Hmm, never seen a number that I remember. Maybe when someone posted up a list of Chrysler numbers for Jeep stuff including the fluids, they had a number listed? Just don't remember any.
I suppose you could call a Jeep dealer and ask them for the trans number fro a what, '05 Wrangler maybe? But if they made running changes along the way to improve things, it might be prudent to find the last year it was available and use that part number in case it was different for each.
Good luck. Hopefully someone has already gone through this and will post up their findings.
