Hi,

Transmission jumping first to third mostly. Sometime works properly. I think it is electric component failed, could be solenoid or one of sensors.

I would suggest getting a diagnostic scan performed to check for trouble codes and if any found, it would help in determining possible causes for the problem.

It sounds like you have a shaft speed sensor that is going out. Here is the locations so you can check it out. Also the shift solenoid could be shorting out as well. Here is a transmission wiring diagrams so you can check signals to the shift solenoids.
