Before you jump ship and purchase a new tranny, you might want to tackle the pressure regulator. A stiffer spring from your after market supplier or shimming the one you have in there (be careful that it's a right diameter washer). If you choose the shimming route, a washer about .050-.060 inches thick should supply enough boost. The Breakaway converter has a flow path for volume different than the old converter and you're losing volume which through your valve body results in lower pressure. The spring is located in the pump body opposite of the orifice for the filter housing. Yes dropping the pan and fluid is required to do this.
