Tranny rebuild gone wrong

Here's one fer ya!

Just got my tranny rebuilt, under warranty because the torington bearing between the tourque conv and whatever is next to it bit the dust.

They've replaced every sprag, fernortner, purple fanozinator, muffler bearing etc in the case. I also had them install a transgo kit. Now, it's back together but still at the shop. Road test gone wrong. Car starts out in 2nd then shifts directly to 4th. Turns out there is now no power getting to the solenoids. This was working when I brought the car to them two weeks ago!

Does this sound familier to anyone and what might you suggest. The tech and myself are very frustrated.

Thanks in advance.
