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 has 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 the transmissions have been furnished with and you must make
sure the proper shaft has been installed into the transmission for use with our transfer case kit. 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 in the main case just forward of the tailhousing connection. This
can be used for supporting this crossmember on some installations, but most of our kits provide support on the new adapter
housing.
When installing the new transfer case adapter, make sure that the transfer case input sleeve 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 the transfer case, we find a small amount of interference. The adapter housing and 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, 1-800 350-2223.
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 O-ring seal is a stock GM item that is used on all 700R-4 installations.
This adapter can be used on either Jeep Wranglers 1987 and newer or Jeep Cherokees 1984 and newer. The only difference
is the transfer case shifter linkage. The adapter is 1-1/2" thick and will provide an overall transmission assembly length
of 24-7/8". On conversions using the 700R-4, you can anticipate driveshaft modifications. The adapter crossmember

support is designed around replacement of a manual transmission. If you are replacing an automatic transmission, you
will find that the crossmember support will hang too far down when it is bolted to the bottom of our new adapter housing.
We suggest that you purchase a crossmember support from the manual transmission application to simplify this problem.
The transfer case shift linkage is mounted in two different designs. Jeep Wranglers 1987-96 will require shifter bracket
No. 715523, while Cherokee conversions will require shifter bracket No. 715524. Some applications will the purchase
of a stock jeep bracket #53004280. This is the most universal for YJ Wranglers. TJ conversions will need to space
the body bracket to use the stock linkage.
ASSEMBLY PROCEDURES:
1. The output shaft provided by Advance Adapters should be installed by a an experienced transmission tech.
2. Trial fit the adapter on the transmission. Check to see that the casting seats flush to the transmission case.
3. Trial fit the transfer case to the adapter and transmission. Check for spline engagement, and shaft depth into the
input coupler of the transfer case.
4. If the transfer case does not mate flush against the casting, DO NOT DRAW IT TOGETHER WITH THE
FASTENERS. SEVERE DAMAGE WILL OCCUR. This is not normally found when replacing an AX15 manual
transmission. If interference is detected, the output shaft must be shortened to a flush stickout with reference to
the casting. Automatic Torqueflite 999 applications, where the factory output shaft does not protrude beyond
the stock adapter, will need shaft modifications. Cutting the shaft will require a cut off disc to cut the outer edges
and a hacksaw to cut through the center. If you are unsure about cutting, please call Advance Adapters toll free at
1-800 350-2223. If you do not have the ability to cut your shaft, a 1" spacer is available (P/N 51-0404).
5. Press the seal into the casting with the open side toward the transmission.
6. Install the rubber o-ring on the transmission side of the adapter. A thin bead of silicone should be applied as a sealant.
7. The four 10mm X 40mm Socket Head Cap
Screws are then used to secure the casting to the
transmission.
8. Two rotations are provided on the casting. Choose
the rotation that best suits your application.
9. Studs and nuts are provided for securing the
transfer case.
10. Two of the positions on the rotation will require
removal of two studs from the transfer case and
substitution by the two 3/8"-16 x 1-1/4" Socket
Head Cap Screws. This is due to lack of wrench
clearance around the casting.
11. Use silicone sealant on both sides of the transfer
case gasket. Use Loctite on all bolts.

NOTES:
1. Before assembling the new transmission shaft into your 700R-4, you must verify the spline size of the new shaft and
the input gear of the new process transfer case. The shaft is available in either 21 or 23 spline tooth count.
2. Be sure that the adapter shaft and T/C input gear do not bottom out prior to the adapter meeting flush with the
transmission. Some models may require the output shaft to be shortened.
3. The adapter has provisions for a new seal NAT #456057, the outside diameter is 3.75" and the inside diameter is 1.937".
The seal must be installed with the open side towards the transmission.
