the factory one is not stainless, I have a few and a magnet does stick to it. the gear oil could be making it stick inside, making it harder.

I would try a few more tricks before removing the drive... if you get another dip stick and coat it with something like "STP" oil treatment or something else that is really sticky and send it down and get the old one to stick to it, it could work.

before you start try cleaning out the hole with brake cleaner, just make sure the drain plug is out to drain out the excess

its out!!!! the hole is the size of a Bic pen its like trying to get the ink part out of the outer part except it was 6" down. I wound up buying every tool that i thought would help. I even bought one of those metal finger grabby things. The first one i bought would not fit down the hole. I found a diff one and that was able to go down the hole but there was no room to open the fingers. I had to bend each of the four metal fingers straight and with that and about a half an hour of trial and error i finally was able to grab the dipstick and bring it to the surface.

the tools that i magnetized were not strong enough to pull the dipstick away from the remaining oil. Thanks everyone for the advice
