Had new TCM installed under warrantee, and dealer installed new pcm flash as well. WOT shifting is now crummy; burbles and pops at WOT upshift first to second, and burbles and pops even worse WOT 2nd to 3rd. How can I get the trans to shift as CRISP as it did before this flash?

I'ld just take it back to the dealer and explain that what they did made things worse and you want it fixed. Welcome to the forum by the way.
Poll wasn't there when I posted that and I didn't know you wanted people that had the TSB dones oppinions.

My 09 SRT has had all the flash updates applied as far as I know and that TSB was performed for certain. I think it pertained to harsh downshifts which did not bother me but apparently a lot of people complained.

On WOT upshifts, mine just shifts and goes !:bigthumb:

Therefore I suspect you have some other problem besides the TSB being applied.
