Most big trucks had two or three stick transmissions back in the day. Essentially you had a gear shifter and a range selector. I don’t know enough about three sticks to say anything about that. That’s all been replaced by an air shifted hi/low range.Didn't mack have a transmission like that?
How far "back in the day" are you referring to?Most big trucks had two or three stick transmissions back in the day. Essentially you had a gear shifter and a range selector. I don’t know enough about three sticks to say anything about that. That’s all been replaced by an air shifted hi/low range.
Love the build!I wish I could find some pics from a build I did on my old 1990 K5.
I added the 2.72 planetary gear reduction using the factory np241 transfercase planetary gear set between my transmission and an aftermarket Atlas II transfercase.
The setup had a stick for the front gear reduction, and 2 sticks on the Atlas transfercase that controlled the front and rear axle engagement independently. I had a 2.72 or 4.3 to 1 low ranges... And an 11.70 low range with both the planetary reduction and the transfercase shifted to low.
So with the 4 speed transmission, there were what, 16 speeds.
The gear reduction was so low, the disc brakes on the Dana 60 and rear Corporate 14 would not hold the K5 at idle.
I dug up the old post on COK5 when I was building the setup. To bad the pics don’t work. That was a long time ago, but seems like yesterday.

I have near zero experience with it, as my mom was a kid back when you were slinging tires. My dad however, was born in 42 and he had told me some stories about driving two and three stick trucks. I’m curious now.How far "back in the day" are you referring to?
I was tire man for a trucking company in '74-'75, and all ours (International & White cab-overs) had either 10 or 13 speeds with air buttons. And none of them were new...

I've heard of more with two shifters than I've seen. Brown-Lipe made most of 'em as I recall.I have near zero experience with it, as my mom was a kid back when you were slinging tires.

What’s he hauling?? Fully assembled wind turbines?Years ago, maybe 2002 or so, I was buying some tires for my Freightliner at that tire place on Macarthur - just north of I-40. I had run over a piece of rebar on a job site, it was muddy, the rebar was vertical, it ruined 2 tires, cost me $600.
Anyway, I was chatting with another customer. He had a custom truck, built for oilfield service work. It had a 9-spd, with a 4-spd range box behind it, and a 2-spd axle.
Those Eaton 9-spd trans (indeed, most of the Eaton heavy trans) have a Hi-Lo reverse.
Dude had 16 gears, just in reverse.
I've had nightmares about driving that truck.
I asked him something similar to that, he said he could move anything he could hook to, as long as the tires would stick.What’s he hauling?? Fully assembled wind turbines?
