I was driving to work the other day and when i came to a stop sign, after waiting my turn to go, i let off the brake and hit the gas and it was almost like the car was in neutral. It revved up a bit and then dropped into 1st and took off. It doesn't do this every time, but it has done this to me 3 times now, over the course of about a month. Also, sometimes, it shifts hard into 2nd gear when accelerating moderately and gives me a little jerk, its not smooth at all. While in 2nd, sometimes while accelerating slowly/moderately it kinda feels like i have 4 plugs misfiring, so it feels weak and wabley. I'm not sure if that has to do with the transmission or not. I am currently at 71k miles on an '01.
