2007 Sport Trac Revving issue

[memphis212]

Hi everyone hoping you could help. We recently purchased a 2007 Sport Trac v8 with 78,000 miles. The plugs, fuel filter, and air filter have been replaced in the last 2,000 miles. My issue is that when driving between 35-50 mph in 6th gear the engine revs slightly from 1150 - 1300 rpms back and forth. When running ovr 60mph it does not have this issue. Does this sound like a bad torque converter? Any suggestions?

Greatly appreciate any help/suggestions.

I have the same exact truck and mine started doing this a few months ago with 62k miles. Ford checked it out and the only thing they could come up with was to change the spark plugs. I didnt do that. They believe the coil packs are ok. The tranny checked out. Like you, I only notice it in 6th gear at lower speeds. I am going to ignore it unless it gets worse
