Two things come to mind right away, 195 at idle is way high, temps should drop lower then that. The block mounted heat exchanger will balance the temps from the trans to engine, if the trans temps are high it will drive up CTs.

Check the cooling stack for blockage

Check the bypass valve in the front trans heat exchanger for stuck in bypass mode (not 100% sure on this)

Check the fan clutch
