tjc transport Posted December 14, 2019 Share Posted December 14, 2019 (edited) we were discussing older trucks we drove today, and i remembered a late 70's early 80's superliner tractor i ran with a dump trailer back in the late 80's early 90's. it had a V8 and a strange trans in it. 13 speed air shift, but it also had a small about 6 inch tall deep reduction stick between the driver seat and main stick, but much closer to the seat than main stick. low, direct, and overdrive. but 4th and 5th were not reversed like most of the 13 overs from back then. anyone know what trans that may have been?

Brian L Blaylock Posted December 14, 2019 Share Posted December 14, 2019 Was reverse on the splitter knob or did you shift the main stick into reverse if it was on the splitter knob it sounds like a 12 speed Máck Quote Link to comment Share on other sites More sharing options...
tjc transport Posted December 14, 2019 Author Share Posted December 14, 2019 the main stick, reverse and 5 forward gears. air splitter was low, direct, and overdrive. then the small stick was deep reduction in first and reverse.

JoeH Posted December 15, 2019 Share Posted December 15, 2019 Did it have an auxiliary box behind the trans? Quote Link to comment Share on other sites More sharing options...

terry Posted December 15, 2019 Share Posted December 15, 2019 Sounds like a mack 12 speed, but reverse is on the air shift with direct and overdrive, the small stick is direct and low range. terry Quote Link to comment Share on other sites More sharing options...
tjc transport Posted December 15, 2019 Author Share Posted December 15, 2019 could be, it WAS close to 30 years ago. i guess i may be mistaken and reverse was on the splitter and not the main stick.

Note that when using deep reduction on these you only get to use first gear and one split! the rest of the box gets locked out when in first and low,low!

tjc transport Posted December 15, 2019 Author Share Posted December 15, 2019 yup, that is the way it was, deep reduction in first and reverse only. and now that i think of it, you did not split 5th because 4th over and 5th direct was the same so you skipped 5th direct and went from 4th over to 5th over. which would make it 12 gears Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..
