I have a 2017 chevy cruze. 96000 miles on it. Started to shake really bad. Loss of power. My rpms would go really high before it would shift. Took it to GM ,they told me it was bad fuel injectors. Went to drive it home it home. Rpms were still high before it shifted. I could drive it a few 100 feet then will just rev. Wait a while and it will go another 100 feet before it just revs. I changed the fuel injectors, I drained the transmission fluid and added new tans fluid. Checked fuses. I’m out of ideas . I’m hoping it’s not the valve body or the shifting solenoid. Any suggestions
