N52 extreme high mileage atf fluid change

bimmerisalwaysbroken · 12-18-2021, 10:52 PM

Hi all so I've just picked up a 2005 E90 330I with ZF Auto transmission and I would like to do some maintenance on the car.

There are no maintenance records for the car but the transmission and engine are smooth and buttery. I've tried looking online for ATF fluid changes on high mileage N52's but all I've come up with are 100,000km guides.

Mine is currently at 190xxxkm and I would like to do a fluid change not a flush has anyone has any experience with almost 200xxxkm fluid changes?

At 200km, that wouldn't be a problem at all. Most owners probably would have changed it at 100k miles (if at all), so 200km isn't that far off. When I did mine for the first time at 90k miles (on a 2010 ZF e60), I couldn't tell the difference in transmission performance. Shifted smooth before and after.

Alright I'll give it a try but now the starter has died so it's gonna be about a month away till I get a new starter installed
