I'm sure this has been posted before but I can't locate it. My '04 F150 4X4 (5.4) has an intermittent buzzing or humming noise coming from either under the hood or in the transmission area. You hear it with transmission in "drive" and foot on the brake. Once you shift to "park", it completely goes away. It was really noisy early this morning (39 degrees outside). It may just be a coincidence but, living in the deep south, this was the lowest morning temperature in several months.
No problems with performance that I can tell. Runs good, gas mileage hasn't changed (still bad!)
With the mileage I'm driving, I'll be out of warranty in about 3 weeks.
I appreciate any input.
