Are the hard lines the same from the 200r4 to the 700r4? Or am I going to have to make another trip to the junkyard for some hard lines? Thanks.

The hard lines are the same, but the flow through the heat exchanger will be reversed as the in and out lines are in opposite locations on the two transmissions.

But there's no need to change anything then correct?

Correct.

Thanks Silicon!
