I just bought a 98 gt convertible. It's auto, has a k&n pk kit. I think it is stock other then that. My question is when it shifts it's hard and fast, it chirps the tires 1st to 2nd every time I hold it to the floor ?? Also it shift at about 75km and 5,500 rpm, does it seem like it has gears?? I don't think it does. Any help would be appreciated thank you. I will post pics of car when I get a chance.
