So I have decided to swap my 4r70w with a 4r100. difference being that I am going to put a manual valve body in the trans so that I can shift without help of the computer. Problem being is that I cant find a manual valve body for this trans. does anyone have any links or knows anyone that has one?

If I can't find a manual valve body for this trans than I will probably go with a th400 or c6. with that being said I know very little for either. which would be a better choice and able to handle 600rwhp being built up?

 

I've never seen a manual valve body for a 4R100. Maybe there is one somewhere out there.

 

I feel like I've seen them too. But I can't find one. If I use a c6 anyone know if it'll bolt up to my transfer case?
