I have a 2007 GMC with the 4.8l. with 95,000 miles.

I've been getting a check engine light with the P0120 code referring to the TPS sensor. So, I figure it's time to clean the throttle body first.

Anyone have tips for cleaning it? Does it have to be re-set if it gets unplugged or should I just disconnect the battery?

  That's certainly good to hear that there was nothing alarming on the cover magnet volume wise or chunk wise of metal. I don't recall if the Banks cover holds more oil than the factor cover, what volume did you estimate that it took ?. As to the transfer case I assume you bought whatever brand you wanted of a Dexron VI automatic transmission fluid. Have you changed the automatic trans fluid at some point and actually I don't recall if your truck is the gas or diesel version as that makes the difference as to which transmission and oil type is required in 2023. The problem with my truck is that its the gas engine with the 10 speed and I've not yet attempted to see if I can drop the pan as the silly exhaust is right in the way and I do not want to touch the exhaust system on the manifold end if I can help it, the diesel does not have the Y pipe style exhaust under the pan so is not an issue to remove the pan.

  I have a 2014 GMC Sierra 1500 with 5.3 litre, with 400,000km. I drove it one morning and when starting later in the day it would crank but not start. I figured it had to be the fuel pump, SO i replaced the low pressure fuel pump in the tank. The problem persisted the exact same way, crank but no start. Checked a couple plugs and was getting spark. I then replaced the high pressure fuel pump under the intake. But the same problem persisted, it tried to start right after the high pressure pump replacement for a few seconds but then just cranks. I plugged in a better scan tool with live data and I can see the low pressure pump has the proper pressure but the high pressure pump is only getting 1-3mpa, when the scan tool says it should be 14mpa. The scan tool says the lower pressure fuel is in the 55-60psi range and it hold this pressure when not cranking. But the scan tool shows the high pressure fuel drop down from 2mpa to 0. I am not sure where to go from here, any recommendations or experiences with this condition? High pressure fuel rail sensor replacement?

  Have you had any issues with your 2.7? I’ve only heard of a few with that kind of mileage so far. OP, I haven’t read anywhere that carbon buildup is an issue. Just make sure to use top tier fuel. They claim that it’s better than non top tier. I’m not sure about that considering my FIL has delivered fuel for years and said it’s all exactly the same.

  It's raining on and off today, but I was able to change the rear oil and cover before it started. I ended up getting the Amsoil 75W85 for the front, 75W90 for the rear, and the right fluid for the transfer case. I wanted a cover with a drain, so that's pretty much the reason for the aftermarket one. I have a Roadmaster sway bar and had to fabricate 1" spacers for clearance, so that might be helpful if anyone has that on their truck and considering the cover swap. Old oil had 60,000 miles and just the slightest metal fuzz on the magnet; everything looked super nice. Fourth pic is just to highlight the spacers to accommodate the cover. Those bags sure make it easier than the old siphon guns.

  I haven’t heard of any with that kind of mileage yet. I’ve heard of several with over 100k miles with no problems. Looking forward to others chiming in.
