With the Mishimoto trans cooler installed and the thermostat by-passed . My trans doesn't get much over 120, most of the time it at 100 even with the torque converter cooler installed. heck I swear some times the Mishimoto trans cooler slows down my engine warm up times. I didn't think with torque converter cooler still inline I would have a problem with temps. is 100 to 130 to cool for a 48? it seems to shift fine, even goes into od and locked up when its 28 out. I kept the thermostat for the Mishimoto trans cooler so I could pop it back in. but I called Mishimoto to ask what temp the thermostat opened at and they said 180. That seems a little high, I thought the oem opened at 160ish but maybe I'm wrong. So whats your guys thoughts keep running it or put the thermostat back in?
