I have PTS shift kit, billet internals, and PRV.
I have developed a flare in 2-3 shift.
The pressure @WOT is at 150 and it drops to 130 for the 1-2 shift and drops to 110 for the 2-3 shift. the drop only last as long as the shifts.

The tranny has been rebuilt twice (by two different guys since I moved) in the past two years and I am beginning to get really get pissed off with all the f-ing money I have dropped into it and still problems. I am letting the second trans rebuild guy have one more shot at it. He wanted me to do the pressure test to help him diagnose it.

Comments for what might be wrong are appreciated.
Thanks

Is that the press. all the time 150 @ WOT? That's low sucking @ filter or weak pump slide spring. Mine had a similar press. prob. put in a stonger slide spring & I think that's what fixed it.

No trans. guru just trying to learn & help.

your int/reverse boost circuit is no functional.maybe the oil signal pipe is missing on the valve body,or the pump is misassembled.

That thing is mammoth. It worked way better than that cheapy from NAPA I used last time.
