[Wayne]

You might consider looking at the vb, to see if it’s been drilled for constant pressure, even though it’s not at max line at idle.

I noticed that the vb plate was marked DJ, which was scratched out, and DC was scribed in its place. Anyway, the pressure readings at idle are 85 in p/n/od and 135 in rev. When shifting to the second or low gear position, the pressure goes up to 235 at idle. Has anyone seen this before?
