Replaced ignition cylinder, New key, new transceiver, nothing works

Okay so I'm really having a hard time with this. I
have a 2008 Chevy Silverado, and when I start it
(sometimes) it makes a grinding noise like
something isn't catching like it's supposed to. I
replaced the alternator and got a new battery. The
only thing I can think of is the starter, but every time
I take it to get tested they tell me the starter passed
the test. I don't want to take it to the dealership
unless I absolutely have to. I'm sitting on about
170,000 miles. Any kind of insight will help.

Sometimes the radio or the CD player volume is so low and cannot be adjusted while driving. They both work, but no volume from the speakers, front and rear.

Most of the time they are very low. Sometimes it works normal. Also seems to mess with the speakers on the drivers side. Help!

I have a 4.8L 2008 Silverado LS with approximately 145,000 miles. Recently it started revving high in 1st gear and would NOT shift until I let out of the throttle. It revvs between 3000 and 4500 rpm's before it shifts regardless of speed. Just two days ago, after driving it for 30 minutes, letting it sit for about 30 minutes and restarting it - The ignition was delayed, and when it finally fired, it shuttered. Like it wasn't getting air or fuel. Up until this point, my check engine light had been on. When it shuttered, the check engine light went off, but I still have the same issue.

There is also acceleration lag in the other gears. When it goes into the passing gear, it revvs to 5000 rpms and lurches - I really try not to let it go to the passing gear.

I've replaced the evap emissions sensor, the throttle control sensor (but not the entire throttle body), and the throttle position sensor. At this point, I feel like it may be a vacuum issue somewhere or possibly electrical. What the heck is going on with my truck? Thoughts? Suggestions? I don't want to keep throwing money at it and hope it resolves the issue. I've seen similar issues for trucks from the late 90's to 2007, but don't want to assume the same fixes apply here.

while at cruising speed I punch it and it revs to 5 grand before it shifts is it torque converter or a solenoid I don't know please help!
