Hello. I just bought an 00 GT (automatic trans) a couple of months ago and I don't know too much about cars. I was just wondering if its normal for the car to go into OD at low speeds (like 30-35 MPH)? Also, when i turn the OD off, it feels like it kicks in once I hit 3rd gear. I'll lightly hit the gas at this point, the RPMS will go up a little, but then it'll drop back down. If i'm going fast this won't happen, but if i'm going driving at a moderate speed (25-35 MPH) this happens. Is this normal?
