I need a new hot line from the tranny to the heat exchanger. When my tranny swap was done the lines from the 727 were used. I would like to use a line with the senser port in it. I don't know for sure, but have heard that the one first gens use is disontinued. The one that is used on the 2nd gens should fit better for me, but I read that it has a hose and check ball. I know people remove the ball, but I really don't want anything to do with the hose. I would like to use all hard line. Any ideas and or thoughts?

Thanks, Paul
