Hello. When I start my engine and drive my car(without warming the car up), I notice that rpm goes up to like 3000(car doesn't go any faster bc it's still in 1st gear). Then, all of a sudden, it comes back down(from 1st gear to 2nd gear, i think). When changing from 1st to 2nd gear, I hear this weird sound breifly( like it's kicking it back) After that, everything is normal. It doesn't bother me too much but, i am afraid it's bad for the engine or something. WHAT IS GOING ON? Is this related to differential? Do i need to have it checked soon? Please help. I REALLY HOPE IT'S NOTHING SERIOUS>>>Can this be caused by not changing oil when it is supposed to?
Thanks always. ... Justin.
