Good you found it. How about a coat hanger wire with a slight hook bend at the end: if you get it to go through the tube and hook on at the far end.
Worst case scenario if you still cant get it out. Maybe you can melt it with a blowtorch through the tranny and drain it out in liquid form.
ended up getting it out with a coat hanger. Thanks for the tips, everyone. the Endoscope was priceless.
I bent a coat hanger tip to make a hook to fit inside the hose. Then was able to lift it vertically and take it out of the drain plug. I actually had a dream about pulling it out this was causing me such anxiety lol.
Phew, glad that had a happy ending and a good lesson for us all! I have a little endoscope I got years ago for doing plumbing work, never thought about it having an automotive use as well!! I'm getting ready to change the spark plugs in my daughter's old 2012 Sienna and seeing SO many warning about the little plastic clips on the plugs breaking when you remove them (plastic becomes brittle from the heat) so I've ordered 6 new cl ones just to have replacements in case some of them do break. (But I've learned to lift up on the tab with a small screwdriver or pick, never push down the other end, which makes breaking it much more likely.)
So, next time you change the transmission fluid, wrap a piece of tape or wire around the tubing outside of the fill hole, make a flag with the end such that it won't be possible for the tube to fall in. Posted via the PriusChat mobile app.
Measure the ID of the fill hole, note it, and before next time score a complete funnel extension hose with slightly smaller OD. FWIW, with 3rd gen hose OD of 5/8” (16 mm) is about the max.
Ended up buying a long hose that fits (1/2") I live about 40min away from the nearest parts store and sometimes not going into town to get the right part isn't the best idea. Especially trying to work between rain storms. Been working on my own cars about 20 years now and it's funny the lessons you learn over and over again. Rushing can defiantly get me.
