Notes:
the spud shaft into the transmission and measure the stick out of the shaft past the adapter plate. The shaft should only protrude
.250" past the adapter which is ok for the Atlas 2 speed and 4 speed.
Notes: This kit is designed to adapt the Atlas transfer case to a Toyota FJ Cruiser transmission. This adapter plate works with
the automatic transmission only. The exhaust that runs under the stock transfer case can remain installed when doing the new
transfer case install; however, we found it was much easier to remove it while installing the transfer case.
The spud shaft in this kit should be checked for it stick out, temporally install the adapter plate to the transmission. Install

Installation: Remove the stock transfer case from the stock tailhousing adapter. Make notes on the bolt location on the stock
tailhousing as these bolts are various lengths and are to be reused when installing the Atlas. The stock tailhousing is retained along
with the stock rubber crossmember support. Once the transfer case is removed, you'll see a seal located in the stock tailhousing.
This seal must be removed and discarded. Some tailhousings also had a bearing which also must be removed. Install the new
oil seal into the large end of the seal adapter. The sealing lip should be facing down. The small end of the seal adapter has the
same O.D. (outside diameter) as the old seal that was just removed from the stock tailhousing. The seal adapter is a press-fit into
the stock tail and should now be installed.Install the new oil seal in its place. The kit comes with a new spud shaft which fits into
the stock Toyota transmission. This spud shaft has a Jeep 23 male spline on the opposite side which fits into a standard 23 spline
Atlas case.
The adapter plate should now be installed onto the Atlas transfer case. The adapter plate indexes off of the Atlas front retainer and
is bolted on with the (6) 3/8"-16 flat head bolts. The stock transfer case had a 40 degree rotation, the new adapter plate can offer
you eight clocking options. All of these options may not be feasible due to transmission clearances and body clearances. On the
prototype vehicle we did, the 40 degree rotation was retained. The Atlas should be test fitted before the adapter plate is secured
to check for Atlas shift rail clearance on the transmission tailhousing; and the Atlas cable linkage should also be test fitted on the
unit to check for the same clearance issues. Once these areas of concern are checked, check for any necessary clearances. The
stock tailhousing and adapter plate may require clearance on some rotations. The adapter plate should be installed. The bolts and

bolt holes should be cleaned, red Loctited and torqued to 30 ft./lbs.
Once the adapter plate is secured and orientated correctly, you'll now need to couple it onto the back of the stock transmission
tailhousing. The stock tailhousing used two dowel pins to align the stock transfer case to the transmission. These dowel pins must
be retained into the stock tailhousing for proper alignment of the Atlas onto the transmission.
Atlas Shifters:
Clearance on the FJ cruiser for the shifter is very tight on the floorboard as well as the transmission clearance. The photo's below
show the adapter blocks that provide additional clearance for the cables on the transmission. The new shifter block that mounts
to the Atlas will need to be modified like the one in the photo if the link block is used on the front output shaft shift rail.
