See this current thread and then tell me I'm not on to something here:

Maybe, maybe not. But it's one less variable to worry about with good filtering in place.

 

Fuel? Because even Dodge themselves developed a new filter after the original one was not filtering as well as it should. Also due to folks such as Don M who take the time to post photos, do research, and take the time to explain to us why x or y injector had issues. From what I've seen, quite a few tend to be fuel contaminants be it sediment or water.

Water? Because people over 5-600 hp are having pressurization issues. Hardly an issue at stock levels.

Engine oil? Ya got me. I think people do it because the 04.5+ with the third injection event uses the combustion chamber for EGR and the oil gets dirty after the first crank.

I personally see very little benefit to the bypass filter, but you and others do. If you do, and decide to put one in, then that is your perogative and at the very least I can't see it hurting anything. Good luck with the set-ups, and enjoy

 

Basic principle #1: Any automotive system using fluids, oils, water, whatever is subject to contamination and degradation of those fluids. Even brake hydraulics that basically just sit there compressing calipers and doing little else are liable to fail at some point due to lack of maintenance.

There are two ways maintenance is addressed. 1) Changing the fluid at specified intervals, 2) and/or filtering the fluid during use/service.

Basic principle #2: Various mechanical breakdown are commonly attributed to failure of the maintenance systems (changing and/or filtering) due to either human and/or systemic deficiency.

Just wanted to make sure everyone understands the basic principles.

Now, if you actually believe Dodge or any other manufacturer has a primary goal of optimizing the maintenance systems to reliably support anything more than the warranty period, then I have a bridge to sell you!

Because too many failures were attributed to ineffective filtration before the warranty was up.

What about filtration? OTR trucks and all sorts of heavy equipment filter the coolant. Why not consumer pickups? Because that would be an added unnecessary manufacturing cost when the cooling systems can make it out of warranty without it. With new long-life coolants, even with no maintenance at all. Ever look inside the radiator of a vehicle that hasn't been opened in five years?

Have you ever used one? I guess some of you people just don't realize you are not getting away with simply dismissing this based on your personal beliefs or hearsay. Bring some facts to the debate.

 

Ok, thanks for bringing some facts to the debate I fall under your category of doing maintenance at scheduled interviews. After seeing the mileage threads people post where they're reaching 3-400k+ miles doing regular maintenance, that's enough factual info for me to keep my truck the way it is and do any and all maintenance at or before scheduled interviews.

 

So now go back some specific time period and support your theory by counting threads posted where somebody is running 300+k miles doing regular maintenence with no problems. Then go back the same time period and count the number of threads where someone is posting about this or that problem they had. Take just transmissions to narrow it down even further.

Get back to us after you have the numbers. Good luck with this delusion, and enjoy!

 

Actually, you would need to show how many failures were due to under filtered oil......not all failures.....hard to prove or disprove..........so who is deluded? Start counting Ace.

 

...continuing on from Annabelle. How many were abused? How many towed over GVWR? How many were used with added power? How many of them actually had followed the recommended service interval? I would say a safe estimate of what failed due to filtration issues is probably less than 10%, and of that 10% a lot of those were probably past their recommended service interval.

Again, no facts there though. Just pure speculation with a little bit of educated thinking.

 

Or by the same token you would need to show how many weren't. You'll find the majority are directly or indirectly related to fluid contamination or breakdown. When something begins to wear out or breaks, you have more and more debris cirulating in the fluid, filter begins to clog, heat builds and next thing you know, it's game over. The whole trans is trashed. Pretty typical. Ask Dozer, he's seen it many times over the years!

Have you you been reading the forums much over the years?

 

Thanks for making a good point for me toy! Which tranny do you think will hold up better or longer under excess stress or abuse - the one with dirty fluid or the one with clean fluid? Do you think the normal service interval would result in damage sooner or later, depending on the condition of the oil when the service is stretched out further than it should be because the operator fogot to get the service done?

No matter which way you slice it, whether you decide to do the actual research to disprove your own delusion or not, you will find the amount of discussion on these forums about trucks that last a half a million miles is a drop in the bucket compared the discussions about problem transmssions. I'll even conceded some low percentage of those problems directly or indirectly related to ATF issues stiff far exceeds the rosy half million mile regular service picture you would like to paint.

Thanks for helping prove my point! It's been fun playing the straw man for all you filter skeptics out there. I can't figure out why the moderators haven't locked this thread. In any case, I'm done with it now, got better things to do. Gotta figure out how I'm going to do the coolant filter, and whether or not I'll even bother posting a writeup about it. I suppose it's not really worth it.

 

Please, don't take my criticism as me not caring about what you did. I give you props for the idea, and without folks that do write ups and experiment such as you, we wouldn't have some of the innovations we do have. I could comment about a few things in your last response, but something about letting sleeping dogs lie or however that phrase goes comes to mind.

Oh, and I assume it hasn't been locked because for the most part it's been a pretty decent discussion. I look forward to butting heads with you over the coolant filter soon Although, that seems like it wouldn't be a bad idea at all.

Just wondering.....if the stock filter will filter at 100% up to normal drain interval, what is the bypass filtering? Also will the bypass filter the fluid in a timely manner, without allowing the tranny to grenade due to contaminated fluid, should the stock filter fail? Just playing devil advocate here.......nothing personal.

 

Not my hypothesis to prove or disprove........it's yours.........however, I don't know how you could prove it. Interesting to ponder though.
