Why won't My 1999 Chevy suburban shift out of neutral and go into any gear?

What is your question?

I was driving home stopped got gas and 9 miles down road all of a sudden my truck coasted to a stop. This is the first time this has happened. I couldn't get my truck to shift into any gear like it was stuck in neutral. I had to pay $500 for a tow home!! The tranny fluid is perfect and no leaks anywhere also no grinding or anything in transmission...

What makes this problem better or worse?

Nothing still don't move checked shift solenoid and they are good also.
