2007 2500HD Classic 6.6. My hydroboost was leaking so I replaced it with a rebuild unit from rockauto. Its a cordone I believe. I went with the 2011 version many have suggested here. During install I had to use the push rod and star retainer from my old unit as instructions said to do. It all installed beautifully. Just dropped right in. Flushed the system and bled it. The next morning I drove to work no problems. So happy.
After work I could not shift out of park. I dropped it into neutral to crank it and made it home. No joy.
I purchased a new brake switch but it didn't help. When I have my wife hold the brake after cranking it, I can have the switch in my hand and activate it by pressing it with a screwdriver it works fine, shifts out of park and brakes lights will shine.
I've reinstalled without the clip and with the clip but can't make it work like it should. What am I missing?
Thanks in advance for any help.
