I'm changing a cracked trans. case on a 700R4. The orig. has the aux. valve body and the replacement case the guy brought me is older and doesn't have the aux valve body. I have all the issues looked after with the change except the pump. The orig. pump has a hole for the aux valve body feed line and I didn't get an older pump to go with the case. If there's any trans techs out there, do you know if I can seal the feed hole in the pump with a plug. The pumps look ident. other than that oil line hole. Thanks Doug.
