Hi everyone newbie here, need some help please! I just bought my first Nissan Terrano 2 1999 2.7td Automatic two days ago. I have noticed or I am maybe wrong and clueless as its my first automatic. However, when driving on the motorway yesterday the revs are at 4000rpm at 60mph and not changing gears it seems. Additionally, the speedo stick is not matching speed it gets stuck and twitches after 40 mins of driving. This was not happening during test drive around town. It has 125k miles when odometer displays correctly. Thanks
