Tranny seal replaced, so why the jerking?

Ok well I fixed 3 of my problems. My exhaust was welded, fender dent was knocked out and tranny seal/gaskets/fluid was replaced. My question lays here…

When I was going about 80 coming home I decided to punch it, when I did it seemed like it took a second to get in and when it did catch it jerked me. So now im like wtf? Maybe it isn’t the smartest thing going 80 in a 65 and punching it to go 90+ to get around some stupid gerbil fuck who has been infront of me going slow when someone is in the right lane and then fast when there is no one there. Im sure we have all had that kinda dick. Off the technical note it was funny that it was atleast a 300 plus pound fat dark woman with a handicapped license plate in her newer pimped out Monte Carlo.
