So, my stuff started slipping below 40 degrees F. My grandson and I pulled all the clutch plates, cleaned everything up and put the case cover back on. I installed a second factory diaphragm. I also use black rtv so I am waiting for it to cure and will probably take it out for a spin tomorrow. After installation, i checked clutch and have good firm pressure, seems to be no different than before. Thank you Sean Morley for the advice, maybe I should have ordered the HD from you.
