After changing my ATF for my Toyota vitz 2009 1000cc I noticed my gear gets stuck in 3rd and won't go further and i see my check engine light on.

P0963 is the code detected after the scan.

pressure control A solenoid circuit high -- check wiring and connections to gearbox and then it's internal wiring

Vitz 2nd generation require CVT not ATF.

My mechanic made me replace the whole control valve system in the gearbox .but still after that the vehicle speed isn't smooth. It takes too long for the gears to shift. You have to accelerate for a long time before you get the speed. And immediately you take off your foot from the accelerator, the vehicle slows down like you are braking.
