i have to pull the tranny, some how my flex plate got warped. does anyone know how much a c4 weighs?

 

i couldnt tell you exactly, but I can lift the one on my shed floor to move it around. its not light!!!
I wouldnt want to try to lift it out of the car on my own...2 man job or better with a support stand under a hoist.

Assume thats why you were asking?

 

75 pounds??

 

Yeah, you will need a tranny jack.
