I can't see the lines in the pic so not able to help you 100%. If the trans lines are running into the radiator then it is the 45RFE.
Another way to tell is to crawl under the Jeep and count the bolts in the transmission pan. If 15 bolts then you have the 45RFE. If there are 13 bolts in the trans pan then you have the 42RLE. I'm guessing you have the 45 since it appears the cooler lines are running into the radiator but count the pan bolts to make sure.
