transmission filter?

[glw]

Hello, I have an o4 dodge 2500 diesel truck and I am interested in installing a tp filter on the transmission. Anyone here done this, what kind of pressure might be on the line or flow volume. What would the service interval be? With the service interval recomended by dodge and the cost of atf+4 this seems like a good idea.

Thanks, Gene

Service interval, yearly or when it clogs! Might be good to change the 1st roll early.

Its a bypass, just parallel plumb T-it in as close to the tranny and return the flow to the pan. The restriction(TP and/or orifice) will keep ATF flow loss through the stock cooler minimal. The stock ATF cooler/plumbing will provide enough resistance to send ATF through the bypass. And, if the TP clogs, you'll just end up with normal full flow.

Another option is a series full flow, combination series filter like the Trasko, or the Amsoil dual remote mount. These won't need a return hole drilled/punched into the pan that a true remote bypass needs.

I installed a hydraulic filter from Graingers on my stepsons Ford Probe because the trans. (CD4E) only has an internal screen. It is a flow thru setup and has a 15psi bypass and you can put in a gauge to tell when it is close to bypassing. We started with a 2 micron but it plugged in 100
miles, So we installed a 10 micron and it is good so far. I got the idea from one of the 4X4 sites.

Quint, got any part numbers, and did you think about running the 10 for a few hundred miles, then switching back to the 2? KInd of as a clean up of 10 um particles then to get the 2 um particles out.

Not sure if this helps, but I have installed the Amsoil dual [parallel] bypass mount with two of the larger (I think 4.25"x10") Amsoil bypass filters EaBP-110 before the radiator cooler in my '00 Subaru Outback and the transmission seems to shift fine, so I don't think the dp across it is too much.

I'm not sure [yet] how much dp there is, but I have a Cyberdyne pressure transmitter installed at the inlet to the filter mount, but haven't wired it to the gauge yet.

I would think the tp filter would work fine if you have a dp relief valve with a reasonable setting in parallel, [as long as you don't get 'oil hammer', you know like water hammer??] --Louis

I put a Magnefine on my wife's 850 turbo Volvo as a full flow filter just before the cooler. I did it at 155k miles and wish that I had done it 10 years ago when it was new.

I ordered a motor guard tp filter from Mr. Wood for the transmission. Looks like I'll T the output line and punch the pan for return. This seems to be the easy way to go and cheapest. The engine tp filter was installed last week and I am impressed with the clean oil on the dip stick. Thanks for all the info.

Shaman, the part #'s 4ZC86 filter head, 4ZC81 3 micron filter, 1R412 10 micron filter, both filters are cellulose, 2C492 30psi gage. My setup was done for less than $50. Not to knock the magnefine but it doesn't really have the capacity but is great if the tranny is new or rebuilt. And yes there is enough room even in a Ford Probe to mount this.

I think you can get the filter head cheaper at northerntool. $13.xx+s&h for the standard filter and head. They don't appear to have too many filter options ..but you can save some bucks. Wix appears to have most of the hydraulic filters that you could use ..but they don't appear to get down to the really fine micron ratings.

Magnefine is small, but it allows anyone to put auxillary filtration on any AT with minimal work and in tight places.

You're right about it being a good idea for any refreshed trans. That's where I saw my first one ..when my trans lunched and got rebuilt.

Hi Gene: I put a Motor Gard by-pass tranny filter on my 2005 CTD with good success. Mounted a filter housing from Perma-Cool on the driver's side engine, ran high pressure hose to the Motor Gard By-Pass and back. Works great with an Amsoil std filter but would not work with Fram filter as it had too little restriction to send oil to the by-pass filter. The by-pass is mounted on the passenger side of the engine. You would like the setup. Harry

There are a lot of ways of doing it. On a Dodge Cummins I installed a Perma-Cool remote filter mount that takes a 3/4"-16 thread filter. I put a Perma-Cool 181 Ford sandwich adapter on it and screwed on a Ford FL1A filter. I ran two hoses from the sandwich adapter to the MG-60. After a trip to California pulling a show car I was surprised to see the MG loaded with wear particles. On a dual remote system I expected to mostly only the stuff too small to be filtered out by the spin on filter. I hoped all the wear particles were from the new transmission being broken in. Sometimes it takes a few filter changes to see how good the transmission is. I would never see that much in my Ford C-6. After 20 years it is well broken in. The internal filter on the C-6 is pretty much a joke. I haven't done it yet but I'll bet you could put a tee in one of the fluid lines to the cooler for pressure and return the fluid to the oil pan with a self tapping hollow bolt to a drain plug kit from the auto parts store. On the fluid lines that are 3/8" and smaller you can drill the MG-60 with a 7/32" element bypass. You can remove the orifice if equipped and reach in with a drill bit and drill the wall that you see when looking in the out port. Then you could just hook it up in series with the oil cooler. You could do that with the larger fluid lines if you know what size to drill the element bypass orifice. One of the advantages of the MG-60 is the filter doesn't drain at shut down.
The MG-60 filters from the bottom up. To a Frantz user it would be the same as putting the Frantz upside down. It is messier to change than the Frantz or Motor Guard would be in high under the hood but after you get the transmission clean you don't need to change it very often. I wouldn't fool with the little mickey mouse transmission filters. If I didn't require submicronic filtration I would install a Perma-Cool transmission filter kit and screw on the spin on filter of my choice. An Amsoil user could screw on an Amsoil filter that fits a 3/4_16 filter mount. Because of the lower flow rate the filter will work better than it will on the engine.

You gotta go with what works

 

[quintdiesel]

Gary Allen, The reason that I didn't go with the the filter head from Northerntool.com is that it only has 2 attachment points where as the one from Grainger is a Parker and has 6 attachments for the mount. The only reason I went with this filter is because it was easy to install (in-line)and my stepson will change it when the gauge gets into the yellow range, about 12-15 psi. The bypass filter would be great but I could never get my stepson to change it, He hates the one on my truck (really old motorguard)and he only changed it once!

I put a Perma-Cool transmission cooler on my 04 F-350. Would it work to install a Motor Guard TP bypass filter in parallel with the cooler? Would I have to install a restrictor to get it flow and or not flow to much? I have two MG's on my bench one is probably going on the wifes Jetta TDI at some point in the future or maybe as coolant filter on the truck.
