my 2009 r55 S drove fine day before yesterday. got in today and put it into drive and no go. into reverse no go. into park and it graunches. checked cable to trans on top and its secure. put in a quart and 1/2 of trans fluid, no go. cleaned top and bottom electrical connections and checked for bent pins, all good. still no go. i have no fault codes. the wheels will hand spin in park when elevated off the ground. i had no noises or mechanical sounds from trans before this happened. Any input would be appreciated
