I have a 2002 cavalier with the 2.2 ecotec. Recently, after putting the car in drive and accelerating my service light pops on and abs light, and trac control off light. I can usually turn the car off and turn it back on and its fine.

But today I was driving and all of a sudden it wouldnt shift into second gear. I drove a little while longer and then it started to shift again, but then went back to first only/ Went and had the codes pulled, and it came pack P0753 wich is 1-2 shift solenoid valve performance... and P1860 TCC PWM solenoid electrical fault. What am I looking at here as far as what to replace? Should I get a new solenoid? Or maybe I need to get a flush due to junk being clogged up in it?

Thanks for any help!
