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

Then once it's gotten a few hundred km on it, I'll take the car and and broken trans to the trans shop and ask him to repair and refit it.

that way it will be his responsibility to make sure it works properly, not mine.

If anyone else has any more opinions or advice I'd be interested hear.
