Not accelerating when floored

[Pclaythomas]

Hey guys,
Here's my newest dilema....
When I floor the loud pedal, the engine revs but feels like the tranny is slipping or maybe the converters are clogged. If I let off, it goes back into gear or something. Any ideas?

I bet on clogged converter.

What RPM does it rev to?
