Google "9336 dipstick" or "62TE transmission dipstick".
There's lots of aftermarket ones listed, varying from ~$32-70.
The thing that scares me is, even the factory write-up states the dipstick doesn't seat all the way. You basically have to feel/listen for it to touch bottom. Seriously? They don't have a real ATF dipstick that you can replace the stupid "see dealer" cap with?
Not only that, you're supposed to refer to a temperature chart to approximate how may millimeters of ATF level are supposed to show on the stick. Like I've said in other threads, I understand these transmissions route fluid different ways depending on their temperature, which will account for a small level change, but this whole process is made out to be more complicated than it needs to be.
If ATF expanded and contracted as much as they want us to think it does, there'd be bottles breathing on the shelves.
