No obvious oil leak, checked lines, we're fine so I'll just keep eye on it.

Changed hose set up, boost dropped to 12 lbs, also builds slower. Can't believe the new solenoid only lasted one year!

New issue, took 2 runs from a stop and it wouldn't shift out of first, had to lift. Shifts fine in normal driving???

well, drive it a bit and look for oil again...

yep, always rises a bit slower in tuner mode...you will have to shorten the rod to get more boost...12# is what the stock actuator spring gives you at minimum tension.  Strange that the boost solenoid is bad..they are not usually failure prone....Check and see if one of the wires has 12v on it when the key is ON.  Think it is the pink/blk wire that carries the power

I will leave the tranny problem to Ed.  Governor spring is all I can think of.

Governor spring fell off or you have a hard internal problem. Check the spring first. Easy fix.

There is a 4 bolt cover behind the valve body to pull the governor.  The governor will usually come down with the cover. Be careful the spring that fell off will fall out too. I really can't tell you how to fix it yet. You have to see what when wrong first. Spring fell off, broke, weight jammed?

Okay, about all I know about a transmission is P means park and D is drive. Do I drain it ( it has a drain plug installed in the pan) and drop the pan to get to this 4 bolt cover? Or should i just take it somewhere?

Yes, the trans pan has to come off and 4 + quarts drain too.  If you have a shop you know that will work with you then take it there. If not the repair can cost you a few hundred dollars.  It's easy to do if you kind a know what your doing and have basic tools

Looks like he has raised the price to $20.  I don't know how anyone can successfully own a Buick without a manual

update, didnt have the guts to tear into the tranny so took it to the shop that rebuilt it. He tells me the tranny is fine. Says the motor has a miss or fueling problem and it is causing the problem at the 1-2 shift. It does shift at WOT, it just has this weird prolonged sliding shift at about 4000 rpm's. he says the engine misses or runs out of power causing the tranny to do this weird shift. I have always felt this slight miss crusing when just a tiny bit of power is needed. Taking into a shop to put on a machine Friday morning to diagnose issue...I hope.

Is he blowing smoke? Very reputable place, 30+ years in business. I have always felt the miss thing he is saying is the cause? Could this be or is it not a possibility? again I dont know crap about transmissions! he also was adjusting some cable by the thottle body that did have an effect, he put it back to where it was but it must be off a bit because now it goes into over drive with a lurch.
