Here is a TCI AOD Pressure Test on their Streetfighter AOD Transmission. TCI states that these pressure readings provide a valuable source of information when troubleshooting transmission problems or as a system check after rebuilding a transmission or installing a TCI valve body.
Good point, it looks like it was at the test port. I have never ran my truck with a transmission cooling line disconnected, largely because I use expensive Amsoil Synthetic ATF and have no need to do so. Keep in mind there is a difference between volume and pressure and an open line with no resistance may not allow pressure to build, especially at higher rpm. I still choose to use a "Hydraulic" specific filter as recommended. According to TCI:Ok, Very well.
But just for the sake of I'm curious. Where were those pressure readings taken? The cooling line or test port? The two have vastly different pressures. I don't doubt that a upgraded transmission may have a higher cooling circuit pressure, but a stock transmission cooling circuit isn't anywhere near that much pressure, It would blow a plastic magnefine filter to bits if it were. Besides, you can start a vehicle with one line disconnected and it will come out in a gentle stream, If it had that much pressure I doubt that would be possible.
Transmission Line Pressure SpecificationsThese readings can be obtained by attaching a 300 psi fluid pressure gauge to the appropriate pressure port on the transmission, and running the engine at 2000 rpm.
Whatever works for you. I just read those pressures and was shure I've never seen cooling circuit pressures that high. Now main line and test port pressures will hit that all day long.Good point, it looks like it was at the test port.

pfun41, it looks like you are correct.I just read those pressures and was shure I've never seen cooling circuit pressures that high. Now main line and test port pressures will hit that all day long.
yo Seattle,I am curious about this Ford OASIS (Online Automotive Service Information System) message that I believe that is referring to the Ford rebranded Magnafine Filter?
Can you find any OASIS for 96 Broncos or prior years that reflects same?
It has been brought to our attention that there is some issues with the MagneFine In line Filter. In reply to any issue that you find I would like to advise that we warranty the product for its operation and performance.
I would also like to advise that there is a Knock Off in line filter that looks exactly like the MagneFine. This copy is Made in China and is sold on line and in some the same traditional distribution outlets, like the ones mentioned in the forums.
Over the last 9 months 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.
To identify the genuine MagneFine filter from the Knock off. Just remove the label and if the "MagneFine" name is not molded into the cap then it is the Knock off not a genuine MagneFine.
All of the previous sources for a genuine re-labeled MagneFine filter, are currently selling another brand of filter. That includes ATP (their own brand), CARDONE (their own brand), FORD (re-labeled FILTRAN), NAPA (re-labeled CHINA), RAYBESTOS (re-labeled CHINA), SPX (re-labeled FILTRAN), etc.
