B&M 22301 NAG-1 Locking Transmission Dipstick

Alls I can say is I have owned my 05 Magnum for a while now. Never being able to check all my fluids drives me nuts. I understand to check this properly you need a starscan for temps and the miller tool for dipstick measurements. This has a cold spot for fluid and a hot spot. You can also finally get a look at your fluid to check its color. I give it 4 for being there. I have. Total accuracy on the levels I cannot say for sure. I do have the 5.7 version. Take note what you are buying though. These are made for the different motors offered by chrysler.
