Rear differential

[grousehunter 61]

Low trans fluid is the problem, I crawled under the truck and found a large area of wet ground about where the the front of the trans was sitting, so I have a leak somewhere up front most likely the filler tube. without putting any more fluid in it and with it sitting level all night, enough fluid came to the back and old yella backed up, not great but it moved. With all the rain we have had the wet spot did not show until I got under the truck.
