OK my car is linking something here and there and i cant find out what it is... just everyonce in a while some smoke will come out from under my hood ...this just started a week or so ago. AND now today my shifter thingy (my car is a auto) has a hard time moving from P to R and R to N....Does this my somethign is wrong with my trans or is it just that somehting is wrong with the safety thingy on it?
