Transmission will not go into any gears

Won't shift into any gears. Started with transmission leak, found out that both bands reverse and intermete bands were bad, so replaced both bands. Also replaced pressure sensor solenoid valve, and replaced out put speed sensor and new transmission pan and gasket and filter. Checked both shift solenoids are good. Cable is fine. I put it in neutral and you hear a high pitch sound. And speedometer not working. Replaced transmission fluid with VI transmission fluid as owner manual says, put 7 quarters. Some leaked out. But isn't leak in anymore. Just won't shift into any gears?
