OH ****! ARRRGHHHH
I had a friend a lifetime ago that had a 67 Chevelle. 327 and powerglide. He did it on purpose going about 70 down the interstate. He locked the brakes down so it would make the shift, came off the brakes and stood on it and did an at speed Rockford turn around. He was one of those people who could just drive the crap out of a car. He shouldda been a get away driver. lol That transmission never said a word. It just kept on truckin.
