Servicw 4wd light has kept popping up since saturday. truck has 66,000 miles on it. Would this be a service interval or is something up? have noticed hard shifting in the warmer weather, and once this light pops up can't shift into 4hi etc.

Push button. Trans fluid looks pretty clean yet. Have been thinking about changing it anyway. Local guy told me to switch the ATF to royal purple but am lenient.

Has nothing to do with the tranny. Can get the code ran for free at most auto parts places. 90% chance it is the switch itself or the actuator at the transfer case.
