My largest concern is with moving sediment around upon repressurizing clutch packs, solenoids, etc. It is a classic failure mode for transmissions that otherwise work fine, have no apparent problems, get a fluid change and then fail soon after. If you don't think it is a risk, then you should change the fluid. We aren't talking absolutes here, whereby every fluid change causes a subsequent failure, just a risk profile, whereby there are many failures that can be attributed to fluid changes.
The other risk is that the fluid has changed viscosity over time, and when you put new (thinner) fluid in, it doesn't work as well due to being thinner. The transmission adapts to different fluid characteristics over time.
FSETH actually saved me a lot of typing, thanks bud!
