Trans oil change ?

I change mine min every other year but it boils down to how the ATF
is doing in reference to 'your' setup and 'your' driving style and
terrain driven

Most folks take this kind of stuff...heck everything...as a one size
fits all. Ditto those advising HOW2

I've changed out a fresh charge (about 500 miles) of Mobil Synthetic
engine oil, ATF, diff fluid after one extremely hard run from sea level
up to Lake Tahoe and back towing my +8.5K lb boat

Some use oil analysis and a good thing but not for me. Maybe will
if something seems amiss that can't figure out, but the ~$28 bucks
buys most of the oil/filters for me

Am old and been (still am) boy racer, wrench/gear-head, etc all my
life. So know enough about my rigs to understand that the oil in
question needs change because it has broken down enough for me to change

When the dash engine oil gauge starts to fluctuate, PSI down a bit
and the biggie...starts to consume...it is time or past time to change

No dash gauge for ATF, so know when the 'smell' and 'color' is off...but
with my every other year flush, it has only happened a couple times
and when knew abused the stuff

All of the OEM and even after market ATF sensors take it from the
test port....but....the lions share of the temp creation is inside
the TC and at the tips/edges of the vanes. So how would one measure
that?

So I like you, flush often and the cost is cheap compared to a rebuild
and/or stuck out in the boonies with questionable service providers...if
they can even be found...
