A bit of pondering on teh AW4 and filtration

With the quality and durability of the AW4 riding on a good clean supply of ATF, has anyone ever experimented with adding a filter to the mix? A real filter?

I wonder this because in my little 4 banger car, there is a filter, much like the oil filter (only red) that is for trans fluid.

Now would this be overkill for the AW4? And how would someone add that in? inline with a cooler? Not that I am planning on it, just wanted to spark some ideas.

I've seen mention of them before, and I'm sure that there are companies that make generic add on external filters. But honestly, with the number of AW-4s that have been reported with 200K+, why bother? Heat is what kills these transmissions, not contaminated fluid.

I was going to add a spin-on filter as part of an overhaul on my 87, until the damned City got involved and made me get rid of the truck.

The AW4's internal "filter" is really a metal screen with about a 1/16" mesh, so adding a full-flow element (like the oil filter) wouldn't be a bad idea. I don't recall which line is which, but plumb it into the cooler line going to the cooler, so the fluid gets filtered before it gets cooled (filter feed flow is better in that line.)

Suggest the filter be mounted "pendant style" (open end up,) as this will help with not making a mess when you remove it and you'll be able to pour it full of fluid before mounting the new one (which keeps a half-quart to one-quart "dry spot" out of the system. Yes, I know that a dry run shouldn't happen with fluid being picked up by the sump - but you're going to have to put in extra fluid for the filter anyhow, so just put it in the filter when you change it and you won't have to keep track.)
