Totally a hypothetical question ;)

If you just simply drive the car, the trans may very well be OK. I’d do what Rainy said and pull the pan to check it.

I destroyed a trans due to self inflicted shoddy work in a rush. 20 miles around town in 2 days and I was looking at junk connected to the engine.

In another incident, it was fine. The difference was the trans wasn’t subjected to a lot of around town driving but just light throttle cruising on the Hwy. low stress, low speed.
