GM is in the process of redesigning the trans lines for the Allison transmissions. At least this is what the service managaer at my local GM dealership has told me and there going to replace mine under warranty since mine have been replace twice under warranty and they started to leak again. I'll post again when there on the shelves to buy.

One of the lines on my pulling truck was leaking at the adapter end when I pulled the transmission last fall. Never gave it much thought and didn't realize it was a common problem.
