External auto tranny filter

What is the interval for the replacement on this one? I can't seem to find it. Thanks

Change every 15k miles.

Those have external tranny filters?

There are a few things from this website that you need to be careful about (including that the tranny fluid must be MERCON SP, not MERCRON SP). However, it is a decent video. At about 5 minutes in, he covers the external filter change.

Here is my filter change procedure:

Change External Filter:
Loosen the filter bowl w/ an impact wrench - 7/8 inch socket or 22 mm.
Remove bowl by hand and discard all old fluid.
Do not throw out the bottom spring assembly.
Clean up the bowl, spring assembly and upper fitting with paper towels. Be careful not to get dirt into anything. There is a magnet on the spring assembly - be sure and clean it off.
Insert new, dry filter element into upper fitting (filter base that the housing screws into)
Make sure it is in properly and the tube is not crimped.
Insert the bottom spring assembly into filter element.
Make sure it is in properly and the tube is not crimped.
Fill up the bowl 3/4 of the way with new, clean fluid. Just a few ounces needed.
Slowly lift it up around the filter element.
Move slowly so the filter element absorbs the fluid.
When the bowl meets the threads of the upper assembly,
Slowly start screwing the bowl on by hand.
Once the threads are properly started, screw it on all the way by hand.
Hit it for 2 or 3 hammers with impact wrench.
You are done - now clean up! Be sure to check for leaks after a short drive.

Great thanks Mark! I'm way over due on this change the good thing is that I don't pull very often, and the truck sees mostly highway miles, but I'm over 10k over on the change. I thought it was at 20k, but that would still make me late on the maintenance

Now that you say 20k, it seems to ring a bell. Even if it is 20k, to me it makes more sense to do it at 15k since the tranny flush / fluid change is every 30k. It all fits together better at 15k and 30k intervals.

I just read my manual I saw 30k ? not that more isn't better

That's true, more is better anyway. I'm kind of a slacker sometimes with extra maint. items. I wil get it done as soon as I get the filter in the mail.
