I read your other post. As I said, I have a transmission that is good that you can just have, but also, I think I have that shift select valve from another trans. You can have it, also. They also will be readily available on Ebay, and not very hard to change. You will need to pull the valve body down to get enough room to pull it out, but that's all it does. It pulls straight out, and a replacement goes straight in. Second, it may seem obvious, but you were checking fluid level with the engine running, on level ground in park or neutral, correct? I have to ask. People do get that wrong.
