Do E39 trannys also die around the 100k mark, like E34s?

the 528 has almost identical autotrans as the last 525is, the a4s310r and 270r, except that i think these are sealed. the tranny fluid should make it to 80k or so. the 525i from 2k on have a 5 speed auto tranny, don't know about its lineage, but they would be sealed also.

This shows the lineage of the later model 525, 530, 540 transmissions. Yes they are "sealed" and use the Esso ATF LT 71141 "lifetime" fluid.
