Ray,
It is highly unlikely that the tranny is leaking on the cat. If you had 
overfilled it (have you replaced the fluid it recently?), it could be 
expelled from the breather hole on top of the transmission housing. But 
than it would drip down the housing, not sideways towards the cat.
I think it was Jeffrem on the UUC list that suggested that you check out 
the selector shaft seal.

I'm not sure I can follow the rigging instructions.

See above.
Hope this helps,
