Recommended Posts

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.

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.
