Angry Ford Explorer Power Lag

Hi, Recently, I've noticed that my 2003 Explorer has developed what appears to be a lack of power when under load - usually when driving uphill. Acceleration is poor and, when a gear change would be expected, the engine revs up and down but without any obvious change in speed. I don't know too much about automatic gearboxes but the only way I can describe what's happening is that is similar to clutch slip with a standard 'box. The problem isn't as obvious on the flat, although acceleration isn't great. Any ideas?

The fact that you notice an RPM change with no speed change, sounds like the transmission. The transmissions around that year for the Explorer had problems.
One trait that I have noticed with them, put the transmission in neutral, shift into reverse. Whenever they were going out, there was always a delay. It might take 2-5 seconds for it to engage, when it did, it was a hard engagement.
