Happy fluid = happy transmission. The more you filter it the more miles you get out of the fluid. Very simple math.

I do. It's very important to the life of your oil, and the life of your machine. Why does everybody recommend using OEM filters for this product? Because the off brands don't filter as well. Get yourself a 40 micron fuel filter and see how long your injectors last...

There are efficiency ratings also. Micron ratings aren't absolute. Toilet paper style filters are more efficient at trapping fine particles than pleated element filters...

You can't tell by looking. You're still missing the point, there is full filtration and there is bypass filtration. If you don't understand the difference I can't continue this discussion with you. That's like saying "my truck is better than your car, just look how big it is". They are meant for different jobs.

Just because the pan filter gets 100% of the fluid doesn't mean it's better at trapping dirt, it just does it in bulk. In the same way a bypass filter isn't better because it catches smaller particles, because it doesn't catch the whole flow. You have to use both to get the best benefit. I'm not saying either filter is "better" alone.

It's like owning both a car and a truck. Some people only own a car and they can't haul anything big. Some people only have a truck, and they can't get great gas mileage. If you own both you can get the best of both worlds. It might cost a little more, but not everybody is in the poor house.

If you aren't interested in making your truck better that's fine, but no reason to complain about anybody that is. You might as well stop using good filters and synthetic oil in anything. It's ridiculous for you to get upset about using two filters and then suggest using Amsoil. The idea of both is to make the fluid, and the device it's inside of last longer.

Lets be honest, if you leave the inline filter, you might stand to gain something, you might not, but it's not going to hurt you. What do you have to gain by getting rid of it? You save $18 on a filter? If you're that cheap you shouldn't be driving a diesel truck.

 

I don't really think a person can say that either one is "best" for ALL situations. The only thing that could be best is both together. You can show situations where the bypass does better, and you can show situations where the full flow does better. They both will allow some portion of the particles to keep circulating, in a different way.

Another thought is that the stock bypass filter is nearly off below 165 degrees, and if your truck isn't loaded heavily, you will usually run cooler than that. Maybe no filtering at all is needed until they start working hard and it's only then that they get hot. A lot of other automatic transmissions barely have a filter at all, it's almost like a window screen. When you really start working hard, is when you create the most particles that need to be cleaned out.

That's what's great about bypass filters. Since they never see the full flow, it's ok if they clog up, especially if you also had the in pan filter to back it up. Once it's full the bypass circuit just stops flowing and the main flow continues around. Frequently people that use them on their engine will have pressure gauges on both sides of the filter so they know when to change it.

 

I've had both filters in my hand, and I can see which one is better.

I'm not arguing at all, just trying to help based on what I have seen and experienced, not necessarily what I read on the Internet.

Have a great day!

 

I'm not trying to argue either. It's just not something you can see. It's not that simple.

That's like saying "I had two bottles of oil in my hand, and I could see which brand is better. One was in a quart bottle, the other in a gallon bottle, so the bigger bottle must be better."

I really wish I could measure filter micron and efficiency ratings with my eyes, that would be REALLY cool! I also wish I could have xray vision and a llama that poops gold coins.

 

Obviously you haven't held both filters in your hand. The stock has a screen, the FT-180 has a pleated filter media. The visual difference is like looking at a bald tire vs. a new tire....no lab testing or special measuring tools needed.

 

The screen goes in combination with the bypass filter installed in the cooler line. That is what we are talking about here.

You bring up an important point though. Even without the full flow pan filter, your full flow is still being sent through a screen.

Edit:
This is the filter we're talking about. You can see it literally looks like half a roll of toilet paper. For less than $20 it even comes with the o-ring.

We question the OEM thermostat because we can prove they dont work right. People have trouble with them.( because they don't hold temp.) I dont think anyone has proven that the external trans filter doesn't work right.

 

I never knew who manufactured either filter.

I don't think that is accurate. I know Ford recommended it with a 4R100 overhaul, but I think, I'm not certain, that they dropped that requirement before the TorqShift was introduced.

Maybe, maybe not. If it could remove the fine particles as well as the OEM filter, then yes, you would be fine. If it allowed a larger particle to pass, then I expect you would have problems.

 

I have seen trucks where this was done from dealerships Mark, but I don't know that it was a Ford procedure. IIRC it was on trucks that had the "snap ring" problem in the transmission case, but that may be inaccurate.

 

Tim / Mark - Check the WSM on the repair process regarding the addition of the in-line filter. You will find it in section 307-01. The in-line filter number is 2W4Z-7B155-AA.

Specifically the Ford Procedure verbiage is as follows:

"If installing a new or a Ford-authorized remanufactured transmission, install the in-line transmission fluid filter that is supplied."

The manual does acknowledge (in the same section) that some overhauls may have been done to include the in-line filter and some may have not. HOWEVER - Ford goes on to say that if it did NOT have one, then install one .... and if it DID have one, then to replace it.

edit:
It is on page 307-01-150 in the 2006 manual - pretty specific

 

I can't believe that a whole group of forum members that I and others here have such a high regard for, will actually allow yourselves to be drawn down to his level. It's an argumentative one and absolutely nothing but that.

Someone the high school debate team kicked off and has never gotten over it, so they use terms like "it's very simple math" yet they have no math, where others have. They use terms like prove it to me, yet they can't prove their own, completely and purely argumentative approach and logic.

Really?! It is really simple. You take the user name and say: don't show me any more of his nimrod posts, and then you won't see them.

Because they are nimrod and only argument loving. I've stayed out of this because it really was just so stupid. But I would really hate not saying something and losing some people I really admire and opinions I respect because of some idiot that is arguing an nth of a point that is beyond ridiculous and just loving it.

And yeah, it does make a difference to me when the engineer that designed my transmission is on a forum and gives a crap to contribute REAL information. Versus have the guy that flunked debate team bring up nothing but bunk.

Troll: go screw with some other forum on some other nano-particle of argument you so seem hell bent to get off on.

Mods: shut this thing down before we lose some good people...

 

You sir have a serious attitude problem. You are the only one in this entire thread that has been so childish as to start name calling. And you have offered no information of value here. If you have a problem with sharing information you should not be on this forum.

Mark readily admits that he did not design the filters.

 

Thank you for the sir. I deserve it. I brought up this filter and pan change years before you were here. Childish? Name calling? Did I name you?

We lose great people on forums like this because of people that berate them using language, school-yard like, condescending, disrespectful, argumentative for no real reason, like you do. And I won't say sir as I don't see you in my line of command or in any way garnering my respect.

Take it as personally as you want.

 

I think this thread has run the course, as an owner it is up to you to make a decision on what is best for your vehicle.
