171 is on the high side of where you want it, ideally it should stay below 160.
That is average with an external cooler and moderate load.
Remeber, this is PAN temperature, so this is what is FEEDING your transmission, after all the cooling. For lower pumping losses (economy), 160-180 is good. 170 is fine.
