F30 ZF8HP vibration at ~2500 rpm

misloof · 11-13-2019, 03:14 AM

Hello everyone. I have a BMW F30 with 141k km (~87k miles) RWD. Transmission is automatic with ZF 8HP gearbox.

I've changed transmission oil and pan few days ago and noticed vibration when car accelerating about 40-80 km/h (25-50 mph) @ 2200-3000. Actually I've heard vibration before oil change, but I thought that issue gonna dissapear after service. I have no idea what can be the cause of vibration, so please write your advice what part i need to check or expirience with similar problem.

Here's a video:

Tnx.

Sounds like a resonating vibration - check covers/bolts etc are all tight and torqued to spec

Remove fill plug and check fluid level again, may have dropped

I would check and replace both driveshaft flex disks, in the correct way.
