auto trans rebuild kit help please

where can i find a good quality rebuild kit. I still have not been able to drain fluid. I m pretty sure i need a rebuild kit. If i get a rebuild kit should i get a new torque converter?

I can get any transmission part possible, also the converter should always be replaced, as well as the transmission cooler should be flushed with a product such as ATP transmission cooler flush and it would be a good idea to add an auxiliary transmission cooler in front of the AC condensor.
