I'm sorry, i didn't really mean it as a negative comment, but when you're above 60mph with a AT teg, you would prob have to floor it for it to switch gears and finally go. That's what i meant by the transmission sucking, esp when you're goin uphill. It would literally take about 5-10 seconds for it to pick up speed even if you press it 3/4 .... it'll be stuck in fourth gear.

But i did suggest on any vaccume leaks, maybe the transmission fluid needs to be changed if it hasn't been already.
