I don't know either Joe, having repaired my own K46, I had ordered the recommended sealant ahead of time from Tuff Torq along with the parts, maybe one of the guys who have worked on these as well in the past will be along with some advice on what would work otherwise than the TT sealant, good luck in your endeavor and hope the fluid change improves your transaxle performance. If you have'nt already, there is helpful information on this in the JD stickies section :fing32:.
