    Default AW4 Transmission and NP242 Transfer case temps

    Has anyone shot their transmission and transfer cases with an IR thermometer after running for an hour during the summer?

    I did yesterday evening (5pm to 6pm) 1 hour drive, probably 40 mph average. 165 degrees on the AW4 oil pan, and 155 to 165 on the bottom of the NP242 case, where the fluid is.

    Transfer case was in 2wd.
