Did you get to see the fluid when it was changed?
Problem with changing tranny oil at such high mileage is that the sludge buildup in the transmission may loosen with the new oil and clog other areas of the tranny.
You change at 50-60k miles to prevent the sludge buildup.

BTW thats a good ZF procedure doc there with the flowchart.. essentially the procedure I used.
Hi,

I've done the e39 procedure attached twice, on my e39, using an IR gun. No issues. Car has 270k miles and trainy rock solid still. So im comfortable doing that, but that flow chart has a lot more steps in it. Looking at the attached, would it work just the same (like you did yours)?
