How do you know what color the fluid in the slave cylinder is? You have to drop the transmission to inspect the CSC. But if they're fixing it under warranty, you'll be fine until it craps out again
I would ask them to put in an aftermarket CSC solution (obviously they won't warranty it). Some dealers are good about that stuff, but many won't touch aftermarket.
If they'll put Motul 5.1 fluid at no charge to you, have them do that. Otherwise, just wait until after and put in Motul RBF600
