I drained/filled trans yesterday, but went I went to change my external filter the nut on the cap was stripped and I cannot get a socket to stay on it, so I need to replace at least the cap if not the whole housing. I hope I can get the cap off, replace it and save the rest of the housing. Has anyone else run into this? Does anyone know the part number for the housing and cap? What does the inside of the housing look like (I may have to crush or drill through the cap to get it off)?
