Strange Sound during pushback

[f.skywalker]

When the aircraft is raised during pushback from the vehicle and the push has started, (Pushback car lift the Airplane)
i always hear a strange sound. I use PMDG 73x with MSFS.
When you push your leg, the sound rumbles.
It sounds like there are a lot of trolleys being driven around in the cabin.
It's hard to describe it. Luckily there is Google Translate.

Thanks Frank

I found the problem.
I have aktivated a mode Z_FM_738_V3.2
A flight Mode for the PMDG 738.
After deaktivating the Mode via SimLinker all works normal.

Thanks
Frank
