I would suggest a scan with STAR and check transmission fluid. You may have worn friction plates. Assuming when you say really slow is actually really slow and not just intercooler pump related.

Sounds like the torque converter to me.

As far as I know, there is no alternative to STAR for reading response times etc for an overview of your transmission health. The wealth of information they can pull amazes me. Maybe a trip to the dealer for a scan...
