you dumb fuckers. i have been reading your posts. no one has any idea how this works. the pole closest to you has 5 gears. the other has low, high, and rev. thats it. it is a trx trans. it was called a 12 speed, but had 15 speeds. 5 high, 5 low, and 5 rev. i know because i have been a mack truck mechanic for 15 years. plus we haul a lot of turkey shit with 1970's r-models. they are all tip turbine engines with 12 speed trannys.
Dear lord.... The 12 speed TRTXL1070 had an air shift knob on the main stick with HI-LO-N-R. Second stick called the mud stick had just two gears, hi & low, you just used first gear on the main stick with the mud stick in low. later they replaced the stick with a switch on the dash, The transmission in the video is most likely a true Mack twin stick duplex/triple/quad box. That R model has a metal dash which was from 1963-1973 and the END(T)673 + twin stick was an option in an R.
The right stick is used just like a two speed axle, it's called split shifting- without a load you can use it as a 6-speed- you shift 1lo-2lo-3lo-4lo-4hi-5hi. This is completey different from a Roadranger 9 speed which is much more common these days- they also have 5 gears and then a 2 position air shift valve on the stick- you shift lo-1-2-3-4, pull the switch up and go back through 1-2-3-4. The actual shift pattern is lo-1-2-3-4-5-6-7-8. These are much easier to learn than the old split Mack 9
The left stick has 5 forward gears+reverse, the right stick has lo and hi range- to use all nine gears, you start in 1st on the left and lo on the right, shift the right stick to hi, then you shift the left stick up to 2nd and the right back to lo-then the right stick is shifted to hi-this is 4th gear- then the left stick is moved to 3rd and the right stick back to lo and so on until you get to 4th gear on the left stick and hi on the right- then you move the left stick to 5th, which is 9th gear
@killswitchdeath the left one is the gears and the one on the right is your splitter, put it in first gear, then put the splitter in low to start off, then run thru the gears... when you start to reach the end of your gears,, put the splitter in a higher ratio then start the gears all over again... it takes time but i started on a newer pete, that had the splitter oon the gear shifter... made it alot easier
@Jeffreyrno Would it be easy enough for a first timer to learn on? I've wanted to fix up a semi truck ever since I was little and hope to build a show truck someday.
Its not hard to learn shifting a twin stick. If you can shift an un-synchronized gear box (Fuller/Rockwell/Mack) then you can shift a twin stick. You just have to remember that you split the main gears (1-5) using the compound. I have a B61 with the 9 speed Mack duplex and its pretty strait forward. You can even shift it like a 5 speed when your unloaded. leave the compound in HI and shift 1-5. Although if you have a light load you may want to shift 1-4 in LO split 4 and shift to 5
Real Men have 2 sticks,love to hear an old Dog bark.Hope to have an old B-model.Scratch gears?
Even if you did,and you didn't,a Mack is so tough,you could put bolts in the Trans.and it would put out paperclips.Anyone that Critiqes shifting has never driven a twin stick.Keep kickin that Dog.
got a nice R600 hood, early model 60's nice shape, alot of new Mack chrome in the box,horns,split dogs,hood dog,mack script, bunch of stuff,new old stock owners manual and used shop manuals if anyone is interested. Had a 69R 600 quad box.
Dat is geweldig! Ik wou dat ik een kon rijden met zo'n versnellingsbak... ben al blij dat ik volgend jaar men automatic kan inleveren voor een manuele :D

I cant see your 3 confirmations.
Here are mine:
Would you like a link to the 12 speed brochure? tinyurl com (slash) 8yazx6n
Or how about take a trip to the unofficial Mack bastion of the internet called bigmacktrucks com and argue your point on there.
post explaining how to shift from experts who have driven them:
