There you have it! A chronological history of transmissions for Jeeps (for you history buffs out there). Nearly every year new transmissions or improved older designs hit the market, and there is no reason to expect that currently available transmissions will not be discontinued at some point. However, hopefully there will be plenty of used re-buildable transmissions to supply our Jeeps as they age.

So remember...whether you are "shifty" or "shiftless"...keep on Jeepin' with pride.
