I recently installed a shift kit in my car and I went to drive it off the ramps I have it on today and the transmission doesn't seem to be acting right. In park if I hit the gas at all, the car lurches forward as if it's in drive. The same thing happens in reverse. Also, it won't let me put the car in first at all. I was trying to work tranny fluid through the gears and first acts like it's a giant spring now and the shifter can't even get into it. I don't know what to do as I want to drive it soon and have no idea what could've gone wrong as there is only one way to bolt in the valve body and I went through the whole thing to make sure no parts were lost before installing it. If anyone has experienced this or has any ideas I'd greatly appreciate it.
