Thanks guys. I do have a spare AX15 in the garage, just need a bellhousing. I actually was presently surprised by the 6 speed. I do like it with 4.11s and 37s. Not sure how it will behave with 4.88s that are in the new axles that are 8 weeks late from Currie. I'll checkout some trans places and see what they say. Thanks, I figured a Jeep mechanics have the trans guys on speed dial.
