Multiple problems

[Treeharrell]

I have an 07 Explorer it has started making a loud humming sound when driving between 55-75 mph. Bearings have been replaced and did not fix the problem. After driving for a while the fan will kick into high gear when accelerating with a decrease in power. Temps are running in the normal range. We had to rebuild the transmission a year ago and have been having issues like these since then. Any ideas?

I would take it back to the place that rebuilt it and have them check it or have another transmission/auto shop to check it.

I’ve taken it back to the people who rebuilt it and they can’t find any problem
