a 5+1 and 300hp
Ah I thought I was going to learn a new thing. I'm sure I don't shift them properly I learned on the fly just avoid the grind soundsI didn't mean you Tyler, The 13B is/was not a common model.

Another funny thing--less gears are ground when relaxed, in a good mood, chewing gum justI'm sure I don't shift them properly I learned on the fly just avoid the grind sounds

Some days I'm a professional like a machine doing it some days I look like a Amish chick churning butter on top of a rock crusher......Another funny thing--less gears are ground when relaxed, in a good mood, chewing gum just
watching scenery go by. The harder one tries---------Then you have the guy that can't chew gum
and drive---there are those, my old company was full of them.
Actually I wish the 18 had never been invented---it was/is unnecessary with the lower range
13B. The trouble is the final drive gearing in allot of cases. Now a 9 spd with a 4 speed aux,
that works real well.

Plus a 10 spd like a 16210C--It has the same ratio in low and the same ratio in top hole
as a RTLO18913A 13 spd--But because 1st is so low it's actually driven as a 9 spd.
Out here a 10 spd is a turd with the long grades and 450 rpm gear splits, same with the 9.
I've driven a few 18 speeds with a straight truck overloaded probably around 60,000, splitting low side is completely pointless unless you're wanting to shift up a hill. It's just a more expensive heavier 13 speed.
I really like 13 speeds because of splitting high side it's so easy to grab the gears you don't grind nothing and just slow down with Jake's is fast. I can't believe a professional over the road driver wouldn't split all the high gears.
Mg84, every big truck I've driven you barely RPM the low side and you can shift it without grinding easy. I can't remember to exact but on high side it's around 4 or 500 RPM I think
18sp in a straight truck? Didn't see that coming.
