Hi, all I can say about your van rolling is that I have a 94-b150 that I bought awhile back. I placed it in park and it would roll back in reverse. I called the dealer and asked if that year had transmission problems. They told me no. They looked at it and found that I was missing a bolt or washer on the linkage on the transmission. Never has rolled since. Good luck on your other problems.
