Rebuilt 904. Whirring. Dead?

Thanks guys.

I think one of these days I'd love to learn to built my own torqueflite.

I am going to put the standard 40+ year old trans and converter in the car just to run the motor in gently

Be sure to flush the cooler several times if you do this. If something let go, there's probably debris in the cooler.

Take it apart yourself. The 727/904 are as simple as they get!
