Advance Adapters 50-5705 - Manual (Page 2)

GM 700R-4 AUTOMATIC TO
TOYOTA TRUCK (21 SPLINES)
GM 700R-4 4 SPEED AUTOMATIC:
This adapter will work on all Toyota 4WD trucks, 1979 through November 1995.
The General Motors 700R-4 has a case length of 23-3/8" and is available in two different engine to transmission bolt patterns.
The case is available with a Chevy bolt pattern that has the top two holes 8-1/4" apart or in a Buick bolt pattern that have the
top two holes 7" apart. 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 these transmissions has 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.
The coupler in this kit is made for a 21 spline male shaft that protrudes from the front of your transfer case. When replacing
transmissions that were equipped with turbo-charged engines, you will need to use a 23 spline coupler in place of the 21 spline
coupler furnished with this kit.
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 either be 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.
If you have a 1989 - 95 electronic fuel injected 4 cylinder. The transfer case shifter linkage was relocated on the 5 speed tailhousing.
The shifter mechanism for both the transfer case and the transmission were one unit. When using this transfer case with any of
our transfer case adapters, you must either modify or replace your transfer case. By changing the shifter rods from a 1984-88
(Carbureted 4 cyl.) transfer case or using Toyota part numbers 36314-35020 (high-low rod) and 36313-35020 (front drive rod), you
will be able to retain your stock transfer case. The other option is to purchase a 1984-88 (Carbureted 4 cyl.) transfer case.

equipment. These manual are normally available at automotive dealerships and parts stores.
