zf 8hp transmission issue

Mollyran · 10-27-2019, 07:27 AM

I own 220i with ZF 8hp (and bootmod3 tune) 43k km

When I come to a stop and press parking, it's all smooth and fine but if i keep pressing the brakes, move to Drive and back to Parking (with out moving the car) there is a strong movement of the car/transmission.

The transmission is working normal, although more aggressive at S with the tune vs without it.

Is this behaviour normal?

Sounds like you're doing something abnormal. Stop putting it into park, back into drive, and back into park again....If I'm following what you're doing seems like something that is not necessary.

I did it once by accident, not doing it as a normal thing. But, I did tried it on other cars (not bmw) and didn't had the same issue.

What does other cars have to do with bmw? Absolutely nothing...

Other cars usually don't go from Park to Drive, they first go intro Neutral.
It's quite normal for a BMW to wanna start moving if you put it into Drive.
