It looks like the power steering lines go into transmission cooler I have a little leak at the bottom of the powers steering Reservoir and I wasn't sure if it was just a coincidence that now the power steering is low and the transmission is starting to slip
You should have a separate cooling coil for the power steering and a cooling radiator for the transmission however it may be that the two are positioned one behind the other making it look like they are connected, have a word with the guys in this forum though for specific help on your car :thumbup:.
It may be time for a transmission fluid service and a new power steering reservoir but check the fluid in the reservoir first to make sure it hasn't just been over filled, clean up the leak and monitor it for few days to confirm exactly what is leaking.
