Having the same exact issue as post above (#5) on our pioneer 1000-5. Code 62 and occasional slip similar to putting in neutral. Shifts and runs perfectly until this randomly happens. This problem started happening to ours after a water crossing (about floorboard deep) Anyone able to diagnose the issue yet? Sometimes will run and shift perfect for 5 miles other times it will make it about 100 yards. All fluids have been changed since issue first started and still happening. It also occasionally stalls when going from park, into gear... but its not lurching forward like it's stuck clutch or anything, seems more like a safety switch killing it to me.
