Inline Transmission Filter
Hi all!
So when my replacement transmission was installed 75k ago, they installed an inline transmission filter on the return line to the tranny...
The part # is XC3Z-7B155-BA. I have searched around and aparantly there is no aftermarket replacement? A motorcraft replacement is about $100. After going to the parts store (Checkers) they came up with 2 part #'s for this...FT-167, and FT-116. I also found a third part# which I can't remember...these all vary in price from $19 to $80...
Have any of y'all found a suitable replacement. I am wanting to change this out since my transmission is shifting a little funny as the temps continue to rise around here.
BTW...my local dealer did a fluid swap when I took it in last year for what seemed to be a transmission issue (jerking in overdrive), but ended up being a Coil. Due to the condition (grime) of the filter, I don't believe they changed it. They did find broken snap rings, and changed valve *****.
Your help is appreciated!
Regards!

Ok! So after a little research, I found that that filter is made by Magnafine...
It can be purchased from their site for $ 16.00 or, I found it at a local Napa Auto Parts for $ 26.00. The Napa part# is 1-8514. It was a 5 minute replacement.

Here is a bunch more info on Magnefines from when I tested them a couple of years back.
Ignore the arrows, which point to the o-ring on the cap. The magnet is at the top, with the flow director below followed by the filter element. The bypass is built into the nose of the element, just under the flow director.
The Magnefine was qualified by Ford in the '90s as an addition to reman trans kits because they were having so many comebacks due to failure debris being left in the coolers and lines by inadequate flushing. There was some talk about installing the filters on cars but the bean counters, and others, killed it due to cost and complexity issues. I have them installed on everything I own and they also make a great power steering filter (a system which has no filter at all. I did some testing on the Magnefine and below are the results.
The Magnefine reduced the ISO cleanliness code of the oil in the trans of my '05 F150HD from a already clean 15/14/12 (it was a fairly fresh change right after I bought it with 7K miles) to 13/12/9. That's an 81 percent reduction in the contamination levels in 2200 miles. For a frame of reference, in the newer transmissions, Ford likes to see about 18/15 max. Not sure if there was a spec back in our day, but the general rule for vane type pumps and hydraulic valves is about 16/13.
Sorry to change from three digit to two digit ISO codes on you. You can google "ISO cleanliness code" to get details but, roughly, eliminate the middle number and you have translated a three to a two digit code. A drop of one code number is about a 50 percent reduction in particles.
On the Power steering of my F150, the Magnefine reduced the ISO code from from a dirty 20/17/12 to a clean 17/15/12 in 552 miles. I haven't retested the PS in a couple of years but I did spot check the trans and it's holding at 13/11/9 after about 15K miles. Interestingly, I tested new oil at the time and it was at 16/15/13, so my oil now, after 15K miles is cleaner than the new oil I installed.
According to John Eleftherakis and Abe Khalil, who have done a series of studies for the OE trans manufacturers and the aftermarket that started in the late '80s, and continue to today, 75 percent of the harmful debris generated in an automatic over it's life comes from the manufacturing process and from break in. After sampling the oil in thousands of automatics in service, they found that the average trans with 70K or more miles that has not had a service contains approximately 263 mg/l (milligrams per liter) of contaminants, 90 percent of which is metallic. Of those metallic particles, 51 percent are ferrous (iron/steel), 21 percent copper, 11 percent aluminum and 7 percent lead. The particles range in size from 5 to 80 microns, about 82 percent of them larger than 5 microns. Yes the trans has a filter, but the best pan on the market today filters at 80 microns nominal and many cheap ones, or older filters are at 100 microns, or larger. Some of the screens in older transmissions are 150-200 microns and all they get are the "boulders.
I checked with SPX/Filtran, the company that makes the pan filters for Ford and found the F150s from my era used one of the better 80 micron filters. A generic replacement you buy in an auto parts store may NOT be as efficient. It might be, but don't count on it unless it's a reboxed Filtran fitler, which some are (don't ask me which, just open the box and look for "SPX/Filtran" or "Filtran" stamped on the filter)
The Magnefine contains a 35 micron cellulose filter and a very strong magnet. It also has a bypass valve, so even if the filter plugs, it will flow 100 percent of cooler flow. A 35 micron filter is about the same as an average oil filter, but since 51 percent of the metallic contaminants are ferrous (iron), and the magnet can catch virtually all of those (it has a nifty flow director to help with that), the net efficiency is a little higher than the the fitler alone would indicate.
