Status Update: The Cougar shifts properly now. It was the MAF sensor causing the issue. I unplugged it and gave it and the throttle body a cleaning with one of those kits from Wally World. I reset the CEL code and so far after romping on it, the code for bank 2 lean is gone and it shifts at red line when floored. I still have my transmission shudder but I'm going to change the fluid to Mercon5 and see if it gets fixed then. At the same time, a J-Mod will be done. If I still get shudder, I'll throw in some Dr. Tranny Shudder Fix.
My Sig. broke and I must buy a new one from Sears...
