new 727 & converter; stumped

I was thinking that the gears might have something to do with it but thought later that youre talking about before the car even starts to move.

Sounds like the converter is to big. Friend of mine installed a 3000 and it would whine up ... he later installed a 2500 and liked it better. His car was street drove only so he didn't need all that stall. That thing would go through some gas with that 3000 stall.
