Do not double post.
manual? auto? Please give your details per the instructions that were displayed to you. Thanks.
That makes sense. Isn’t supposed to be lower RPM in overdrive? That’s why it is overdrive.
6th gear is overdrive. In some cars, it's an extra overdrive. Google the gear ratios in your Jeep, you can probably find exactly what they are. Your engine burns less gas at higher speed when it's attached to a transmission in overdrive. The engine's turning slower than the wheels in that configuration. The only problem is the reduction in torque. Climb a steep hill in top gear and you will feel the transmission downshift because it can't provide the torque to pull you up the hill in top gear, and maintain speed.
