Secondary Transmission Filter Installed (Feedback)

[2000co]

I replaced the filter yesterday and the fill-up process is the worse idea Ford had so far. I'm going to buy a pan with dipstick.

What's the torque for the torx bolt in the drain plug? The Haynes manual is useless.

This is a great idea, everybody should do it.
I've yet to do it on the Explorer but my BMW road car had it.

People are saying that they get an improvement in transmission performance, surely you'd get the same benefit from a fluid change? Temporarily.

It's just I've never heard anyone say how much their shift has improved after a fluid change unless the change was actually to correct a problem.

Secondary Transmission Filter install

I am worried that my 5R55W isn't supplying transmission fluid through my cooler.
I installed a secondary transmission filter the other day in line with the transmission cooler. I wasn't sure which cooler line was pressure and which was return, so I removed the hoses from the cooler and put the each of the lines in empty 2L coke bottles. I started the truck, put in gear with the breaks on. I revved it up for about 30 seconds in Drive. I only got a tiny bit of fluid in one. I wasn't convinced that it was the fluid from the feed or just old fluid from the lines, so I emptied that bottle and tried again. The next time I got no fluid at all out of either hose. I tried a couple more times with the engine in gear and me revving the engine. Still nothing!
The engine was cold. Now I am wondering if the fluid is suppose to always flow through the cooler or if the engine/transmission has to be hot first for that to happen. It is also worth mentioning that the truck is not level when I did this. The front side of the truck was jacked up. Would that matter?
I took the truck for a 20 minutes drive today. The transmission temperature at the secondary filter adapter only moved up to about 145 degrees. 5 degrees higher than when the gauge is at it's lowest point. Should it run hotter? Is it showing that the temperature is cool only because there is no hot tranny fluid going through the secondary filter device?

Does anyone have some advise for me? I don't want my transmission to go Chernobyl on me.

A couple things...

Your 5r55W trans has a cooler bypass valve in the transmission. That means until the transmission is up to temp you won't get fluid into the cooler. This keeps the trans from over cooling..

Next, you do need to figure out which is the out and which is the in on those cooler lines. I know its been posted on EF before but I don't see it right now..

Once you have that you just need to make sure you get the output of the trans to the input of the filter.. If you get it backwards you will block the fluid from getting into the cooler.. Not good once its warmed up..

As for temps. I like to watch the temp of the fluid in the pan.. Thats the fluid that the transmission is going to use. If you measure it on the cooler (or on the way to the cooler) your reading output temps and in your case you don't get an output unless the trans is warmed up.. So, in your case. the Pan is really the only good option for a temp sender.

Secondary Transmission Filter install - Cooler lines

Thanks for the help. I see now that I will only start getting a reading once the transmission is warmed up. I never want to have to take that transmission pan off again, so I will just stick with the current configuration. At least I have an idea of how hot the transmission can get now. I had a hard time trying to find which cooler line was the return and which was the output. Until today:​

One last question... I lost about a half quart of transmission fluid when I installed the filter. The filter also hold some transmission fluid and I would like to compinsate for that. Can I just use the return line to push more fluid back into the tranny?

It's possible to feed the fluid into the return line since it's going into the transmission.

Trans Cooler

Hi guys

what kind of liquid is inside the trans cooler , is it the same coolant of the radiator or different all together , is there a trans cooler for the Explorer 2006
& where is exactly

 

[Hank]

Transmission fluid.

 

[xwasif]

trans cooler

how then do you cool the transmission fluid , when the fluid is passing through the trans cooler, how is it cooled down or just by passing through the cooler it cools down by air . where is it located exactly :exp::exp::exp:

 

[Hank]

It sits in front of the radiator and the fluid is cooled by the air passing through it.

 

[Maniak]

The transmission fluid on the automatic at the least goes from the Transmission to the Radiator. In the Radiator is a heat exchanger. Basically its a tube that runs within the tank on the radiator. That tube is surrounded by the engine coolant.

So, the Air passing through the radiator cools the coolant and the coolant then absorbs or adds heat to the transmission fluid (depending on which is hotter).

An Aux transmission cooler is normally placed in front of the radiator and a/c condensor and works more like the radiator does with coolant. Basically, the aux cooler is a small radiator looking thing that is full of transmission fluid. As air passes over it, the heat is pulled from the fluid just like how the radiator pulls it from the coolant.

Did anyone installed Magnefine filter in 2005 Mountianeer with 5r55s tranny?

Per Magnefine I need to install the filter after the tranny cooler in the return line. Which line is the return line in my truck (top or bottom line)?
I also notice that the rubber hose section on the cooler line is very short. Is it okay to connect a new rubber hose and loop up, add the filter and loop it back? Or is it better to cut the steel line and add the filter?

Secondary Cooler OEM?

Some generation Explorer left the factory with the secondary cooler?
Reason for question. A friend often claimed that the 1998 Ford Explorer Limited 5.0 V8 (Transmission 4R70W), was made with a oem cooler.

 

[albi1cnobi1]

Yes, some did. My 99 SOHC V6 with the 5R55E has the factory aux tranny cooler.

External Cooler

So basiclly the transmission oil will pass through both radiator & external cooler then back to the transmission , or its just the external cooler & it has nothing to do with the main radiator ???

 

[albi1cnobi1]

That's correct, the fluid passes through both the radiator and the aux cooler before heading back to the trans.

 

[Orleans]

Yes, some did. My 99 SOHC V6 with the 5R55E has the factory aux tranny cooler.

What is the location of the secondary cooler oem?

 

[albi1cnobi1]

In front of the radiator, behind the grille.

 

[SwaintaN]

This is where mine was, i no longer have the ex, but those i still have, ha, i need to get rid of them, but #2 was aftermarket, it was the final cooler before tranny.

It's been 11 years since I installed the trans filter setup on my F-150.
Still works well.
Total of about 126,000 kms. Replaced filter twice, plus the original one that went on when I first installed it.
Probably due again soon, although each filter has looked pretty good when I have cut them open.
