Most 360s I have ever dealt with used the 727 type heavy duty trans. What is this "push button overdrive trans" you are talking about? I believe the V6 would be using a trans based on the light duty 904 regardless of what it is called and if that is correct the V6 converter would have the smaller neck. Therefore the 360 converter would not fit into the V6 trans front pump. I would test fit the converter to the trans before I got too far down the road with this swap. Good luck.
