I have an LB7 with 143,000m.  I have had the edge on this truck for the last 8000 miles.  I run the edge on level 1 and sometimes 3 to achieve the best mileage.  I don't two very much,  when I do it's a 17ft car trailer that weighs 3500lbs.   I noticed recently when the trans is shifting the slip percentage goes all over the place and returns to 0 unless I'm increasing speed or going up a hill.  Is the slip percentage something to worry about?  What is normal for the Ally?  Thanks!
