I bought this suv used with 87000 miles. When i drive 30 miles or so without stopping the transmission will shift hard and bark the tires when leaving from a stop. This has gone on for a couple years and i have 167,000 miles on it now. Should i be concerned? ---

Take it to one of your local auto parts stores that scans computers and have them check for codes. If they find one, it will probably be a P-1870 code. Post back with the code/s and we’ll go from there. transman ---
