I would also add that you should add a Sonnax differential lube line retainer, part# 84532-01K. The differential lube line is known to sometimes fall out since it has nothing holding it in, and has a rubber section of hose. It will cause excessive differential wear, and eventually failure of the differential. I bought a few and will always install one when I have the pan off of a 4t65e. They're very inexpensive, $1.96 +shipping on rockauto.
