Hello there!

Wrong, engine has proper power - i can ride up on any hill what i want. Real reason of the problem is that automatic-trans. isnt working properly, it auto-shift gears up, but it cant down shift, so you have to manualy down shift. It looks like engine doesnt have enough power, cause when you slow down from higher speeds (gear stays on 4th for example) its like trying to move vehicle from 0km/h on 4th gear.
