Sephia 1,5 automatic - ANY HELP PLEASE!!!

I have HOLD light flashing. It happens 10minutes after starting (when it properly worms up). Then it goes much higher in rpms to shift especialy from 1st to 2nd (goes over 3000rpm).

The real problem is that around here automatic tranny is rare and if I give my car to the shop I can only hope that it will survive.

I need ANYinfo on diagnosing, how to read tranny error code, or repair material so that my friend who is a mechanic can do something about.

Thanks.
