1996 Ford Thunderbird LX (219k)
I have a 1996 Thunderbird with a v8. Between 2-3 and 3-4 when i ease off the throttle during a shift the whole car shutters for a second, as if its going over a sudden bumpy road. Yet at the same time it never shifts hard or slips, not even at higher rpm. My mileage is 217k but the car runs like a top elsewhere.
