You need a diagnostic scan to find out what the code was trying to tell you. Even though it could be missing now but the fault would have been stored in the power control module (PCM).

Electrical faults can result in transmission shifting issues.

Thank you.
Do you recommend a shop in Beaverton for diagnose?
Once I did with Subaru they recommend for Knox sensor problem and I changed
again the engine check light came and now gone but car does not move.
Also, the signal light handle when put on right turn and off the click sounds on in the off position. Is there anything connected with the electrical ?

Sorry I am not able to recommend any shop to you as I am from far away. You can try your local parts stores for recommendations. They are in the position to know who is specialized in what.

Yes, this can be due to electrical issues. Low battery voltage would cause erratic shifting and affect engine performance.
Check the fuses and have the charging system tested. The signal malfunctioning could be due to its own fault, malfunctioning switch. That would have to be checked.

Hi, good news today I did a try, started the car and warmed up then put it on reverse gear and gave gas suddenly with a jerk like some brake was released then it moved back and drove for fifteen minutes in between put on reverse and drive gear it worked.
Now could you tell me whether I have to do any check ups on engine, transmission or electrical?
Thanks

I would suggest a check on the brakes. Seems like the brakes were locked and the handbrake did not release. This would result in the vehicle being stuck and you had the feeling of vehicle jerking but not moving when gears were engaged.

The increase acceleration had managed to released the locked brakes.
