TOYOTA L/C TRANSFER CASE TWIN STICK
INSTALLATION OF PART #715585:
This kit requires the installation of a new mode selector shaft into your stock transfer
case. This shaft can be installed with the transfer case still in the vehicle. The mode
shaft is installed into an aluminum housing that is bolted to the front output shaft
housing of the transfer case. This mode shaft housing bolts on using (4) 12mm bolts.
By removing these bolts, the mode housing can be removed from the transfer case.
Set the mode housing on a bench and remove the plug bolt to expose the bolt that
couples the shift fork to the mode shaft. Remove the shift fork bolt through this
access hole. Remove the shifter detent ball and
spring by removing the detent bolt. Remove the
rubber boot from the mode housing and pull the
mode shaft from the housing. Install the new mode shaft through the seal and into
the housing with the detent notches in the correct orientation. Reinstall the shift fork
bolt into the shift fork and new mode shaft. Insert the detent ball, spring and cap into
the housing. Slide the rubber boot back onto the mode shaft. Install the mode housing
back onto the transfer case, making sure to silicone between the surfaces to secure
for no leaks.

TOYOTA L/C TRANSFER CASE TWIN STICK
INSTALLATION
Install the transfer case high/low shifter arm to the top cover of the transfer case. Since Land Cruisers had two shaft
configurations, we have provided two tapped holes on this lever. Match the tapped hole with the flat portion of the shaft.
Temporarily install the pivot shaft and both shift blocks (P/N 715575 & 715577) onto the Advance Adapters bracket. These
two blocks should be pointing straight up at the middle of their range. Paying attention to the orientation of the blocks and
where the stock hole in the floor is located, carefully bend the shift
handles (P/N 715586A) to fit your particular application. Make sure
the handles clear each other as they travel along their path. It may be
necessary at this point to enlarge the hole in the floor to gain clearance
for both handles.
Now weld each handle to its corresponding shift block, as shown.
Mode shift link P/N 715588 comes pre-bent, but the distance it sticks
out of the mode block (P/N 715577) needs to be set for your
application. Weld the mode shift link to the mode block so that it is
in-line with the mode shaft (P/N 715585) and so that the link is parallel
to the long edge of the block (straight down). See pictures “vertical
alignment” and “horizontal alignment” below for a visual description.
Note that the mode shift link may need to be cut on the non-threaded
weld all the way around
end to achieve the desired alignment.

TOYOTA L/C TRANSFER CASE TWIN STICK
After welding is complete, press the bushings (P/N FJ4404) into both shift blocks until they are completely seated in both
the pivot block holes. This would be the best time to paint the two welded handle assemblies. Make sure to mask off the
bushings (FJ4404) so that no paint gets into the inside diameter. Now assemble the pivot shaft (P/N 715579), both handles
(715586 & 715587), the 5-16" flat washer, the 5/16" lock washer, and the 5/16"-18 nut together as a unit. Push the handles
up through the floor and thread the pivot shaft into the side of the transmission.
Now install the two 3/8" jam nuts and ball joints onto the 3/8" all thread and bolt this assembly to the high/low shift handle
and arm. Adjust the length so that the handle is pointing straight up when the transfer case is in neutral. Cutting of the all
thread may necessary to achieve this. Repeat this same process for
the mode shifter assembly using the ball joint, jam nut, and male heim
joint. The male heim joint mounts to the mode shaft with the supplied
clevis pin and cotter pin.
Twin sticks through modified hole in floor.
Once the transfer case shifts in a satisfactory manner, mount the shift
boot over the hole in the floor using the metal ring supplied. Use
approximately 4 self tapping screws to go through the boot, metal
ring, and floor. Finish the installation by adding the 1/2" jam nuts and
the shift knobs.
