A friend of mine has the rare find of a daughter who goes to college and works on her own car! She is quite handy; I once helped her R&R a water pump on her car on the side of a road.
Her mother mentioned to me today that she made a pretty big mistake while trying to put oil in her transmission (91 Buick Regal). Somehow, there was a plastic piece on the end of a funnel type thing which fell off and into the trans while she was trying to fill it. Apparently, she did not know that this plastic plug was on the end of it. She only realized it, after hearing it unplug and tumble into the trans.
I have no particular ideas on how to get it out, except, flushing the trans with oil and hoping that the item falls to the bottom. Does anyone have any other ideas??
