When driving I feel shudder at lower speeds, medium speeds and sometimes faster speeds. Makes feel car motor or transmission can leave me in middle of highway or street compromising my safety. Vehicle can be inspected at any time. The dealer indicated fix was transmission oil change with additives, which I did, which cost 700.00 and the problems is still there. The vehicle has not been inspected by insurance but the dealer has as stated above. I bought vehicle with 46k miles and after about 1.5k it stated happening. Vehicle now has 50k miles. No codes have displayed.
