Jeep JL, D478 manual 6 speed to Atlas 2sp: The manual transmission used in the JL will require the same adapter housing as the automatic with the same shifter components P/N 50-9901. The Jeep JL with the manual 6 speed is coupled to a Magna transfer case. This is the first year Jeep went away from its standard circular bolt pattern when coupling these two gear boxes. So this required us to manufacture a new adapter housing to couple the Atlas to the manual transmission. P/N 50-9901 adapts to a Atlas 23 spline standard input. The 7.75" adapter also provides the needed length to keep the transmission close to the stock location.
