Why would you have 2 sticks anyway?. I mean on a 4x4 truck/car it sorta makes sense as one of them controls which tires gets power etc.

@TNFSDK read the rest of the coments please

Buying, restoring and mastering a quadroplex B81 with a 711 Thermodyne is definately towards the top of my bucket list. Until then, my '92 Ram with a 4 speed auto is the most diesel excitement I'll experience! Very nice driving here, though.

@t3o14. the only scania motor used was in '64 which was the first mack v-8 255 hp.

@rig jockey, how did you get a cobra radio to work on positive ground?

@bembeler american trucks are a lot bigger, heavier and have much more horsepower. this was the hot setup to manage 73,000 pounds in the eastern part of the US. our hills were short and steep. when you heading into a hill you downshift the front trans and leave the back box alone until you got power to hold it.

learned on a b-81 in 1963.

@TNFSDK if you look at 18 wheeler transmissions today they have what looks like a trigger on the shifter that is for switching from low to high well they didnt have that technology back then so you had to do it manually so you would have a main box with 5 speeds in it and a aux. (the second stick ) so you would go through5 in your main box then throw it in neutral shift gears in the aux box and keep on going thats what they mean withlike 5 and 4 (20) speed you had a 5 spd mainand 4 aux

Hi, I have been driving over the road for nearly 25 years. I remember these twins sticks. In later years they were almost exclusively Mack. The twin stick that I had driven at the time had one stick, Left Stick, as the shifter. The other stick, Right Stick, was a range finder. If anyone has driven a Super 10 transmission of today then you'll know how the right stick was used. Some models were designed as the Right Stick controlled a 2 speed rear instead.

My Grandfather used to drive trucks like this. The first truck my dad hauled a load of coal in was a twin stick tandem. Ive yet to drive one of these. We have an old B model mack with twin sticks. Im gonna have to try it.

Damn this brings back memories Ya had to wear your hat cocked and a pencil stuck over your ear and a cigarette hanging from your mouth.....You didnt use a clutch to start off from a RAD light.....you just tapped the throttle and snapped the first stick into low and off you go.....2 A,M on a brisk morning running down Route 1-9 through Jersey.....god damn I'd give a million bucks to do that again,,fuc this weenie world of airconditioned automatic trucks.gimmee a MACK...or my wheelchair dammit

@TNFSDK It also makes sense that you would read up on the topic before commenting.

That's way too much work for me, give me a good old Eaton Fuller 10 speed or a 13 speed road ranger.

@TNFSDK what your talking about is the transfer case, in a semi, it is the range lever (hi range,low range) we still have high and low range, but it is now done with a lever hooked to an electronic or air solenoid. we also ahve 13 and 18 speeds (along w/ a 15 speedd deep reduction) which requires a splitter

this guy is a trunk driving fool good job

I drove something similar for a concrete company in Portland, OR... the mixers were all Macks and some were double sticks... I think we called them "brownie boxes"... tough to learn but once you get it, can be a lot of fun... best part about driving a big truck is the shifting... man I miss driving truck!!!
