The switch that's in the dash is for deep reduction. I wonder if I run a air line from the regulator straight to the high side of the deep reduction cyl if I can avoid all those valves and just plumb the trans like a regular 1070?????

I have used as much of the 1070 diagram that I can make sense of. my truck has only one air regulator and two diverting valves, those are the ones I am having trouble plumbing.

Have you checked for any inactive faults logged? some times a vehicle speed or timing sensor fault can be active intermittently and for some reason you wont get a lightning bolt.

Hi guys I am working on a 1984 rws7 mack super liner. We bought this truck recently and have been trying to get it on the road. all the air lines are missing on the top cover of the transmission. I have been researching air diagrams and have only been able to come up with diagrams for trtxl1070 trans which is different than what I have. I am new to this forum and would greatly appreciate if anyone could help me out with the correct diagram.
