I need you to go to a auto parts store and have your car scanned for codes and let me know the exact code numbers not code descriptions?The transmission code be shifting hard to protect it from the clutches slipping because there is a pressure issue.We need to see what codes you have.Get the codes scanned when its shifting hard.
