Have you done a full flush or drain & fill with Toyota Tranny Fluid EVER?

Default work

hate to tell you this...

but I'd check your connections AGAIN - make sure they're tight and also check to make sure you didn't get the Distributor/rotors wet. Look inside where the wires plug into the Distributor and also the coils.
Might have got some condensation - steam in there if you used hot water to spray off.
