I need help bad...

I just had my tranny re-rebuilt and had the Transgo shift kit installed.

4 days later the tranny is slipping at start off and between every shift. Before this started I really didn't notice much difference in the characteristics of the tranny, as in the feel of the shift and when it shifts. I understand there are other benefits to the shift kit, I expected more. Should there be more?

Also, could the misapplication of the kit be causing my new troubles?

I have to get this thing back in right away so any "quick" response would be appreciated.
