Hi Long time lurker , i have a 2017 Gmc Sierra 1500 with the 5.3with the 6l80e . Im a trying to add a auxiliary transmission filter. i wanted to go with the the derale part number 13005 in conjunction with a NAPA 1269 filter. i have read both write ups done by FL335i and cossack. But on my truck the lines are routed different i included the attachment below .I want to try use an AN Adapter fitting to replace the #2 which is the gm quick disconnect19210848 with something like Earl's Performance AN to Straight Cut O-Ring Fittings AT949094ERL. but im having trouble coming up with a solution for how to adapt the AN line to the hard line. i know the AN line is probably over kill but i want to install it and not have to worry about it leaking or blowing out because i drive alot for work. if anyone can give me an input on this and any ideas or part numbers that will be appreciated.
Excuse my chicken scratch but i figured it would help explain my ordeal a little better.

On my 2020 GMC Sierra 2500HD Denali I did a hood air induction vent swap for a chrome vent cover and while I was at it I added Led RGB lights inside the vent taking care not to restrict the air flow. Has anyone else done any chrome or Led RGB mods? If so lets see them please.
My 2017 sierra 1500 5.3 V8 threw p0500 and p050d. Took truck into service and mechanic recommend replacement of all 8 fuel injectors. Every cylinder reported a history of both codes. With policy calculator, job was quoted at 1,200. Mechanic explained that injectors could be one of three potential part numbers but they could not know until they did the disassembly. One possible part number is on a 3 month back order. How is it possible they do not know the part number before the tear down??
Recently lost my 4WD when shifting it from 2WD to 4WD. I have electronic shift dial on the dash. I've replaced front diff Encoder motor, T-case Shift motor. Last week after I swapped the Tcase motor the 4WD worked again for about 2 days. Now its out again. Ran codes on it today at Oreilly's and its got CO 387 and CO 374. Looks like the 374 is a 4WD speed Sensor? and that failing is throwing the other code 387? Any ideas on what the root cause would be?

Hey all, I have a 2008 GMC Sierra 2500HD 6.0L Gasoline. Remote start is not working.
This sucks a lot for those of us living in Central Alberta
Initially the truck didn't start due to a check engine light coming from my downstream O2 sensors. My catalytic converters were cactus, so I removed them, had the O2 sensors adjusted and the engine light disappeared. That was two weeks ago. The remote start worked for one or two days and then I started having issues with it.
At first the remote start only worked intermittently, maybe once out of every 10 or so attempts and it was random. Then it stopped working altogether. I press the lock button on the fob and then hit the start button. The park lights on the truck flash as if it's going to engage, and then nothing happens. No sounds either coming from it to suggest it's going to start up. I looked at a few forum posts and dealer recommendations and attempted fixes. This is what I've troubleshooted so far:
I start the vehicle manually, then attempt to use remote start. Nothing. I'm aware it only has two start attempts.
My lock and unlock buttons both work fine.
There are no check engine lights or lights of any kind appearing on the dash.
Hood lever sensor seems to be functioning. No hood open warning on dash. (Still may be a problem but I'd like to avoid replacing the latch and sensor unless it's my last option)
Oil pressure and coolant temperature are normal.
There is no extra key or key fob in the truck.
Hazard lights are not on.
Vehicle is definitely in park.
I replaced the battery in the remote. No dice. I do have a now remote on order just in case although it does seem to be communicating fine with the vehicle.
I finally found a blog that suggested that it might be the brake light switch. Apparently this can cause both the cruise control and the remote start to fail if it starts to loose it's marbles. I decided to test out my cruise control and unbeknownst to be me the cruise control will not engage either. So this morning I replaced the brake light switch (which was no easy task). I jumped in my truck to test drive it and it seemed to brake fine and the lights still worked when the pedal was depressed. Cruise control still would not engage (but I don't care as I live in central alberta and don't use it at the moment), but when I returned home, I shut down the vehicle, locked it, and attempted the remote start. It worked!! TWICE!! I was super excited, turned on the ignition to reset it, turned it off, jumped out of the truck and went to attempt it again. Nada. Nothing. No dice. Zippo. I've retried 5 times after turning on the ignition to reset it, and still nothing.
Can someone please suggest where to look next? Any ideas? Anyone had the same drama and found a fix? I don't want to take it into a shop, I know it'll cost an arm and a leg!
