JL & JT CABLE SHIFTER ASSY. ATLAS 2SP
The shifter bracket and cables need to be installed to the front of the Atlas before the unit is installed into the vehicle. The stock transfer case, shifter and cable will also need to be removed.
Th Atlas shifter is designed to be installed quick and easy without having to adjust the cable to obtain proper shifting of the Atlas.
When installing an Atlas into a JL you will need a computer interface for the drivetrain low range switch. P/N 300377A .
JL and JT 2018 & newer Jeeps equipped with an automatic transmission will also require a Transmission Control Module flash to operate correctly with the new Atlas transfer case. Jeep coded the stock transfer case ratio of either the 2.72:1 or the 4.0:1 into this module and any different ratio in the transfer case will put the vehicle into a limp mode. A Jeep programmer like a Z Automotive or the Vgate OBD2 code reader with the Canbus phone app from jscan, work great. The exact ratios for the Atlas are required for repro-gramming the module. We round up or down to the decimal on our ratios; however, the Jeep computer module will accept the three places right of the decimal. The ratios are as follows: 2.0:1 is exactly 2.11:1, 3.0:1 is 3.030:1, 3.8:1 is 3.824:1, 4.3:1 is 4.286:1, and 5.0:1 is 5.048:1.
The 300377A is included in the Atlas pre-configured units Atlas JL
