TH350 woes

[RedRoad]

History: Rebuilt buy a supposed quality shop less than 2 years ago, less than 6000 miles since. Here is what they said they did

TH350 Performance Package includes

Alto Red Eagle Clutch Plates
Kolene Steels
Alto Red Eagle Band
Teflon Rings
High Endurance Gaskets, Seals and Bushings
TransGo Reprogramming Kit

I added a trans cooler and have run a temp gauge since new and never been hotter than 190*. Royal Purple synthetic since new, cast B&M 3 quart sump.

Today I went to the store which is only a mile a way, no problems or weird noises. Got back started the truck, shifted into reverse no problem, then to drive again no problem. Drove out of the lot and noticed it wasnt shifting to 2nd or 3rd. Pulled over and went through the detents put it back into drive and took off, same thing. Got home checked the linkage and everything looked good, a bit loose but no binding or anything. Now no other gears including reverse except 1st.

Anyone have any idea what might be going on?

Did I mention I HATE automatics!!!!
