I did this mod and definitely think it's worth it. The bell housing was very hard to find in this area and took me months. I finally spotted an ad for a late model AX15 tranny for sale and called the guy and offered to just buy the bell housing..He thought they were one piece but when he looked at it, he said yes so I got it. And he still was able to sell the tranny to someone else. And when I installed it, I used Dot 5 silicone fluid for it.
