GM 700R-4 4 SPEED AUTOMATIC:
This adapter will work on all Toyota 4WD trucks, 1986 through November 1987 with a R151F transmission.
The General Motors 700R-4 has a case length of 23-3/8". The rear side of the transmission case should have a square bolt pattern
that uses 4 bolts. There are several various lengths of output shafts that the transmissions have been furnished with. You must
make sure the proper shaft has been installed into the transmission for use with our transfer case kit. The speed-o-meter gear
is normally located in the tailhousing, but when adapting it to the transfer case, the location will change to the back side of the
transfer case. The rear transmission support is located in the main case just forward of the tailhousing connection. This can
be used for supporting the crossmember on some installations, but most of our kits provide support on the new adapter housing.
Make sure the bearing retainer clip found on the front side of some transfer cases is removed prior to assembly of the new
adapter. This clip was used to retain lover bearing in Toyota transfer case.
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 we have allowed for; and when coupling into
our new spud shaft, we find a small amount of interference. The adapter housing and coupler must be assembled to the back
of the transmission without interference. DO NOT FORCE THE NEW TAILHOUSING ONTO THE TRANSMISSIONS.
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 a new square-type "O"-ring seal to prevent
fluid leakage. This seal is a stock GM item that is used on all installations.
All installations will require the use of a transmission cooler. The cooler can be either installed in the radiator or a remote location
is acceptable. The transmission shift control can either be a Hurst floor mounted type shifter or sometimes the existing column
shift can be modified on certain applications.
The linkage on the Toyota transfer cases will vary. Some have the control lever on the tailhousing of the transmissions while
others have it on the transfer case. This adapter can be used with either style. If the opening is not used on the top of the new
housing, you will need to cover the square opening with the cover provided.
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 changed that will be required to complete your

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 manual are normally available at automotive dealerships and parts stores.
