How To Service A BMW E90 3 Series Transmission

Описание: In this video I show you how to service an automatic transmission in your E90 BMW. I'm working on my 2008 335i with an N54 motor.

This car has the 6HP21 transmission which also goes by 6HP19 or 6HP19TU. This is a 6 speed ZF transmission.

I show you how to change out the bridge seal and all the tube seals along with the solenoids which do go bad over time.

In my case I was getting a rough downshift to first gear. The likely culprit was the bridge seal.
