727 trans rear band and drum shot

Thank you all for the above help! I will call a and a and speak to them about what I should do to make this trans live. I'll post back what they say.

Now, I should probably flush my converter.......I see people drill and tap a not plug on the side so they can fill with cleaner and dump it out . Then just install a plug. Seems easy enough......don't want to spend a lot to have it cut open and re welded. Thoughts ?

You will never ever get all the crap out doing it that way. Band and clutch material sticks like gooey snot. Will it work, probably. Would it be better to have it flushed the right way, absolutely. If you were rebuilding an engine and the block was cruddy would you douse it down with gasoline and use a wire brush to clean it? Same principal.

There's an old saying many shop owners said that holds true, "pay me now or pay me more later"...

And don't forget to flush the cooler. It'll be full of crud too
