well usually when im driving down the road and i pound the gas to the floor it will drop down a gear and go up to 60 before it will shift at 5,500 rpms. but the other day i did the same thing and the rmps flew all the way up to 6,800 and i heard a clunk. and now im having problems on the upshift when the pedal is to the floor. When im driving down the road cruisin it will shift fine. If any1 can help me with this problem please do.
