Have a BMW 2017 M140i with a ZF 8 speed automatic gearbox. Bought it a couple months back and it is currently at 95K KM mileage. Almost guaranteed that the previous owner did not do any maintenance work on this car. I had the engine oil changed but I am wondering should I flush or change the transmission fluid? Have read a bit about full flushing causing slippage issues hence unsure if I should proceed.

Any advice? Thanks!
