  1. thanks, this is a big help. I used the diagram to connect one of the number 4 inversion valves. I have two of number 4 inversion valves. two of the three ports have tees in them with fittings for two for two lines.
  2. I have a 1993 Superliner with an e7 400 and a mack 12 speed trans. the air lines have been all cut or ripped out for the air shift. the number on the trans is T1070b. It has one pressure control valve and two other valves along with an air filter bolted to the side of the trans. But air lines are half missing or cut. does anyone have a schematic of how the should be connected they could post? thanks.
  3. We have an 89 superliner V8 12 speed that was in a flood now the clutch won't release. any ideas on how to free it up?
  4. 1993 e7 400 in a superliner. want to see if I can bolt the quad box to it. just for fun. not a working truck. I just like a good challenge.
  5. do you know what clutch Mack was using with them?
  6. does anyone know the last production year for a Mack quadraplex trans?
  7. we have a 2013 MP10 in a Titan. it won't build boost past 30psi, and falls flat on its face. It has been back to mack on and off for over a month now. Injectors changed, turbo changed, egr changed and some sensors. any input here would be great help.
