1998 chevy tahoe transmission leak

[rachel]

I recently had a used transmission put in my tahoe due to the old one going out the guy also replaced the front seal and now a week later after parking it i come outside to see that all the transmission fluid has leaked out. wasnt home long maybe a hour or two. theres no fluid in it anymore. i dont know much about transmissions so i dont even know where to start to figure it out. im broke at this moment so cant have anyone come check it out yet so i was wondering if anyone could tell me how to check it out and what to look for etc to figure out what it could be i know i also need to replace two donut gaskets on my exhaust possibly the catalytic converter not sure. could that mess it up? any advice would be great thank you

if no fluid shows on the stick then check to see if it is leaking out the pan as well. doughnuts should not have done any tranny harm.
