Anyone running an inline transmission filter? If so what brand? I am putting a new tranny and thought might be a good idea but looking at binder planet looks like no one really running them for their 727's.

No, but I have one in my power steering return line.

Sounds like a good idea to me.

I’ve only met one person who ran an external AT filter. He mounted an empty radiator under the bed of his pickup truck and used the built in AT cooler with a filter as his cooler. I didn’t think about it then, but when I think about it now...he’s carrying a spare radiator lol.

I just looked on eBay, there are many.

Yeah there are plenty of options but one post i read made a good point... if the filter gets clogged there is a risk of starving the tranny from receiving fluid.

I had that happen with my power steering recently, not working at all. Removed the filter and it worked again. I was up in the mountains without a spare. This tells me there's a need for the filter though, "something's" clogging it up. So change it regularly or carry a spare.

There’s a filter in the AT too, you’ll see it when you drop the pan. If you have an external filter it would should extend the life of the one in the pan and is easier to change an external filter if you do a lot of fluid changes.

^This.

hi,
If you want the very best inline transmission filter money can buy, get a Wix base, part number 24770 and screw a Baldwin B7311-MPG filter onto it and plumb it into your trans cooler line. This is also the very best filter we could ever put on our IH engine too. Here's a little bit about that filter:

I looked at about 300 different Wix and Baldwin filters that will work on a IH V8 and this filter flows much better than any other filter I've found (10 gallons per minute at only 3 psi, while other filters require 10 to 20 psi to achieve this flow), resulting in the least pressure restriction/drop of any of the filters. This has the resulting benefit of allowing the highest possible oil pressure throughout the engine (or trans) of any of those filters. (This is important for our low pressure engines). And it does this while providing the finest particle filtration of ANY full-flow filter I’ve ever found that will fit our engines, (trapping particles 4 times smaller than a stock 51515 filter). This high-end synthetic media filter has smaller passages to trap smaller particles, but can also pass more fluid through because it has more passages, thus increasing the inherent surface area. It provides 5 micron nominal and 20 micron absolute filtration as opposed to the Wix 51515’s 21 micron nominal rating and unknown absolute micron rating. (In other words, the B7311-MPG filters far better than any other Wix or Baldwin filter, my most important requirement for a filter, while providing the LEAST resistance to flow and therefore the highest oil pressure to the engine of any filter I know, my second most important filter requirement).

This filter holds 32.4 grams of contaminants in 463.1 sq. in. of filtration media, which is more than any stock filter, but not as much as other 7 inch filters. Therefore this filter is best on regularly maintained engines for keeping the oil absolutely the cleanest of any full-flow filter I’ve found. But for a very dirty engine that has not had its oil changed regularly, you may want to first use the BT217 or BT237 as they hold the most contaminants of any filter at 49.5 grams.
Of course the largest, most efficient filter with the finest filtration with the best flow with the least pressure/flow restriction causing the least pressure drop comes with almost the highest retail price of any filter, just under $14 a filter the last time I checked.

And for my recommendations on the best inline fuel filter presently available, use a Wix base 24770 and a Baldwin BF7633 (2 micron nominal, 5 absolute at 98.11% average efficiency with 651.5 sq in of filtering media capable of holding 25.4 grams of contaminants, and tested with 0 to 50 psi pulses 100,000 times). This high-capacity spin-on gasoline filter should go between the gas tank and fuel pump, as contrasted to the little plastic or metal in-line gas filters that have between 12 and 140 micron nominal filtering capability and ? absolute filtering capability.

The thread may start out lame, but it gets better as you read through it.
Thanks, and good luck with your filter project.

As a follow-up, if you were running a manual transmission, IH has been making manual transmission filter kits too since the 1960's. I could give you all the IH part numbers if you want, but here is a reproduction manual transmission filter kit that should work as well as an original IH kit:
