518 Screech in neutral

Yeah, I've never done that one again!!! I'm running 4:11's and mostly drive around town, or runs on back country roads, only use the overdrive when on road trips on the highways. But what a blessing that is when I'm on the Interstate, to be able to drop the revs to 2700-2800 or so!
(Maybe it would be smart to double check the wiring for the lock-up switch...? But I hadn't been using the OD/lock-up, and since the screech only happened in neutral the lock-up clutch wouldn't be in the picture anyway, would it?)
