It is your first (old) car with automatic gear?
Not easy to differentiate what is realy normal but you think is not normal.
Specially from distance.
Please think about selling the car before you put many money in a car what you dont realy want (slow and lazy automatic gear) . Nothing can make the crap xedos automatic good. In the future you get more and more problems with the gear, you have to change oil and filter every 30.000km, to have not too much problems( by other automatic gear is all 100.000 recomendet by empiric experience)
With the manual xedos gear you never get any problems.
Sell it and buy the car what you want and not the first what you see.
Its the best way to be satisfied.
If not and you want repair... Please specify it with make good videos with good Cam and good Sound.
