Description

Introduction:

The JK control module is the only way of keeping all the stock
functions operational when upgrading to an Atlas transfer case.
This Module lights the dash lights in both high and low range as well
as the settings on the ESP when in 4WD and lockers and swaybar
disconnect on the Rubicon models. This kit is designed for the Atlas
2 speed but can be used on a 4 speed by connecting a additional
low range switch to the planetary housing and splicing that switch
into the lead from the low range switch from the Atlas case.

** Note**

2012 and Up Jeep JK Autos:

JK 2012 and newer Jeeps equipped with an au-
tomatic transmission will also require a Trans-
mission 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 programer like a A.E.V. Procal or
the Bully Dog with the transfer case ratio option
in needed and we sell both of these programers.
Unfortunately, the Atlas 4 speed is not an option
in these newer JKs with the automatic.

The exact ratios for the Atlas are required for re-
programming 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 2.087:1, 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.

OPTIONAL ITEMS:

24-AEV PROGRAMER
24-40440 BULLY DOG
