Why would doing this hurt anything? I have been doing it for 12 years? Daily.
what year trans is in your car Geno?
the pre-98 cars had a POS one way clutch that was upgraded in 98.
the 93-97 cars were the ones you "really had to worry about".
BUT.. I beat the dogsnot out of my 95 box...daily, and weekly at the dragtrip.
But it was Jerry that said "dont do it", and I generally take what he says as fact...and consider myself lucky for "getting away with it".
You know how it is, though.
For years.. you "get away" with something and the DAY you find out it's a NO NO, something blows up.
It's almost as if "ignorance is bliss".
On my svo mustang I drove it about 75K with a broken piston skirt.
it made a horrible noise...
Within two days of a friend of mine saying "that's a broken piston" the car lost all oil pressure.
pulled the pan and both peices of the broken skirt were in the oil pump pickup screen.
literally...I beat the snot out of that car, and it didn't BREAK until I "learned what the problem was", then it promptly CRAPPED.
ignorance IS bliss.
