I get no symptoms- O/D light will just begin flashing. It usually happens on the weekend when I do most of my driving. After a restart no flashing but tranny slams between gears- then goes away after a day or two-- weekday driving is very infrequent and short-errands-yes I walk to work. AAMCO sz 740 the lockup solenoid changing the ratio- I'm think of getting it fixed Tues.
