Frank, it looks as though you have a common problem caused by an inadequate factory crimp on the transmission cooling lines.

To change the cooling line, check out the instructions of a guy that has done it before.

Good luck on that.

Note also that on the bottom of the forum thread, the moderator chimes in and mentions that it is covered under warranty.
