Does anyone have the spec sheet for line pressures, and the location of the line pressure port? I have a P0868 Low pressure code that I am trying to diagnose. The trans filter was just changed and ATF+4 was added to the proper fill level. The filter fit nice and snug in the seal, so I don't suspect the low pressure to be caused by the filter replacement. And . . . the code was present before the filter replacement. Original fluid was discolored, either indicating that it was never serviced, or there is a problem. I want to check the actual line pressure, in order to have a baseline for my diagnosis. Thanks!
