Did you adjust the pressure regulator?

No I dont believe that we did, we followed the TransGo TF2 instructions.

the front servo port you were in sounds as though its the one that forces release of the front band, so the reading there could be correct. The fact that the rear servo did not show pressure in manual 1st is a bit bothersome. Do you have the FSM for the car? this would give you pressures that should be present.

It is a '73 big block 727 that we rebuilt a put in my '74 Duster. I have a couple of books on the 727s, a fsm and a rebuild book. Both of which say the pressure should be in the mid 50psi range.

But, the more that I learn about the TransGo kit is that it raises the pressure and has you measure the line pressure adjustment differently than the FSM does.

I am thinking that I should call up TransGo and ask them what kind of line pressure would be ideal. Because I have no idea what is too much or what even would be right.
