Sorry about that long week due to this Tahoe problem.
So last week I go To Craig my Tahoe and it cracked up fun and ran but we’re not going to drive or neutral. It wasn’t the shift cable I was told it was the shift solenoid. I got one from O’Reillys looked up how to put it on took the whole valve body changed transmission, fluid and filter in the process . reinstalled it …by the way… did not see where a shift solenoid went .. So didn’t mess with it. Reinstalled it and it was not even crank up now it’s not showing that it’s in park or neutral or nothing. How do I check to see if it’s sending the signal to the car or what not I had it I know that Plug is tricky please somebody help help help.
