On the connection of the cooler line to the radiator I used the transmission connector for 3/8"
There's several versions of this brass connector or adapter - I mean different companies selling what appears to be the same precise coupler. The male flare clicks into the e-clip quick connector at the radiator. Then I used a fuel injector clamp and an expensive Swedish ABA hose clamp (stronger with no damage to the rubber Gates transmission hose line).
Then I got the OEM Australian made Magnefine filter - this is only sold through ebay from what I can tell. I think I got the last one for 3/8" OEM Australian!! No longer can find any more on ebay. It may be still stocked through through other companies but do NOT believe the NAPA advertisement - the photo shows the OEM "made in Australia" Magnefine filter but in fact it's a rip-off filter made in China. The OEM Australian Magnefine is no longer produced - it has its own special patent design that separates the magnet from the paper filter. So the magnet attracts metal fine particles on BOTH sides of the magnet and the magnet is also bigger. Also the plastic case is stronger and doesn't crack in the cold - while the China rip off case also does not have a good overflow valve on it either.
I don't think mine has a screw off top to it. I think the later versions no longer screw off.
The Magnefine Filters System by Boss Products was revolutionary when first produced at Boss Products facility in Sydney. As soon as they were then launched in the US, companies like Ford and Daimler Chrysler used them as OEM parts for their magnetic filtration products. And you can understand why. The MAGNEFINE filter extends the filtration spectrum to provide dual filtration. It is designed in such a way as to be completely effective in removing up to 95% of damaging ferrous metal particles from automatic transmissions and power steering systems.
any junk that gets into the fluid from inside the transmission workings will have to pass through the cooler(s) before flowing through the in-pan filter. From this flow pattern, one can understand how junk can become built up inside the cooler. I had read someplace that MOST, but not all fluid flows through the cooler(s). The thought process in placing the Magnefine, or other cooler line filter in the RETURN line from the transmission is so that any junk that may be in the cooler will be caught in the filter before returning to the transmission pan.
The filter top simply unscrews, and is sealed with an O-ring. Large slip-joint pliers or pipe-wrench will work, but may damage the filter. I am uncertain if the filter can be safely reassembled, without leaking, as I have not yet done that. ...The first defective filter was removed after service of 1-year and 7800 miles. It was leaking from the seal on the screw-on top, and had a defective by-pass valve. The fluid leakage was minor, and not obvious until the wheel-well liner was removed. The box says NAPA, the filter label says Raybestos/ MagneFine... i discovered that there is a leak, at threaded connection , under the Magnefine sticker....I had the plastic ones bought directly from Magnefine with no issues over many years with various cars. As I understand it, a big part of the "leaking" issue was cheap Chinese knockoffs....Over time, we had a volvo recover from 1-2 shift flare after installing a magnefine at 105,000 miles. Yes I have had the plastic ones weep fluid but never "leak."... the Magnefine's as they might stick half way and cause restricted flows and higher heat. That happened to mine and when they took it off and cut it open, the valve that is supposed to open to bypass the filter when it gets too clogged, failed and only opened 1/2 way. The filter wasn't clogged, in fact there was no material on the filter at all...The Raybestos filter APPEARS similar to the Magnefine, but I have taken apart both types apart, and here are some of the differences...
1. The bypass mechanism is entirely different. The design, where it seals, the length of spring, the way it opens, how the fluid bypass flows... entirely different.
So that leaking was from the China rip-off Magnefine by Raybestos! I used just one fuel injector clamp on each side of the magnetic filter itself since the pressure on the filter is not as great. I did tighten this stronger - hold not TOO strong that the plastic holds without crushing...
The end nipples (the parts that are deformed in the Raybestos knock off in the op) differ in shape and barb profile...The ends collapsed and crimped closed when the hose clamp was tightened. Almost burned out my transmission! Glad I was paying attention. And, No, they were not overtightened. I can literally pinch the ends closed between my thumb and index finger, without straining. Garbage!... The plastic housings are not the same flexible plastic as the real Australian made Magnefine filter. The knockoffs can and do can shatter....the new filter split dumping out all the power steering fluids. Figuring this was just a defective unit I ordered another and the same thing happened within 2 days. If you live in a climate where extremely cold weather is not an issue this is an outstanding product. If you need to operate sub zero for even a brief time be ware.
I can see the filter so I will keep an eye on it for any leaking. So far it has been fine but I just tightened the clamps even tighter!
Apparently Magnefine replaced the old plastic ones with the new metal ones due to counterfeiters and the possibility of cracking the tubes when overcranking hose clamps.
Ford used to have major trouble with remains failing due to contamination due to built in dirt from the reman process combined with failure junk and in the '90s instituted the return line filter program that, according to my reliable sources, dropped the failure rate from significant double digits to low single digits.... reman tranny will generate 75 percent of it's lifetime total of contaminants in the first 5000 miles. Those contaminants include built in dirt from machining and assembly (variable according to the cleanliness of the assembly facility and that can be from great to appalling) and break-in material, which is unavoidable. If you change the oil and pan fitler within 5K miles, you eliminate those contaminants but that's kind of a waste of oil. An inline filter will do the same thing for the most part without wasting the oil. You place this filter on the return cooler line.
this filter is as you found out installed after either a tranny failure or rebuild and is typically installed after the stock coolers. The reason is after a failure debris will get lodged in the cooling lines and especially in the two tranny coolers and unless all the lines and both the coolers (one is internal to the radiator and basically requires the radiator to be replaced) are replaced you can NEVER FLUSH all the debris out so as a cost saving measure FORD installs it for added protection. They found failure to do this resulted in redundant tranny failures from contaminated coolers in short order.
it collects is just as much as you normally see on the magnetic tranny pan drain plugs. I put mine on before anything happened at around 20K miles from new
They stopped doing the line filter on reman units because people wouldn't replace them. Then the in line filter clogs and there is no flow to the trans and the trans go boom.
I have a brand new magnefine filter, with a metal case instead of a plastic one, but it is NOTHING like this inside. I can see through both ends and the only thing I see is a metal screen in the middle of the filter
The first time I opened a Magnefine that had been running on my 4R100 tranny, it contained about a tablespoonful of mud around the magnet. That mud was extremely-fine magnetic dust mixed with ATF.
5 OEM Magnefine ATF filters have not leaked after totaling 85,000 miles. I have them wrapped in a thick rubber hose lining for protection and tied down with heavy duty zip ties. Rubbing against things or vibration might lead to problems like leaking and the key is properly insulating and securing the filter.
the sticking bypass, the leaky o-ring seal, the brittle nipples, the brittle housing, the overrun glue, and all the other problems... only found on the cheaper rebranded knockoffs sold by Raybestos?
One of the Wix (Filtran) started leaking at the seam. Almost pumped out all of the transmission fluid. If you take them apart, the Magnefine has way bigger magnets than the Filtran. I had no problems with the ribbed Magnefine. After the assembly seam split on the Wix (Filtran), I'm not sure I want to trust them again. These Chinese Raybestos filters can fail (leak or the cap breaks off), and destroy your transmission from low ATF.
I understand that the current MagneFine filter top is glued (as well as screwed on with threads)...Over the last 9 months [in 2013] we have been inundated with reports from customers that the MagneFine filter is failing or leaking between the cap and the body seam. In 99% of cases it has been the knock off filter that the customer has and not a MagneFine filter.
Then I ran about a foot and half of Gates hose back up to the metal cooler line that returns back to the transmission. This previously had a compression connection on the metal line that I removed - with a quick connector e-clip into the metal line male flare. So I then got a 9/16 female UNF with a 3/8" barb for the rubber hose - the hose end has to be cut straight and pushed on all the way. There's only one company that sells this connector - it is Dixon - and then there is an OEM ACDELCO 9/16 male to 3/8" quick connect for the transmission line. The Dorman aftermarket does not have as good of a quick connect e-clip design according to the reviews - more of a gap - so I wanted to make sure to use the OEM quick connect design for the e-clip. The Dorman is sold in the autoparts stores so you have to look for the GM oem part directly. GM OEM Transmission Oil Cooler-Inlet pipe connector 15226661
I got e-clips with rubber o-rings - as a set - this is sold from one company also - and then I put a rubber o-ring into the brass Dixon 9/16" female UNF that was then tightened into the male 9/16 on the ACDelco quick connect. I used TWO of the expensive Swedish ABA clamps (these are $8 each at West Marine but you can buy them in bulk online). I bought them in person and I bought three of those clamps.
All pressed worm gear housing increases the strength of the clamp by 30%. 9 mm band width. Product information. Manufacturer, Scandvik. Model, ABA
The Ford "rebuilt kit" Magnefine filter - uses a similar barb to female brass connector!!
They slapped the Ford brand onto the Magnefine filter....
It turned out to be a bad trans cooler bypass valve,
You have made a good decision to install a Magnefine. You are up there with the best transmission guys in the USA,the top transmission engineers at Ford and Chrysler who spent years and years and hundreds of thousands of dollars testing an proving the effectiveness of Magnefine in countless field tests and in the Ford labs.
Their conclusion....wow this little sucker really works. They did tests to show that repeat transmission failures dropped to zero once the Magnefine was installed.....
You should not have any problems with a Magnefine on you RETURN cooler line with the flow direction toward the Transmission.
Ford and Daimler Chrysler use our filters on all reman trannies to stop 2nd failures, they operate to ISO standards and our filters are OEM approved.
The bypass within the filter will kick in at 5psi.
And it will reduce the flow - say from 10 gallons per minute to about 9.5 gallons per minute. so just a small amount. But well worth it to keep the fluid very Clean! Just change the fluid filters every 10,000 miles
I might have to do that - put in the 1/2" - maybe I bought the 1/2" by mistake anyway? hmmm
I've noticed now that that last time I did a drain and fill there was pretty much nothing on the factory magnet. Not sure if it's because the magnefine is catching more of the magnetic particles
