2008 Tribute: Transmission? or Computer issue?

Yesterday my wife was driving and said something is not right. The engine RPM was faster than it should be on the highway and a hard shift from start.

Well, we figured out that the car was skipping second gear and overdrive was not working. It would start in 1st just fine, but since second didn't exist, it would rev until it reached the appropriate speed to shift into 3rd. From there we could drive fine, but at 60mph or so we were already at 300RPM, and no shift down to overdrive.

The little "wrench" symbol comes on whenever we go through the first run through the gears, and stays on until the car is turned off. Overdrive switch causes light to come on dash but doesn't seem to affect transmission. Fluid is okay.

I don't want to run to a transmission place just yet and potentially get ripped off with an expensive overhaul that I might not need.

The problem started just after getting oil change at Walmart. Coincident??

Do you have a suggestion?
