Getting some pretty nasty sounds from my transmission and wondering exactly what it may be. It seems to only make this sound when in Park or Neutral and also when the truck warms up, does not make this sound during start up when cold.
Truck has about 152,300 miles and i had replaced all the fluid, filter and two solenoids at 148,600 miles 7 months ago.
I'm pretty much expecting the worst here, but if anyone could give me some more insight as to whats going on besides it probably dying, i'd appreciate it.
Clips of sounds here:
I have an 06 Silverado with 215k miles. Has the L33 Aluminum Block 5.3 in it. It runs great, has good power, but has an odd ticking/knocking noise. It doesn’t make the noise until it’s been running for about a minute so I don’t think it’s exhaust. I also do not think it’s a lifter because it sounds more lower end towards the rear of the engine. Has anyone had any experience with these L33s knocking? It has been making this noise for a while now and it’s very annoying/embarrassing. I’m not sure if oil has anything to do with it but I use penzoil 5w30 full syn. Let me know if you have any ideas, thanks.
I was at the dealer the other day getting a tire replaced and I noticed I needed a coolant flush as its been 5 years and no previous one.
When I got home I checked the reservoir and it was grossly overfilled. I doubt there's room for 7oz of expansion in it. I know sometimes this happens because it needs to burp out some air so I've driven it a couple of times but it hasn't gone down yet. I've got one of these coming tomorrow to suck the excess out if it hasn't gone down tomorrow but wondering if anyone knows about burping these or how to remove air. There doesn't appear to be a radiator cap which is likely why the reserve tank is pressurized.
Since these are pressurized reservoirs, it seems that a grossly overfilled can cause damage as there's nowhere for the pressure to go except the weakest link which is likely a hose or fitting.
My question is do these heater cores have a valve or is coolant running to them constantly? It is dead summer and I want to avoid heat on full to see if it clears out if I can.
Also judging by design, it seems like it would naturally burp itself fairly quickly.
Before the flush my needle almost always stayed constant at 210 when warmed up, now it seems to fluctuate between the 197.5 mark and 210 which leads me to think either there's still air in there or the overfill is causing excessive pressure that is altering the temp.

Has anyone else had issues with their lower glovebox rattling on their Chevy Silverado?
If I open it and hold the lower glovebox down, the rattle goes away, but as soon as I close it it rattles on the freeway and rough roads. I've tried to re-tighten the bolts and put duct tape over the metal plugs, which didn't help.
Any other ideas?
