I have a question that I’m hoping someone can help answer. I have a 2008 Silverado with the 5.3 and 39K miles on it. Up until now I have always taken it to the dealer for oil changes but I decided to do it myself a couple days ago. They used conventional oil with AC Delco filter. I put Mobil 1 synthetic and a Wix filter back on it. Before this my idle oil pressure was 20 PSI and cruising was 40 PSI. Now, however, my idle is like 35 PSI and cruising is around 50 PSI. Any idea why the change?

Where might I be able to find a quality valve body and plate? Sent from my iPhone using Tapatalk

I have the RPO M30 which means it’s just a 4l60e right? Not a 65?

Hello al! I have a random question and hoping you all might be able to answer it. I have a 2008 Silverado 5.3 with the 4L60E in it. Truck only has 36,XXX miles on it. I used to have a 2004 Silverado with the 4.8 and 4L60E in it that was junk. Had it rebuilt at 80,000 miles and it started slipping again around 120,000. So my question is are the newer 4L60’s any better or improved over the older ones? Sent from my iPhone using Tapatalk

Just curious why the 07-13 trucks are on the same forum as the 99-07 trucks. It kind of makes it frustrating trying to see stuff relevant to my 2008 Sent from my iPhone using Tapatalk

Do you ever put it in 4 hi and drive it a short distance to keep everything free like the manual says? Sent from my iPhone using Tapatalk

I put a sub under my rear seat in my 2008 Silverado with factory head unit. I ended up using the same LOC you did (bass control knob Is nonfunctional on mine). If your amp has high inputs you can splice into the wires at the back of the head unit to get all 4 channels and run them back like you would RCA cables. But even though I thought I knew what i was doing, when I pulled the head unit out and saw the multiple plugs I lost confidence in that plan (couldn’t find reliable information on what is what) and just tapped the door rear speakers harness in the pillars. That’s the best I could come up with it, works fairly well.

Are you sure you replaced the turn signal bulb and not the side marker light? Only thing I could think of to make an orange bulb look white is severe over voltage which I don’t think is possible in a 12 volt system or the orange film has already failed

When I had my 2004 the cluster itself went bad. First lost the oil pressure gauge and then fuel level and then one day the whole thing just died on me. They’re a known failure for the early trucks. As far as the OBD2 not reading, check and make sure that your 12v accessory and cigarette lighter fuses are good. Ran into that one day, couldn’t get it to read and come to find out that they OBD2 port runs through those plugs for whatever reason. Sent from my iPhone using Tapatalk

Wait... title says 2011 yet post says 2001. Which one is it? Sent from my iPhone using Tapatalk

I’m not entirely sure but I would say just take your stock shock extended length and add 3 inches to it or as close as you can get. Sent from my iPhone using Tapatalk

Sounds like you’ve already made up your mind just by the way you talk about flowmaster lol Sent from my iPhone using Tapatalk

I would probably sand it down and hit it with a rust converter paint to make sure you got it all and then primer over it just for extra protection. Sent from my iPhone using Tapatalk

Hello all, I’m wanting to install one of those led strips under my tailgate that do the brake lights and reverse lights. Most all of them come with a 4 pin trailer hookup but on my 2008 all I have is the 7 pin. It seems that I saw somewhere that someone makes an adapter that plugs into the module under the bed and lets the 7 pin hookup pass through it while also creating a 4 pin out. I would love to do this instead of hardwiring like I did on my old 2004, anybody know who makes this adapter or what it’s called? Thanks in advance!

You would likely need new fenders, grill, and bumper to make them fit. The Sierra’s headlights are slanted on the back whereas the Silverado’s are vertical Sent from my iPhone using Tapatalk
