Here are some preliminary pressures we checked last night. The pressures noted are what I'd call an average. It has a lumpy idle so the pressure gauge needles were shaking about with about a 15-20 psi spread. All pressures were checked at idle.

Line pressure:
Park: 170(ish)
Reverse: 130-140(ish)
Third: 170ish
Second: 170ish
First: 130ish

@ 1/2 accumulator port:
No pressure measured in any gear

@ 2/3 pressure tap:
Third: 170ish
Reverse: 20-30ish (it was about a 10 second buildup to this)
No other gears showed pressure at this port.

I dont know if these say anything to anyone else, but we found it a little odd that the first was dramatically lower and made us think it was an indication of a bleed through with the pressure.
