used with GEN III or GEN IV V8 engines.

the Jeep flexplate can be purchased from
your Chryser dealer under P/N 52118257

4.0L NOTE:

This adapter is the 3rd design. The first adapter plate was a 1/4" thick. Due to some starter flexing problems, we increased the thickness
of the adapter to .450". This stopped the problem of starter flex. However, we still were having problems with other aspects of the kit
such as starter nose cone clearance, rotated bolt pattern & torque converter bolt head clearance. The new adapter or current production
plate is .625" thick and has been re-manufactured to offer the easiest type of installation. There are still some modifications required;
however, these are minor compared to the two previous designs.

This kit will not work with a 4.0L unless a Sensor kit is installed. We offer two kits to fit the 4.0L engines
either 716138-M or 716138-N. These kits do require you to modify your GM bellhousing for the sensor to
fit through the bellhousing.

This adapter kit fits GM transmissions to Jeep engines. The original design of the adapter was for people that had the original Jeep
TH400 transmission with an AMC pattern. Due to front drive shaft problems, the special Jeep AMC case was often damaged. Since
there are no replacement cases available, an adapter was necessary for using a GM TH400 case. On these particular installations, you
will already have an existing flexplate that works with the TH400 converter.

When we began to sell the replacement adapter for the TH400, we found that these same adapter plates could be used with TH350 and
700R-4 automatic transmissions. These applications will require a stock flexplate for the AMC engine that is being used.

If you are using a 700R-4 automatic transmission, the torque converter bolts will need to be P/N 720073. If a TH350 or TH400 is being
used, then P/N 723777 bolts should be used for the torque converter.

The torque converter adapter is designed to use the stock torque converter holes on the AMC flexplate. We have seen two different
bolt patterns on the stock flex plates. Our adapter ring is drilled for both of these patterns. One pattern is symmetrical and the other
is not, if all of your torque converter bolts do not line up properly, you may need to rotate the adapter ring 90 degrees until the all the
hole do line up. For Jeeps 1988 to 2005 the Jeep flex plate is Jeep part number 52118257. P/N 723777 should be used for the flex plate
to the adapter ring.

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.

CHEVY TH350/700R AUTO TRANSMISSION TO

JEEP 4.0L, ENGINE BLOCKS NEW STYLE

INSTALLATION INSTRUCTIONS:

This adapter will enable you to replace the expensive and hard-to-find Jeep TH400 case with the popular Chevy & GM
transmissions, or adapt the TH350 & 700R to the AMC engine. This adapter kit is not compatible with the Buick, Oldsmobile
or Pontiac TH400 transmission cases. All studs, bolts, washers, converter adapter, adapter plate and converter bolts are
furnished in this kit. The kit does not include a flexplate. Please read the following instructions prior to starting the job. If
there is anything in question, please feel free to contact our sales department at Advance Adapters, (1-800-350-2223).

CAUTION:

It is best to first install the adapter plate onto the back of the engine and inspect the clearance between the
flexplate and steel adapter ring. Due to variations by the flexplate manufacturers, we have encountered
some variations that will require minor clearances on the new steel adapter ring. The adapter plate should
also be test fitted to the AMC engine, and the tunnel/firewall clearance should be checked and modified as
necessary.

1. Remove the original transmission, transfer case & dust cover plate.
Clean the rear of the engine block from all grease and dirt.

2 . Remove the transmission dowel pins from the back of the AMC engine block.
3 . Remove the old pilot bushing from the engine crank. This can be performed

by using a 7/16" bolt and working it back and forth inside the pilot bushing.

o

4 . Your stock AMC dust cover plate and the Advance Adapters adapter plate should be installed

to the back of the AMC block using the two dowel aligning bolts.

5 . Insert the 2 special washers and dowel bolts where the original AMC dowel pins were removed.

Torque to 30ft/lbs with Loctite. These 2 bolts act as new dowel pins for aligning the adapter
plate to the AMC block.
