ZF8 transmission in 330i -- Does yours “thump” after each shift?

I've only had my 330i for about 1500 miles/a little over a month, and was wondering if anyone else has noticed after every gear shifted, it will feel like a thump? (For lack of a better way to describe it.)

It is more pronounced in Sport mode as well. I was testing it this evening with one half and 3/4th throttle. Each shift of the gear will bring on another small thump right after the gear switch.

I had a F30 335 back in the day, which also had a ZF8 -- and it didn't behave like this.

I've not seen anyone post about this, and I was curious if this was just me. I'm half tempted to go test drive another 3 this weekend and see if it behaves similarly.

Thanks!
