Has anyone installed an external trans filter if so where did you get it . An also now that you have it how have you changed your service intervals on the internal filter .

 

Travel...
I know there are some who have put external filters on their Trans fluid... and make great claims. Like the motor, they are both too expensive to not go the extra mile to make sure that they stay sound.
I have a FS2500 for my oil and am very happy with it. One of the FS dealers runs a FS2500 on his trans as well, claiming 75,000 change intervals on a 2002 Dodge.
They are those who would discourage you from an inline trans filter stating that it woill restrict the flow and cause issues. Check that info with a trans person you trust. Should you choose to go forward, I would highly reccommend "Filtration Soultions", Randy is tops and a wealth of information.
Good luck

 

Here's te easy, inexpensive way I did it. Only change from this writeup I posted a couple months ago is I opened up the bypass orifice to about .040 for better flow:

Did the first service on it at 25k, installed a new shift solenoid and a Mag-Hytec pan. Old fluid looked OK, normal sediment on the pan magnet, trans shifts fine, everything seems good to go. But I could not help wondering how this monster diesel tranny is still getting along with basically the same filter they were using in the 727s back in the 60s. I was astonished to see that Mag-Hytec even recommends using the old style filter as being a better design. Huh?

So I got to looking around and found an elegantly simple, neat way to install a bypass filter in the cooler lines using a standard filter mount. There is about an eight inch section of 1/2" I.D. rubber on both lines near the bottom of the washer bottle. The top line is the hot/pressure side:

Located conveniently nearby is a cubby hole behind the bumper with plenty of space and a nice solid place on the core support mount to attach:

There is a .025" flow reducer on the filter input coming from the hot line so most of the oil continues to flow normally through the cooler. But there is enough of a pressure differential across the lines at this location to slowly push a small amount through the bypass filter. Removing the inner fender took all of 5 minutes and made installation a breeze:

Hopefully with regular service and set up like this, my tranny will last a bit longer than might otherwise be expected.

 

sounds good!
so what relocation kit did you buy? where?
