the"Busted knuckle duster"

Do you have some info on it. Did you get it from dealership? If I even new how far the dipstick went past the tube i could fill it and check it . Nobody knows anything at the dealership around here makes me wonder if they even know how to check them when they come in for service.
So here is the idea........The tubes vary in length between models. There is a bulge on the tool just before the part that goes into the oil (dipstick part". The tool gets pushed down until that bulge reaches a restriction (can't go any further)where the tube enters the transmission. This places the "dipstick part" into the oil. When hot, the "dipstick part" is covered almost to the bulge. Here is a reference pic of the tool the numbers don't really man anything. There are all kinds of them out there, but all have the same idea. I have a drawing of the relative measurements that I will try to find and post.

I agree, the dealers have no idea what they are talking about. I had a leak at the electrical connector and had no idea how low the trans level was. I went to the dealer and had to help the guy work the tool down the tube (it barely fit). It came out with just a drop on the tip and he said it should be Ok.......LOL, I bought a tool and do it myself now.
