Is there any advantage of using 6 over 5 disc direct drum? I know 6 will hold more lbs but is it worth the trouble. I'm using a 4L80E 34 sprag direct drum. I need to buy a aluminum piston the 2 sources I found said they could machine it to work with 6 disc or 5. It was my understanding that the 4L80E direct Drum has enough room for 6 disc if you remove the wavy and replace with steels.
