pretty sure I wasn't
I know exactly what you mean. It seems to me that the programming changed something in the torque converter clutch application, either the clutch is releasing at high loads where it didnt before or the clutch is being applied with less pressure which allows it to slip at high load. Its not gear specific so it most likely has to do with the torque converter. I have also noticed (not flash related) that the torque converter they picked is way too loose for the application. Of course, they did that to make grandma more comfortable in the car. IMO the stall speed of the TC in a car that only revs to 4500 RPM really shouldnt be 2300-2500 rpm.
