Go Westy has an opinion on this:  Every 30k with filter change.   My newer
cars say never, or at 100k.  More here:

AFT is subject to heat breakdown, but as long as it is nice and red (not
brown) it's usually okay.  With all my cars I do 75k changes with Red Line
ATF which takes a lot more heat.   Unfortunately it takes three changes to
get all the old ATF down to a small amount (< 1/4 cup) since you can't drain
the torque converter.  If you want to spend the bucks do three changes
within a few days.

I don't remember for certain but some time (years) ago there was talk about
NOT changing the fluid in an auto tranny because it would have a negative
effect. Can someone  post the latest word on when or if to change the AT
fluid. I have a auto 85 Westy with 86K and I don't think the trans has ever
been serviced. Thanks for any info.
