Some time back - maybe a couple of years now - guys were talking about a fix for operating the 5. 9 on steep grades so you don't pump out the oil..... I had that happen on a very steep short stretch - maybe a 100% grade - 45 degrees for 100 feet - when I backed down - in 4WD Low Range - the path looked like I had punched a hole in the oil pan = that much oil - well over a qurat..... what is the fix and how much does it cost???? HOW can this not be considered a design deficiency????? I know the hill I was on is very very steep - but i get the impression this can happen at grades significantly less .....
