This being the problem is next to none. Brakes went out in my old Regal and I had to put it into park to stop it from rolling forward (from about 30-40mph).moved the gearshift lever and the car rocked forward
Sound to me like it was two things.
1. The tranny/clutch had some problem already
2. You gunning it made the problem worse.
Now that I think about it, I had this same thing happen in my 89 Taurus SHO (5 speed tranny). I shattered the clutch. Did it sound like a Crunching Metal Noise, followed by a loud banging noise?
