Brian Blaylock Posted December 6, 2013 Share Posted December 6, 2013 Does anyone know if it is possible to add a stick to a 12 speed transmission to make the range selector manual and do away with the air shift so that it would work like the old 2 stick 6 speeds?

Superdog Posted December 6, 2013 Share Posted December 6, 2013 I don't know why you couldn't as the first generation 12 speeds had 2 sticks. Quote Link to comment https://www.bigmacktrucks.com/topic/33771-12-speed/#findComment-220113 Share on other sites More sharing options...
Brian Blaylock Posted December 6, 2013 Author Share Posted December 6, 2013 I didn't know how far fetched of a idea it is it would solve a lot of problems I am having with the air shift on the truck I drive at work Quote Link to comment https://www.bigmacktrucks.com/topic/33771-12-speed/#findComment-220123 Share on other sites More sharing options...

Lmackattack Posted December 7, 2013 Share Posted December 7, 2013 If I recall the early version 12 speed was a 2 stick...i think the 2nd stick was just for the deep reduction used in 1st....the splitting was still done with the splitter on the main stick?Someone chime in if I wrong...

leversole Posted December 7, 2013 Share Posted December 7, 2013 That is correct! The second stick was only for the front compund (deep reduction), later models had an air flipper on the dash...You could machine the rear comound shifter cover to add a linkage and put a third stick in! Then you could do a video like that peterworth guy did "grabbin three sticks!"http://www.youtube.com/watch?v=8lEYaTvvq4g&oq=shifting%20three%20sticks&gs_l=youtube..0.5j0.3863.7309.0.9701.21.20.0.1.1.0.213.2409.4j15j1.20.0.eytns%2Cpt%3D-30%2Cn%3D2%2Cui%3Dtl.1.0.0...1ac.1.11.youtube.sYJFGDzC4aE Quote Link to comment https://www.bigmacktrucks.com/topic/33771-12-speed/#findComment-220217 Share on other sites More sharing options...
Brian Blaylock Posted December 7, 2013 Author Share Posted December 7, 2013 Thanks for the info I didn't you a top cover off of a 2 stick 6 speed could be modified for this purpose or not Quote Link to comment https://www.bigmacktrucks.com/topic/33771-12-speed/#findComment-220231 Share on other sites More sharing options...
rsb502 Posted December 7, 2013 Share Posted December 7, 2013 You can add the stick for deep reduction but your question was fr the splitter and no I don't think you can add a stick to shift from low to high in each gear, the shifter also shifts neutral/reverse and all is done with air shift in one cover.

BAD DOG Posted December 7, 2013 Share Posted December 7, 2013 You could probably find the stick for the deep reduction somewhere but rigging up one for the high low reverse and neutral is more of a headache than it's worth, but it probably could be done.

Vladislav Posted December 7, 2013 Share Posted December 7, 2013 Ken, you must be lucky with your only five.Less miss shifts and minds to remember wich one you drive and what to do with others.At least until you have no plans to run fat chicks in the trailer. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/33771-12-speed/#findComment-220274 Share on other sites More sharing options...

rsb502 Posted December 7, 2013 Share Posted December 7, 2013 Yep its a 13 speed, I got a couple emails and texts when that video came out asking me to do it to another truck. I like his showmanship, popping it out of gear every time he splits the gears makes it look like work.

Mack Doctor Jr. Posted December 7, 2013 Share Posted December 7, 2013 I'd make a bracket to mount the air splitter to under the cab and fab up a linkage for the shifter to push/pull it. But that is still defeating the purpose for what he wants to do.

But that is still defeating the purpose for what he wants to do.that's how the three stick kw was done, I actually made a bracket to use a push pull air valve froma dump truck tag axle/tailgate to shift from under the floor but I never have installed one yet, I kinda lost interest after everybody else did it. That's kinda what happened to me with chicken lights, I used to love em I don't know how many I had on the 04 Granite I had, lots but now everybody has em so I am going low key with the 85.
