727 Hard Shift from 1st to 2nd...smooth into 3rd

Most assuredly it can.
Problem is, we don't know what was done to it or how.
You need to talk to the builder, and if he won't or you can't for some reason you might as well just look for a stock valvebody.
(Unless you want to pull the valvebody, open it up and take a bunch of pictures anyway)

It sounds like some mods were a little over done, but who knows.

Ball left out, drilled separator plate, drilled dams, sticky 1-2 shift valve bore, and any of these together.

Thanks for the reply. The shop is very reputable and do great work. I will talk to the manager and see if they are willing to drop the pan and check the valvevbody. I'm pretty sure they put a new stock valvebody in the transmission when they fixed the reverse issue. The only thing different was they had to find a valvebody that would work with the neutral/reverser switch so the reverse lights would work (i.e. go off when not in reverse). The old valvebody/neutral switch/rooster would not turn off the reverse lights when in drive or nuetral. They would stay on all the time except if the car was in park.
