I'm embarrassed to ask this question, but I can't find an answer after searching. I've got a 2005 Silverado 3500 4x4 duramax, and I checked my tranny fluid last night and I wasn't sure what I was seeing. It seems there are two sets of hash marks on the dip stick. One down toward the bottom and another a couple of inches up the stick. There are also notches along one side, which I assume are quart marks? Anyway, both sets of hash marks are pretty light, so I couldn't make out any details. My truck has started to occasionally hesitate and 'kick' just a little when I start to take off, which is why I was checking it.
