This is an old one - Merc said their autos were sealed for life and yet any number of V8 mercs (things like C43 and E55 from the late 90s) had gearbox troubles from 100k to 130k miles typically.
The cynics changed their ATF every 50k miles and never had any problems.

Needless to say i will be changing the ATF in my 'box at the next service (only just bought the car and it's on 62k miles).
