I had an uh oh moment the other day whilst planning my 100k services for my e9whatever 328i with an auto trans
Turns out no one ever did a transmission service before I got the car.
I had been told that the tranny was "lifetime" and "didn't need servicing" back when I was dumb and bought it and didn't know better, but now a days worth of forum trolling shows many people doing the trans services on my same car.
Does anyone know if they're are any issues with servicing a trans (filter and fluids) after this many miles? I've heard bad things about new, thinner fluid not flowing right in a tranny with seals worn out by thicker, old fluid but I am obviously not an expert here.
Any advice would be greatly appreciated.

"Lifetime" in BMW speak means "lasts long enough that they won't have to replace it under warranty".
There are two approaches you can take:
1. Just do the minimally required service and then just dump the car when an expensive repair comes up... or becomes a basketcase with several little things wrong that individually aren't too bad, but quite expensive when you add it all up.
2. Take preemptive steps (like changing the transmission fluid) so that you *might* avoid problems in the future. You might want to have a read here:

I was pretty much planning on a simple drain and filter since I'm sure it's never been done. I just didn't know if there was any truth to the idea that changing the fluid after such high milage can do more harm than good.
Good forum link though I hadn't seen that one. Thanks a bunch.

When people say things about there being issues with changing fluid, that's if you really neglect it or there's a lot of wear in the transmission. If you drain the fluid and it looks like bass boat/bumper car paint, you're screwed. All the shrapnel in the fluid gives it enough friction to move the vehicle around, the new fluid will be too slippery, and the transmission won't work.
If you drain it and it looks like transmission fluid, you're fine.

That does make a bunch of sense. I'll see if I can't sample the fluid when it's on the rack for the front brakes and find out just how screwed I am.

Correct. I know for a fact that my wife's trans has not been serviced in over 115,000 miles, on a model that has some history with premature auto transmission failure. As such, we don't even plan on doing it ever now, and cross our fingers that it just keeps going.

One of my dad's friends had a '92 F150 with the automatic. He asked my dad about doing the first transmission fluid change once it hit 160k. Dad pulled the dipstick, and the fluid was glittery (the guy did a lot of towing with it). He said it's too late to change it, and the only option was running it until it died.
It made it to just past 300k miles before the transmission failed completely.

Do it. You should be fine at that mileage. IIRC the filter is integral to the pan and the whole pan assembly must be replaced. Also suggest replacing the electrical connector sleeve as those have a tendency to leak.
