2008 E70 transmision fluid leak

[Damager]

I have a 2008 E70 3.0i that I've owned for about a year. The car developed a leak in the transmission, and as soon as I noticed I called the dealer to fix.

I picked up the car today - they replaced the transmission sealing sleeve, pan gasket, pan plug and topped off the transmission with a quart of fluid.

I've seen lots of threads on this board about not messing with the trans fluid, and warnings that you can actually cause issues by doing this. Am I at any danger of developing bigger trans issues down the road due to having this leak and the resulting repair?

Thanks for any input you can provide.
