what damage is caused when my 2003 tahoe was traveling at 60 miles per hour then thrown into park!
Most likely you damaged the sprag / park gear in the Trans? Keep driving it, when it starts slipping, you know why.
Possibly nothing. You might have got lucky.
My girlfriend did the same thing once to my 69' 396 SS Camaro automatic, It skidded bad down the road bad untill I yanked it quick back into drive. Nothing happened with the trans & rear end, it just shook us up a bit.
