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 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.)
