Strange Torque Converter ???

Hey,
I was just eyeballing it off the hood to sky line and its not mountain hills but great lakes hills. The hills that are only a 30-50 yards long but climb rather fast out of a little valleys area. I was probably high in saying 35% but 20-25% is probably closer.

Thanks for the reassurance in saying this situation sound normal. The only thing that is still holding me up is that the truck barely gains 1 mph going down the hill nor gain anything in RPMS. At least thats what the tac and speedo shows.

Would there be anyway to use the programer to test the tranny for problems. Like changing a shift point or luck-up point?

Thanks
