    Will this fit a 454 tbi chevy engine because the truck I have is a 1994 chevy 1500 4x4 with a 7.4 454 not the original 5.7 350

    Asked by: Israel c

    Do you all refund a portion of the cost like the parts places do when I turn my old transmission in. I don’t need it.

    Asked by: JonnyQuess
    We do not take transmission cores. You might try contacting a local transmission shop and see if they will purchase your core from you.
