C4 Line Pressure ?

I just rebuilt my C4 3spd AT and I installed a new adjustable modulator and I have a question about the adjustment of the modulator. The manual states that you need to check the line pressure at the various shift positions. The manual says to use a pressure gauge connected to a line pressure outlet port, but I was unsure where this port is on my C4. The only thing I can think of would be the tranny cooling line outlet. My thought was if this is where I am supposed to check the pressure, that I could install a small pressure gauge inline with the tranny cooling line and just leave it there. Has anyone done this before and am I on the right track? Thanks.

Jim

The pressure port is in front of the intermediate band adjuster.

Thanks Stuart. I am surprised with all the time I spant on that transmission I never noticed that pressure port. Where would I get a pressure gauge to check the line pressures?

Just about any aftermarket parts or tool store should have something.
