Transmission Leak and Check Engine Light on 1994 Chevrolet Lumina

I was wondering what the estimate would be to fix a transmission leak which seems to be caused by the gasket having been overtightened, and to see why my check engine light comes on after I am driving on the highway for a while, or over 45 mph basically.
