NOTE: This kit requires the 2WD output shaft
to be shortened. If you are using this kit on a
newer hex bolt pattern 4L60E transmission, then
you will be required to use our 51-0405 adapter
housing. Please note that the cut off location on
the output shaft must be made after this adapter
is installed on the transmission. This 51-0405
adapter make the hex pattern 4L60E transmission
look just like the square bolt pattern transmis­sion, and the cut off location for the output shaft
is shown on this instruction sheet is for the square
bolt pattern transmission.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components will
void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly recommend
that you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components. We recommend that
a service manual pertaining to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment. These manuals are normally available at
automotive dealerships and parts stores.

INSTALLATION INSTRUCTIONS

This kit is for the GM 700R-4 4 speed automatics to all Toyota Land Cruiser transfer cases, 1974 through August 1980.
The design of this kit is based off of a 2WD 700R4. The 2WD output shaft must be cut to the length as illustrated on Page

3. As a courtesy, we have supplied a complimentary 2WD shaft that has been cut to the proper specification. Once your
2WD output shaft has been cut or the supplied shaft has been installed, the new Advance Adapters spud shaft can now
be put into position. The new spud shaft should be pressed onto the new rear bearing so the external snap ring is towards
the threaded end of the shaft. The spud shaft and bearing can now be installed from the transfer case side of the adapter
and pressed into the bearing recess. The snap ring that is on the outside diameter of the bearing will keep the shaft in the
proper location. You can examine the transfer case face to see the slight snap ring recess that will trap the bearing snap
ring and establish the correct location.

The adapter kit is provided with two adapter housings. When bolting these castings together, use the square "O"-ring
between them to seal properly. The 4 metric bolts are provided to secure the adapters to the transmission. Due to the
extreme length of this transmission and adapter, driveshaft modifications will be required on almost every installation.

On Toyota Land Cruiser conversions, you will find that the overall assembled length of the new transmission and adapter
will not fit between the original rear crossmember and the radiator, the relocation of the tubular mount will be required.
We suggest that the rear drivetrain be supported by a crossmember underneath the adapter. We offer a new crossmember
assembly that includes the 716003 rubber mount for supporting your transmission assembly. The new crossmember
assembly is Part No. 716004. The right side of the adapter has two tapped holes to assist you in mounting a transfer case
linkage bracket for support of your pivot stud.

GM 700R-4 4 SPEED AUTOMATIC:

When installing the new transfer case adapter, make sure that the coupler and the output shaft do not bottom out. We
have found on occasion that a transmission output shaft may be slightly longer than what we have allowed for; and when
coupling into our new spud shaft, we find a small amount of interference. The adapter housing and spud shaft must be
assembled to the back of the transmission without interference. DO NOT FORCE THE NEW TAILHOUSING ONTO

THE TRANSMISSION. If assistance is needed, please feel free to call us on our toll free number, (800)-350-2223.

When assembling the adapter housing to the transmission case, we have provided you with a new square type "O"-ring
seal to prevent fluid leakage. This seal is a stock GM item that is used on all 700R-4 installations. On most installations,
a slight pan modification may be required for clearance of the front Universal yoke.

The overall adapter thickness is 6-3/4". The reason for this extremely long adapter length is to provide the necessary
clearance for the front output shaft yoke around the 700R-4 oil pan. We have found on occasion that vehicles equipped
with the larger yoke may have to change to the smaller yoke, or slight modifications to the oil pan may be required. For
additional front driveshaft clearance, we also recommend kit P/N 716370 (course spline kit) or P/N 716371 (fine spline
kit). These kits are a modified front yoke and slip yoke assembly that will provide the additional clearance.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components will void any
possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly recommend that you contact
our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components. We recommend that a service manual pertaining
to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment. These manuals are normally available at automotive dealerships and parts stores.
