NOTES

1 . This adapter is designed for exclusive use of the 4WD GM version New Venture Model 4500 transmission. You must

use this transmission due to the spline area where the GM harmonic balancer is located. The shaft must be shortened
to 4.498" long which will be directly behind the 31 spline area. In order to cut off the shaft, you will need to remove
the tailhousing. The shaft can be cut off using an abrasive cut off saw or a skill saw equipped with a special metal
cutting blade. Be sure to use safety glasses during this procedure. You must remove the harmonic balancer and install
the 2 piece set collar.

2 . Bolt the new larger tailhousing to the back of the transmission. Make sure all of the gears clear the new housing and

the dowel pins are used. Assemble the plate to the transfer case. Make sure the cut out for the transfer case linkage
will allow the necessary clearance for your shifter control.

3 . The bolt pattern on the front side of the New Venture gear box is unique to only late model GM transmissions. The

original GM bellhousing provides a slave cylinder on the passenger side of the vehicle that will interfere with the early
GM front driveshaft. We have a new aluminum bellhousing that will have this bolt pattern provided for all Chevy
V8 conversions.

4. The NP205 transfer case must be equipped with a 10 tooth male input spline as illustrated. This shaft is common
to all GM NP205 transfer cases used with the manual truck 4 speed transmissions. The original input shaft required
a special seal on the outside diameter. Install the new sealed bearing into the front of the NP205 transfer case and
install the oil seal into the adapter housing (casting number 51-0205). This will prevent the transfer of oil between
the two gear boxes. You will also be required to use some RTV blue silicone on the splines of the transfer case side
of our coupler. Unless this is done, the coupler shaft we manufacture will allow fluid to transfer down the splines
into the transfer case. ONLY Apply silicone to the inside of our coupler and to the transfer case side of our coupler.

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.

As you slip the coupler over the splines, the silicone will fill the voids on the splines. We also recommend that you
take the excess silicone that should have squeeze inward towards the center of the coupler and smooth it out with
your finger. This will seal the splines to avoid oil transfer. Let the silicone dry for 6 hours before installing the
transmission to minimize the chance of silicone getting into the NV4500 tailhousing.

Make sure both gear boxes have vents to prevent gear-generated pressure.
