Local Apparent Friday

TCM is inside the tranny. Plug should be on the pass side iirc. Clean everything off real good, remove connector. Blow everything out, regrease with elec grease, and push it back on. Make sure you hear it click into place.

You would go lower gear ratio for towing, not higher, but it's a moot point as nothing is avaliable aftermarket. Best you can do is swap for the v8 ring gear which i think is possible and a different ratio, but my mind isn't in it right now. Theoretically the actual bolting of the two things together is no big deal. Trying to get it to run is a whole 'nother story.

Intermediate carrier bearing.

Yes.

Welcome! I ALSO came from the E chassis. Haven't looked back yet. Laf

Advanced is probably the only one left doing it at this point, at least that I'd call. 12-15k range.

51344 is wix. 1344 is napa. I'm discontinuing use of napa filters because they switched styles and manufacturers to Donaldson. I will try the wix filter next and see if it still has the old style gasket.

Or if it's your first truck and you're used to putting 32# in things, proper tp is at least 50 up front and 80 out back.

No problem. Pretty much all the regulars here are gurus.

Tons of options listed on Rockauto. I just ordered the heavy duty AC Delco variant, as 95% of my travel has become towing bikes, but I haven't installed them yet, they just arrived yesterday.

This is the correct answer. Those are the first years of each respective generation, and they cover all the years, so the 12 is the correct one to use for your '15. The '16 one is the one you would use through '21.

I am currently running the aforementioned 1344 without issues, although I will discontinue that particular filter (and all NAPA filters) in the future and look for a cross. Napa switched from Wix to Donalson as their manufacturer, and the new gaskets are terrible and prone to leaking. Twice I've had filters leak out of the box with the new style. Here is a cross reference chart, I will most likely go back to Mobil 1 filters, as they can be sourced at walmart inexpensively.

Whoops. That's localish to me too. Maybe I can snag parts.

That is odd. I have the torchbeams installed and they are wired properly and function as factory. Perhaps the units you received were faulty, although it would be odd to have a matching pair that were wired incorrectly.

Glad to hear you were successful
