If it has a restrictor, it should be removed for transmission use.

Plumb it across the cooler lines (run in parallel to the cooler)...take out the restrictor. The differential across the cooler circuit will be enough to drive the flow through the MG. You cannot possibly move enough through the filter to reduce cooling to any effective degree.
Drop ralph an email. He knows how to convert them over to a tranny filter. Has something to do with drilling a bypass
It's a little difficult to drill the element bypass orifice in a MG-30 after it has been assembled. There has to be a groove in the bottom of the bottom seal so that the orifice won't be covered. The MG-60 is easy, all you need to do is reach into the outlet port and drill thru into the center. A 7/64th drill should do the trick. The other ways mentioned will also work. The restrictor orifice should always be used when you are pulling oil out of the high pressure system and returning it to the sump or oil pan. My Camry has about 16 PSI in the oil lines to the cooler. that would be plenty to feed the filter and return the fluid to the tranny oil pan. If you don't mind removing the oil pan you can get the drain plug kit at some auto parts stores. You can make a ATF adapter with two tees and a restrictor orifice. For big trannys you can install a remote oil filter mount for a 3/4" 16 filter such as a Motor Craft FL 1A. Then if you want a submicronic filter install a sandwich adapter and run hoses to it. I did that on a Dodge Cummins. After a trip to the West Coast the TP was loaded with wear particles. That's not unusual for a new tranny. The second change is normally a lot cleaner.

Help me understand this; I’m not trying to reinvent the wheel I just need to understand how this works before I am comfortable installing a MG filter.
What is the element bypass orifice, and how does it work? How does the lube filter work as oppose to the ATF filter?
I own a MG-30 air filter so I am not quite sure how that differs from lube filter.
I think on the lube filter you restrict the flow to the filter somehow and oil flows through one end of the TP to the other then through the center of the roll and out?
On an ATF there must be some groove from the in-port to the out-port to allow ATF oil to flow through the MG without going through the TP?
I would also then assume the fuel filter works much like a lube filter without the restrictor?
I would like to install an ATF filter in parallel with the oil cooler the Trans cooler and also a fuel filter. I am planning on getting the conversion kit for the MG-30 as well as a fuel filter form Ralph Woods, my father in-law says he has original MG-30 I can have for the oil.

I'm unsure of the actual, physical, modality that it uses ...but an ATF filter must pass much more oil if placed inline as opposed to a bypass that's tapping off of the main flow and discharging elsewhere. The flow through the cooler line is quite high. So, they put a proportional distribution device that divides the flow internally ..I believe it's a venturi deal for the discharge
If you just bridge the in
ut cooler lines ..no mod necessary ..'cept maybe getting rid of the restrictor.
The cooler and the lines will provide enough differenetial to push atf through the MG.

I don't know how the idea of the element bypass orifice got started. Normally the element bypass orifice is in a fitting that you put in one of the lines going to the cooler. The fluid goes thru the orifice on the way to or from the cooler. the orifice causes some of the fluid to be diverted from the up stream of the orifice and be returned to the downstream side of the orifice. If the filter gets clogged the orifice is large enough to handle the flow to the cooler. The orifice fitting is easy to make with two tees and a restrictor in between. Since the MG-30 can be drilled internally I felt that there would be an advantage. The reason I am going to drop the MG-30 ATF is some of the large transmissions are coming out with large fluid lines. Also the ATF filter will only work for cooler lines. At some point people will be trying to filter fuel or motor oil. They will work for motor oil if they are used in the motor oil cooler lines. There will be a reduced flow to the cooler with motor oil but it doesn't matter with motor oil. It just means the oil stays in the cooler longer. You can get a lot of motor oil thru an ATF filter when the oil is hot. I have never hooked up the filter in between the lines to the cooler. I have used the pressure drop thru the filter on some large systems. The same system is used for antifreeze by tapping into the heater hoses. It seems to me that if you are tapping into the pressure side of the transmission and returning the clean fluid to the oil pan it would be the same as motor oil. You would leave the orifice in.
