OK, even though I got no respose to my question about taking the manual valve out without losing anything, I decided that I would go ahead and remove it. So, if anyone wants to know, yes, you can take the manual valve out of a A4LD transmission while still in the truck. I loosened the valve body up a bit so it would slide out, but it did, and it should go back in just as easy.
However, now I have a question on where I can find a manual valve without having to replace the entire valve body.
Any ideas of a good source? I do feel I can finish it myself without any advice, (since nobody does seem to know about the A4LD transmission here), but I need to find a source for the part.
Any ideas? Ford wanted $300 for a new valve body.
