I have an eg civic.
I have no idea how the guy did this but the frame rail where the tranny connects is tearing away from the body.
Is this a cheap fix or expensive and what needs to be done.
Im afraid to drive the car the motor is ripping apart from the frame,

 

sounds like a good donor for a tube chassis project, but prob not the answer you wanted

 

Weld in new metal. Only way to fix it. Are you able to post any pics up? Might help in a way to fix.

 

any idea on the cost to do that

 

not cheap but not too much.
take it to a shop for an estimate, frame work goes by an hourly rate usually so they will need to see it and estimate the amount of work, what will need to be removed to do work and all that stuff

 

is it just the motor mount bracket?>
