Q: Transmission Leak and Check Engine Light on 1994 Chevrolet Lumina

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
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.

the check engine light needs to be diaged for the code and failed part. a shop can do that for you.
