Well I got it back in the car. Went through the gears just sitting there and everything was around 200-210. Go out and take it for a little spin and roll into 3rd and spun the tires pretty hard. Come to a stop and now 3 rd is reading 150 at idle, and so are all of the other gears, but 1-3 go back up to normal when I am driving, which is around 230-240. Is that something to be concerned with? I'm guessing so?

Pressure at idle warm will almost always be less than above idle. The pump doesn't make full volume at idle. A pump in good shape will usually make full pressure by 12-1300 rpm.
What was identified as the problem?

He really didn't find anything that he could see. Pump was in excellent shape, tolerances were in spec, and all the air checks were fine. So everything I said seems fine? Reverse was around 200-210 and now it's around 150 at idle but goes back to normal giving it gas.

You need to have someone who specializes in racing transmissions look at AND dyno it.
It sounds as if your builder never determined the root cause of the failure. Until you do that and fix it, you will continue to get practice removing and installing it.

If you are happy with the work/results, I guess that's all that matters.
