904 with Turbo Action shift kit, no 3rd

finally got a PSI gauge on my 904, in "D" and 1st gear, with all the wheels off the ground, line pressure was 0-zero. ...??... yes zero. :wack: when it hit second gear line psi jumped to 8 psi. it never hits 3rd, so... .. I pulled the throttle lever all the way open while revved up in second gear and line pressure slowly rose to 90 psi, which is what should happen. :hello1: When I let go of the throttle lever then Line psi goes back to zero. In reverse there is also -zero- line pressure and the spec says 230-260 psi.

The service manual says incorrect Throttle Pressure adjustment will give bad readings out of the Line Pressure Port even when Line Pressure is set correctly. Since the other gears work fine, I am thinking this may be the case???? I have not yet checked GOV pressure. I know the Line Pressure screw should be 1,5/16" from the valve body, but Throttle Pressure requires a special spacer tool.. does anyone know where to find this tool or the length of it, or another way to set the throttle psi, and does this sound like I am on the right track???
