Don't drive it until it is fixed, and the transmission fluid is refilled. As far as the dipstick tube is concerned, it really isn't hard to replace.
If you look at the pics below, they provide directions for replacing it. There is an O-ring where the tube presses into the transmission, so make sure to lubricate with ATF prior to installing it.
Let me know if this helps or if you have other questions. Also, you indicated a pic that was attached. It didn't show up, if possible, reload it and upload it so I can see what you're dealing with.
See pics below.
