There are some internal parts that make the C4 used with the 6 less strong.

Replace the tranny with a v8 one for a couple of reasons one they both are geared different and two a v8 makes more power its gonna break the tranny.And its a lot more work then just stuffing a v8 in it you know that right?What year is your car?

Have your c4 rebuilt to v8 spec or replace it.
