Hi guys I am just wondering if I need to lubricate the gaskets on the fuel filter, and allison spin on filter when I replace them. You know how you rub oil on the oil filter gasket before you put it on. Do I need to do the same with the allison spin on filter, with I am assuming transmission fliud. Also on the fuel filter do I lubricate both the upper and lower gasket and assuming deisel fuel. Or do you just replace them dry.
