I had my tranny rebuilt last week... asked some of the same questions to the mechanic and got these responses:
In early 90's, Jeeps with 3-spd auto had a bolt-on kit available that put in an overdrive gear. The guy could not find whether this was still available, and believed he "might have heard" that it was never a very good solution. He explained that the 4 speed Jeep's now come with is really a 3-spd overdrive (I'm not sure exactly what that means.)
Sorry this isn't more helpful... I had trouble getting much info in the forum about the auto tranny's, so I hope you have better luck!
