I'm sorry GG, I just hate it when folks repeat bad info and try and scare you into neglecting your vehicle. There are a lot of folks with high mileage rigs who would benefit from a flush, but are too scared because of what's been going around since before the internet. My personal experience spans 4 full flushes, 2 of which were 4L60 rigs, and none of them died. Filter changes on my 1500 would NOT get the fluid clean. That's worth exactly what you paid for it. I have heard the machine is the one that tends to kill them as it has a rather high operating pressure, and I have heard if your transmission is acting funny and you try a flush as a hail Mary it's probably going to kill it, but if you have a healthy trans and flush the way I laid out with the transmission's internal pump by simply removing the return line, myself and others have had real world good experiences and nobody here can take that away. Once you're past that hurdle, you can continue to flush on schedule and get the longest possible life from your transmission. For the time being, this likely plugged cat and VVT issue should take precedence. Best of luck!Please stop arguing over the flush guys, its not helpful here
So once that VVT code is all cleared up, any chance it's clean itself? Is there some sort of miracle juice you can pour into an almost empty tank to get it cleaned? Was the VVT stuff the cause of the clogged cat? Wouldn't want that problem coming back.So I officially know what the issue is thanks to removing the updraft O2 sensor... the cat is completely clogged so it will need to get replaced... as soon as I removed it, I was able to do 0-75 in about 12 seconds as to where before it would take 45-65 seconds... and as soon as the O2 sensor was put back in, it bogged down haaaaaaaaaard
My best guess is it was just the carbon buildup after 212.3k miles... I could technically put CataClean in the tank when I have low af gas in the tank but Im just gonna replace it since its bolted in on both ends, no welding required... Also just gonna replace the upstream and downstream O2 sensors while im at it so on the 27th everything will be here from RockAuto and she'll be good to go again! Also the VVT code and the misfire in cyl 3 is already gone, it was just the cata P0420 code at this pointSo once that VVT code is all cleared up, any chance it's clean itself?

You forgot about me. I already had my long, drawn-out argument with him over trans flushes and the logic thereof.Superchrged111 is the ONLY person on these forums who advocates a full trans. flush. The ONLY one.
Take that as you will.
Once a cat is plugged, it'll never get hot enough to burn out the accumulated carbon. The engine will run so poorly that it will just get worse until the vehicle won't run at all.So once that VVT code is all cleared up, any chance it's clean itself?

Way ahead of you there ^-^ Got a Cali Cert that is CARB Cert as well, as for the O2 sensors, I think I ordered Denso... It was that or ACDelcoGreaseGirl95 I forgot one thing. Since you are going to be moving to New England after your husband's discharge, emissions inspections and rules are much tighter there. Hence, another good reason to spend the extra $$ for a California certified cat con. Some of the New England states also require the use of CARB certified/register cat convertors as well.
That hasn't cleared codes since at least '96 model year. You'll need a scan tool or code-reader to clear the codes.Gonna clear them via unhooking the bat
Evap system is often a failed (or loose) gas cap. Can be lots of other stuff, but often the cap.In case anyone was wondering, the codes that came up were P0442 (EVAP system small leak detected)... probably from me not tightening down something all the way even though it was as tight as I could get it... Other code was P0172 (System Too Rich Bank 1)
