For the Road Warriors: Why are Burnouts in Drive a Bad Idea?

curious. how many here have actually destroyed a trans, that otherwise is properly taken care of, by doing burnouts on street tires

That’s a loaded question, small tires burn easily with little wear on the trans per say. Big tires and strip use are harder on the drivetrain. 904/727 trans lend to 2nd or high gear burnouts for high abuse in boxes at the track. I always ran street radials and tried to bypass the water. When successful I did 1 quick then 2 hard and left in 3 with Modified transgo equipped unit. If I had to get wet then I went 2,3 and out. So if cruising around having fun 1,2,3. You have to look at band apply and how that causes heat in the tranny. Folks have been smoking tires in these cars long before I got one. One thing I know is if you ever have a rear end or shaft failure you better check and replace the sprag and overrun clutch or you will likely have a bad day on your next trip.
