good morning guys,

so today i brought my car into the mazda dealership to get my 7500 mileage service. so i was waiting for my car to get it inspected and checked and the mechanic came up to me and told me that my car has a transmission fluid leak.

Some of the causes that I was told for this to happen was, improper placement of gasket and something loose

I've only had this car for 4 months now, and the last time i got my car serviced was 3500 miles. and i don't normally check my driveway to see if there was a drip of oil or liquid or anything because i back my car up into the driveway. plus i didn't know when this leak occurred, but i will be more aware of this.

So any suggestion of what will cause this? and what can this problem lead into?

info will be appreciated thanks!
