help troubleshooting

I have a 2001 expedition 4.6 4x4. Lately I have been had issues that I believe is transmission related but dont know how to properly diagnose the issue ie a tc, clutches, etc. While I am driving especialy up steep hills the rpm often start fluctuating about 300 rpm up and down. In adittion it sometimes will squeal until it down shifts (I am sure its not a belt squeal). Last the lower the rpm (overdrive) the worse it seems. The truck doesnt always do this but does off and on. I had replaced the fluid and added slip fix but doeent seem to help. I am going to do a filter change but after that dont know how to pin point the problem. Any ideas?
