GM 700R-4 4 SPEED AUTOMATIC:

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. The speedometer 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 on the main case just forward
of the tailhousing connection. This can be used for supporting the crossmember on some installations, but most of the
stock casting provide a support on the new adapter housing.

When installing the new transfer case adapter, make sure that the coupler and the output shaft do not bottom out. DO

NOT FORCE THE NEW TAILHOUSING ONTO THE TRANSMISSIONS. If assistance is needed, please feel free to

call us on our toll free number [phone].

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. In order to allow for additional front
driveline clearance, we recommend that the engine and transfer case be offset to the driver's side on vehicles having front
driveshafts located on the passenger's side. On Jeep and Toyota Land Cruiser conversions, this can be approximately
1" offset of centerline.

NOTE: This kit uses the

stock drive sleeve found in
the stock TH350 adapter
housing.

Some of the stock NP205 transfer cases used a large C.V. yoke assembly that may interfere with the 700R transmission
pan. You may be required to replace your transfer case yoke & driveshaft assemblies.

This output shaft can be used with Toyota Land Cruisers, Blazers, Cherokees and Jeep transfer cases 1987 & newer.

DO NOT ATTEMPT to use this shaft on Jeep transfer cases, Model No. Dana 18/20.

The bolts that hold the new adapter to the main case will require a metric thread. We have included 4 new bolts for use
with Jeep, Toyota & Blazer conversions.

When using the GM NP205 adapter you will need to use the longer 720056 metric bolts. These two bolts fit the top two
holes of the stock adapter and provide a better thread contact to the 700R case.
