How many rpms should my 3.6 be turning at 60 mph ?
So you are saying you have 225/60x16 tires?
You could have a different final drive.
How long have you had the car and is this a something that has not occurred before?
Do you have a check engine light on?
The transmission may not be going into overdrive or the torque converter is not locking.
