727 Help Please

Next question, can you post a picture of your input shaft, and stator support to make sure the years match up?

If just the front pump is removed from the transmission, you will be able to see if the input shaft broke free from the input hub. I doubt that happened, but a good visual check to ensure. Going to a neutral box is not very common. At least not in my experience.

You installed the valve body out of the box from turbo action correct? What is the part number in the valve body? Is it 17156?
I’ll check and see if it’s got a # engraved.
