What the heck is the deal with AC Delco part numbers?  For the PF63 I’ve found 3 different part numbers. 
My 2023 5.3 manual says to use GM part number 12707246.

I’ve found 2 other GM part numbers for a PF63. 12735811 and 12731742. See pics.

Yes.  Same filter, different p/n based on how they are packaged.  There is boxed, boxed bulk pack (case of 12) and then bulk pack unboxed (case of 12).  And there's also the chance of old stock under a previous p/n too but still the same PF63.  

 

As for the "PF63", it was originally PF63 (before the eCore construction), then went to PF63E (eCore construction) and now all the eCores had the E dropped so back to PF63.  

 

Regular PF63 are still the eCore construction but its the updated eCore, UPF63R the ACDelco Gold filter is still built the way the older Duraguard filters were pre eCore.  You can loose sleep reading about eCore on the Bob Is The Oil Guy forums, but plenty of them are put on cars day in and day out and they work just fine.  Sure, there are higher end filters out there but the regular AC Delco works just fine for 95% of the people out there.

Thanks for the info! I’ve done a lot of searching. Just read that the GM numbers mentioned have superseded to the 12735811. I tried inputting the numbers into a couple GM part sites. The sites I used listed 12735811 as the current and shows it replaces the others🤷

I called my GMC parts department this morning. Gave them my vehicle information and the part number specified in the owners manual for the PF63. They confirmed the latest GM part number is indeed now 12735811.

Forget to mention that newdude’s comments are also correct. While giving me confirmation on the latest P/N, the dealership parts guy also mentioned exactly what’s in new dude’s post. Dealers purchase in different quantities and different origins, which change the part numbers accordingly. 
He also said P/N’s in the owners manuals are out dated before they are even printed! He went through the P/N history with me. My 2023 has had 2 revisions in filter numbers since my owners manual was printed. Of course some that change was due to Covid 19 supply chains.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I have never seen GM instructions for the other trucks as per the HD with the 6 speed or the half tons but had got the impression that the HD trucks with the 6 speed were not having the same problem that the 10 speed and pan presented. Also video that I have seen of the HD 10 speed with the gas engine starting in 2024 model year showed that it was a real struggle to even make it work when pulling down hard on the exhaust after undoing the exhaust hanger bracket on the side of the transmission as after all there is little room for the pipe to even go down behind the Y joint as it soon would hit a frame cross member. Also that they had tried just like I did with the gasket off and no way was that pan coming out any way they tried to manipulate the pan. From that as well as the local transmission shop talking about the pain in the rear issue, I was not expecting my pan to come out because GM shows it was not even intended to come out without dealing with the exhaust piping.    It would be nice to claim, here's what you do and its easy to remove the pan guaranteed on any HD truck with the gas 10 speed but dollars to donuts the next guy trying what I did would not have the same luck as the exhaust was just manufactured slightly different and be pissed off at my claim that the pan comes out with no issue. Its more of a try and see if your particular truck might work like mine did .... or not !.

      Sorry I didn't see this until now, but it works on both the 6 speed and 10 speeds, as well as all the half tons too.

      Engine vibration after motor mount replacement.

      By 1998sleaze · Posted

      Hello, I have a 2018 GMC Sierra 1500 that I recently changed both motor mounts on due to the driver's side being blown out. After replacement I seem to have a steady vibration that I can feel in the pedals and the back of the seat. At this point I'm convinced that the aftermarket "Anchor" branded mounts I used are not performing as well as OE, the only real reason I ended up using the mounts in question was because my local dealers were out a few months to get a Driver's side mount. I've tried "Neutralizing" the mounts according to the motor mount TSB published for these truck to no avail. My trans mount is also in great shape and seems to be absorbing vibrations swimmingly. As far as I can tell there is no issues idling, my idle RPM is steady and I've recently put GM plugs and wires on, however, I have not cleaned the throttle body or intake valves. Any one else have a similar experience with aftermarket mounts? Patience certainly is a virtue that I wish I exercised here. Thank you!
