    Its massive. And its garbage in a performance setting. There is a reason vette guys are spending 10-15k to swap to a 4l80.

    And the fact that a 4L80 was never meant to go into a vette and it takes a lot of custom parts to make an engine mounted Transmission mount to a transaxle and work but none the less a much tougher transmission, but ANYWAYS who dafuq is buying an automatic vette? Lol
