My K75 didn't have the tool kit when I bought it early this summer and as a result, I have had no way to properly check the level of the transmission fluid. I ordered this one off of eBay and I'm wondering if it's the correct wrench? It looks a little different than what is shown in the owners manual.

Also, are there suppose to be markings for the transmission fluid level? or is it just to the top of the rounded part on the handle of the wrench? When go to check the level of my fluid with this wrench, I don't get any reading at all (not even the very bottom gets wet with fluid). Either my level is real low, or this is the wrong wrench.
