My stocker will stall ~ 3k with the Whipple however I have to leave at idle because of traction. Still a little worried that it may give up if I increase the power in the next couple yrs and I sure don't want to toast the tranny.

Mine does pretty good off the line stalled up. I'm happy with my converter. Was a good combo with the ProCharger. If I had a Whipple or Maggie I would have kept the stock converter because of all the low end power those produce.

You need to get the 4 digit code of the side of yours to match up to the replacement unit though, it's something along the lines of ACCA..
I looked into transmissions quite a bit and rebuilds are 3500 and up, new replacement units from GM and Jasper are around 3k, jasper I believe gives a 100k warranty too. I'd be just fine with a low mile used one and there's plenty of them out there since these trucks are still so new.
I called the best trans builder I know after going through probably 20 of them (worked as a tech all my life so I've been in a lot of trans shops with customer cars) and he said it's pointless to rebuild the 6L80 because to do it right it costs him near 3k and to make money he has to charge at least 3500-3800 to make a few bucks. Then he told me about it being cheaper to just buy a Jasper unit with a long warranty and put those in. I personally would still rather have an OE unit.
