QUESTION: I recently purchased a used dana 20 transfer case,the previous owner said the t case shift pattern is 4H 2H N 2L and 4L is this correct. OZARKJEEPN
ANSWER: Officially the typical pattern in a CJ is 4H 2H N 4L but after time the shift linkage loosens up to allow 2L. The Dana 20 in the jeepfan.com CJ has the pattern you described below even though the shift knob says it the way mentioned above.
Consider it a bonus with age!
