Engine rattle before downshift...... I just noticed tonight that when I drive around in drive (not OD), if I step it down to gas it a little, I get like a lifter rattle (like a dieseling sound). Does this have anything to do with a 2.73 to 3.42 rear swap? I reprogrammed with my HPP3. I guess I never heard it before. I do run premium, but I also need an oil change. Anybody?

I've got the same problem. When the Converter is locked and I press the gas a little I also get a dieseling sound, it's really kind of loud. It started about a couple months ago for me. I'm also running 93 octane.
