05 Colorado 4x4 4L60E Problems
I?m having issue with no third gear. I went into the scanner under Controls and Special Functions and under Command 1st Gear 2nd, 3rd and 4th. I hear a click on all but 3rd. So what do i do next?

I checked the ohms on both solenoids and I got roughly 22 ohms.

I’m running a Stock Colorado trans tune.

3-4 clutch pack almost every time. As a test you can try jacking up the pressure to see if it engages 3rd...but that is just for diagnostic purposes. Better not to drive it that way.
