    What would have to happen for it to work on a 2003?

    I'm not sure what the difference is between the converters, but the model number for the latest model 4L80E is 25A-20L, instead of this one, which is 25-20L. I asked Hughes if they could convert this one to work with the newer trannies (since that's what I have now) and they said no.

    So the answer to your question is that you can't make it work with your 03 trans.

    Dropped it off at Hughes today, should have it back and ready to ship by Tuesday or Wednesday next week, just as good as a brand new one
