722.9 check ball/check valve in need of some
hi. I am looking for 2 of the black/tan spring check valves in my valve body on my 09 e350 tranny 722.9. It was missing 2. Also had TCM repaired but still in limp mode. They said it’s mechincal related. Found 2 valves missing and they said I need them. Not sure how it was reprogrammed.That our I will need a whole valve body or tranny. Message me if you have any to spare. Trying to get car back up and running. Thanks Roger

Try Sonnax. Take a look at their valve body for the 722.9 to identify the part.

How in the world would you valve body be missing check valves??? Check valves don't just disappear. Can you send me a picture of where they go? Did you open the valve body assembly. I can rebuild the whole transmission with my eyes closed, the but the valve body is a whole different story. I have taken plenty apart for cleaning but you really have to be careful with these VB.
