I was looking for the proper tool to remove the transmission dipstick. I searched through the self help tips and the search menu to find a certain post that I remember reading to use a 3/8" allen wrench to remove the dipstick. Can anyone verify that this is the proper removal tool. Accomplishing my fluid service today and I do not have the right size allen wrench. Bought the service manual but it does not state the size of tool to utilize. Thanks for everyone's help.
