**UPDATE** After all this time, I have discovered my truck is a triplex, not a duplex, direct must not have been used for a long time, as it wasn't going in, and I knew the trans had been changed, so I thought it was a duplex, but Al Penino recognized the case number and told me that it's a triplex, so I started playing with it, got it shifting, and now it works perfectly, so....MORE SHIFTING FUN! Lol ! Thinking about trading, or selling my B67 to get something a little bigger ( B73, B75, R700, Brockway, Autocar, etc.....) Mine runs and drives great, it has a **13 speed triplex, double over**
