Transmission problem
 

Hey everyone, u have h2 2005, my transmission goes out of his mind.... 1to second gear is switching perfectly but from 2nd to third it's doing this" usally it must switch 2,5rpm but it makes 3- 3,5 rpm and at this moment i feel that transmission is at neutral and than switching and it is burning only 3rd gear package nothing else" pls help!

Fluid level? Mileage/ km's? How long owned? Just started happening?

On my ford that did that it was just the solenoid. I don't have the kind of experience with the chevy's yet.

Fluid lvl is ok, solenoids are all working, 56k miles and it has began about 2 week ago

And if one of solenoid is bad why it must burn only 3rd gear package? I can't understand this one
