WTB - 48RE "open" filter

[LRutigliano]

I've been searching the net unsuccessfully for an "open" style 48RE trans filter. The stock Dodge filter is totally enclosed except at the bottom.



I'm running a MH DD pan and the filter is way down in the bottom of the pan, so I don't need/want the stock filter that only draws fluid from the bottom.



Do you know where I can purchase this or what the supplier/part number is??



Thanks,

Louis

The filters for the '94-'97 trucks is open, and they are supposed to be interchangeable with the newer style. The open filter takes three mounting bolts instead of two, but the third bolt is already there in the transmission.

I use the open filter listed above in my 48RE with the Mag-Hytec double deep pan. TDR member James Northrum, a DTT transmission rebuilder in the DFW area, suggested that I use that filter instead of the "closed" filter.

I also used the open filter from earlier models, it is what DTT installed on my transmission after the rebuild. I had to go back to the enclosed filter because of foaming issues, Bill or Stefan told me, some have foaming issues, some do not.

Yeh, the open style was used in the earlier 47rh model transmission's. Dodge went to the closed style due to cavitation in some transmissions.

This is probably a stupid question but out of curiosity, why isn't the filter lowered deeper into the pan when an aftermarket deep pan is used?

my MH DD came with spacer so it is at the bottom of pan on my 06.

That's interesting, because I'm reasonably certain the last time I changed the fluid the filter just bolted to the valve body with those two torx screws, or I'm loosing my mind!!!!

yep, there should be a billet aluminum spacer bolted to the valve body that lower filter down.

Thank you guys. I stopped by Source Automotive on the way home tonight and Rip set me up...

Thanks, I will locate and purchase one before my next trans service. On another note, running the unit as is shouldn't pose any problems should it? After all isn't the pick-up at the stock fluid depth?



Although I remember servicing my ATS trans last year, I'm "almost" sure there wasn't a spacer. However, around April I took out the input shaft and had Jeff Garmon rebuild the transmission for me, so I'll give him a call to verify what the trans went back together with.



Thanks again for the info.

Not sure it makes a whole lot of difference if the extension is on there. If the trans is full there will still be adequate fluid around the filter with the extra just a reservoir. With the amount of turbulence in the fluid its doubtful there is a gain either way.



On the other hand, the heavier wear particles will settle to the bottom and tend to stay there. Pulling fluid from above that may be a good thing.

Interesting food for thought.
