Starting at 20,000 miles I started asking the dealer to check the transmission on my vehicle. Very often the transmission shifts very hard to the point you hear and you feel like someone hit your car ( usually from 1st to 3rd gear ) and also when you shift it to reverse it slips. Dealer keeps saying theres no codes coming out on their computer. This always happens in motion on a city street.
