Is the difference between the two of any real consequence on an unmodified/lightly modified vehicle? Thanks.

Maybe.

It honestly just depends. There are definitely differences between the 2 and it isn't possible to directly swap them without a tune to compensate for one difference, but the 4R75W is definitely stronger.

But, I have seen the 4R70W last for a VERY long time on lightly modified vehicles.
