i was using low range for a few minutes today through some mud on a dirt road. there was a loud whining or whiring noise from the t case area...what could this be? and alos the motor heated to 250 degrees(just before red zone). the electric fan came on and i stopped and it eventully cooled down at idle. but is it ok for it to heat up this much. it didnt boil over or anything but i just would hate to see something go wrong
