    AutoStop Eliminator

    Put one in our 23 Tahoe right after getting it home from the dealer and no rattles. I did tie wrap it to something so it wouldn't rattle. Jay

    Anyone used UPF63R on 5.3L?

    Dealer doesn't know what they are talking about. They are interchangeable. I have read on Bob is the oil guy that the UPF version is in fact a relabeled mobil one filter. If the dealer telling you not to use it and this is where you would have warranty work done I would stick with the PF63 just...

    Another oil weight question

    The L8T doesn't have DFM. As for the low temp oil viscosity, DFM (and AFM before it) is not active when the engine is cold. It's active when engine temp is above 165.

    What Oil for a 6.2 that passes the PICO test?

    No, the bottom 3 on my list are 3 different types of mobil 1. Mobil 1 Fs is a european oil and may be harder to find in the US.

    BREAKING: GM is officially recalling the L87

    That's not an issue, it's only a small circuit that remembers the on/off switch position and won't cause issues with programing. If you have work done where your dash is worked on where they might see it I would remove it.

    Transfer case swap? Single speed to two speed

    I would think the wiring and controls would be the real problem. Everything is controlled by computers now so it would also take a programing change to allow it to work and I don't think there is anyone that can or will do that.

    Random Electronics Questions

    #2 would require a change in the BCM programing or custom wiring. #3 are you asking to see the actual gear it's in? If so you need something like Banks iDash or Edge CTS to see that.

    iOS 26

    There have been reports of a wifi issue in ios 26 with some phones and that would cause issues with carplay. ios 26.1 developer beta was released yesterday and would expect the public beta today or tomorrow which may address the wifi issue.

    Red fluid leaking 2025 AT4

    Based on your post on area of the fluid leaking it's probably from the transmission. You could look for a loose or leaking cooler line or check the trans pan bolts to see if any are loose.

    Red fluid leaking 2025 AT4

    Only 2 things that have red fluid. The transmission and the transfer case (if 4wd). The both use automatic transmission fluid.
