ITS F****ING FIXED!!!!
WOHOOO!!!!

I am so F****ING happy right now. My transmission issues are GONE!

I have been driving it for a day now after the repair, and have had no missed shifts, and no thunking on deceleration.
I replaced the A, B and Band Apply Solenoids, and that seems to have fixed everything.

I am so relieved that this is no longer an issue. This was the last attempt; if I didnt figure it out with this fix, I was going to sell it. Now I can keep driving it. Whew!

Thanks to everyone who helped me narrow it down, especially MSHardeman and Y33TREKker and super-special thanks to VXobsession!!!

You guys have no idea what a relief this!

Thanks again!
