I was playing around with the car today (2000 v6 automatic) and decided to manually shift from 1st to 2nd instead of leave it in drive (D). When switching over to 2nd from 1st at about 4500rpm and floored I spin the tires pretty good and the transmission catches pretty hard it seems. Is this normal? Only reason I ask is because the car is completely stock and I have 2002 GT bullitt wheels with 275/40/17 on the rear. I thought is was odd that a stock V6 could do this but maybe its normal?
