DENNIS, look on the dip stick tube. There should be a mounting bracket with one mounting bolt. It should be a 10mm bolt, remove that. The dipstick tube should just pull out of the transmission. You may have to twist it hard a couple of times. Even so it is a simple pressfit, it may still be pretty tight and may need some "convincing" to be removed. When replacing the old dipstick tube there is an O-ring on the the bottom, about 1 inch up from the end. Use some RTV sealant on that O-ring before installing it back onto the transmission. I also find that it helps to place the new tube in the freezer until you are ready to install it. This will contract the tube slightly and will make it easier to reinstall. The pressfit and the small bracket are enough to hold the tube in place. Hope this helps, good luck.
