Y 1.2 Ecv-t - Problem with transmission HELP!!!

[Carlos Vidal]

I had a problem with ecvt and i'm not expert with this car. I bouth it recently.
With the engine turn off I can change the gear from P to L even so with a little more effort.
When in P I put engine running, it's very difficult or even impossible to change to R or D / L. Sometimes scratches...
After the gear R, D or L is on the car moves and accelerate well. Only when I almost stop the car, in signals for exemple, it shake a little.
Can you help me, with your experience with your ecvt?

Thanks,
Carlos Vidal
