welp, I'm doing it. I guess no bypass no chance at large particles in clutch packs, and since transmision oil is thin, kinda makes sense. But, I could see why some guys have issues in the cold. So I'm putting the synthetic with bypass on my truck, this summer anyhow, maybe end of summer.

I mean consider this, how many years did my filter have no flow through media because the media was stiffened?

So here’s the video of the cut open OEM trans Spin on filter next to a mobile one of the same size.

Pardon my crappy video taking skills and my blabbering. I think I said the word “flow” about 35 times[emoji23][emoji23].

So the OEM spin on filter has no bypass valve. But the way the anti-drain back valve works seems to me that there is no way there could be a lot of pressure or it would close up the hole in the top of the cartridge. Take a look and see what you tink.

Dude, you did a great job with that video.

The OEM trans filter really is an odd design. So if I'm understanding that right, when the fluid goes through the media it has to push that valve up to come back through the center tube?

Forgot to add a picture of the bottom of each filter to show that there is not even a hole in the bottom of the cartridge for a bypass

holy smoke, lol. thanks for pointing that out.

If what corey says it true, the flow goes through sump filter first, then spin on filter, there really is little chance of something getting stuck in clutch packs even if the bypass opens imo. I'd litterally be happy if it was just the sump, because that thing is solid.

Yes sir.

After the oil passes through the media the only place for it to go is up through the center tube and has to push that plate up to pass it.

It literally works the same as anti-drain back valve but instead of it being before the oil goes through the media like we are used to it is after it goes through the media

So it basically forces the fluid to go through the media...

U&A: Thank you for taking the time to create the video! :favorites13:
I personally see the replacement of the OEM spin -on with a much higher quality synthetic media filter nothing but a Win/Win for us!

Now: How long are we gonna leave these synthetic (wire backed) media filters in service?
What do you all believe is the max service life?

The ATF sump & fluid is a much friendlier environment compared to the oil pan & oil.

I’d be ok with 60,000 miles.

Kyle thanks for taking the time to make that video.

Is a case of Trans fluid enough? Pan swap and filter swap, I’ll probably only have about an hour or 1+30 to let it drain as I can only rent the lift for a couple hours.

Or would y’all suggest the pump?

Just my opinion but I would not hesitate whatsoever to be fairly quick about it if needed. You’re still going to get a solid 6 1/2 quarts out. Even if you let it sit overnight you might get a maximum of an extra 1 quart im guessing. Probably more like half a quart.

Now if i was planning 30,000 mile intervals or something along that line I would want to get as much out as possible.

Well that will save me money renting the lift! So a case is more than enough to start, with a couple drain and refills to get all the stock fluid out and replaced with better stuff

Since you're changing the filters quite a bit more fluid comes out, especially on the sump filter. Definitely be ready for that lol. Anyways I would let it drip for 25-30 mins and then do your filters. Like Kyle said, probably a good solid 6.5 qts out with the filter change.

I'd have 7 or 8 qts on hand just in case....

The ATF sump & fluid is a much friendlier environment compared to the oil pan & oil.

I just left my oem on for 8 years, bad idea, but I could see leaving the RP for 8 years with so few miles. If I was driving 10k miles a year, I could see like Jeff says 60k miles. I think that is a sweet spot, good time for a pan drop anyhow, get some good fluid and check the pan for metal.

Good news, if you are lazy and just want to do fluid, you can, because imo that is the most important thing now. new fluid as often as you can.

Dang, I forgot about my pump, but I have to get that paper filter off there this summer. Maybe I will just pump a gallon out for time to time for the next decade. Now that I got Kyle's freaking killer thread, and I will have a great filter, I can concentrate on fluid. I don't need to upgrade pan at this time for my use. Maybe someday.

thanks again to Kyle for taking another random chance to find the perfect thread for all of us. Mind you he first followed corey with an over priced version, then followed me with a loose fitting one, and finally landed the perfect thread. Thanks for Corey for finding this as well. It takes a while but we do figure **** out, but this particular thing took many orders to figure out, and one dude did that. I wouldn't have taken a chance again, but very glad he did. This latest version PERFECT,

Yep, y’all have surely set me in the right direction, even if I’m the only ******* still running Amsoil! LoL.

So I guess it’s my turn to order everyone a **** ton of filters?

common jeff, those days are over. Amsoil is good stuff, especially their tranny and diff fluids. And they took m1 who had the best lspi formula and boosted moly, way good. Amsoil is a valid choice for sure, and more RF members use it then redline.

I know! That’s why I laughed, I know you guys are good, as long as it’s working, keep doing it! The Durango seems to really like the 4qts of 5W-30 and 3qts of 0W-40 Amsoil SS, so I’ll run it for another 7500 miles and see what the analysis says.

Ok,

I asked Mike for that picture he took a while ago when he cut open his spin on transmission filter. My head was tinkin sometin fishy was going on. Check out the differences between the filter I examined and the one Mike took apart.

This right here is hook line and sinker in my opinion that we should have no worries about running an engine oil filter. The one I examined we all see is a bit different and raises some questions .....but if Mike was to buy a new filter for his trans it would look identical to mine. But look at the one Mike took out ...it is literally an engine oil filter and here’s why.

So here’s a picture of Mikes filter. You can see a few important things here.. look at his anti-drain back valve. It is actually the same thing as a traditional engine oil filter. Now look where he cut the filter open and you can see the center tube. you can actually see through the holes at the top of the cartridge so there is no goofy spraying and plate anti-drain back like in the one I examined.

Now look at mine and see how you would never be able to see through the holes in the center tube if you cut the media off. c7cda0d9fe0e4852562b21dd8b2ef98a.jpg

And look at the seal that i have in place of Mikes Normal anti-drain back vlave

So,

Mike has been literally running a paper engine oil filter with no bypass.

We are all good. IMO
