One day when I was working at Napa, a customer came in and told us how the Valvoline Instant Oil Change down the street got one of those tubes broken off in his transmission dipstick tube. They tried to put the dipstick back in and act like nothing happened, customer called them out on it, then they dropped the transmission pan to get it out. The customer came to Napa to buy a trans filter kit so they could button it back up.
