2001 Pontiac Montana Van....Transmission gasket leak, 112,000 ?

[Billboxing]

My wife drives a 2001 Pontiac Montana van, that we bought new and have kept in good running order. Wish they still made them, This was our second and love it, compared to Dodge Caravan, that was so so . Was told today at a local oil change outlet that she had a small leak from a transmission gasket. I know there is a hose with a coupling attachment, is this what they were taking about, or something different ? Thanks for any help.
Thank you both for your help. It's appreciated. Wish I could give you both best answer.

those are nice vans. probably just the pan gasket needs to be snugged up some.the bolts will work loose over a period of time.
