14. After the transmission is bolted to the adapter plate. Make sure that the converter pulls
forward approximately 1/8" for engagement with flexplate. Check the hex head bolt head
for clearance with the adapter plate, and make the necessary modifications if interference
occurs.
15. It is now time for the dust cover. Due to the thickness of the adapter plate, the GM dust
cover will not fit properly. We have found that by taking the GM transmission dust cover
and cutting off the section that extends upwards to the crank, the cover fits fine onto the
transmission (
See Picture 15
). This does leave the flywheel exposed, however, the
flywheels we sell are solid and this should prevent any foreign objects from entering into
the bellhousing.
16. Install the front drive lines. We recommend a B & M sport shifter linkage for the new
transmission, and a Lokar flexible filler tube.
17. If the vehicle is on a lift the front drive shaft will be very close to the engine exhaust pipes.
Be sure to check for clearance before finalizing your conversion.
18. A kick down cable bracket will need to be fabricated to fit your AMC block.
19. Fill with proper transmission fluid.

The dust cover should be cut along the taped line.

13. Before installing the transmission to adapter plate, the transmission must have a couple of
modifications. The ears of the transmission should be removed. The passenger side is
removed for starter clearance. The driver's side can provide adequate exhaust clearance.
The two bolt holes below the GM dowel pins on your transmission must also be modified.
The AMC dowel pin hole and GM bolt hole overlap. The early style adapter plates rotated
the transmission to fit both patterns. However, this caused crossmember and transfer case
problems. The new special dowel bolt that secures the 716138-PLT to the AMC block now
has a 5/16-18" hole drilled and tap in it. This is to fit the GM
bolt hole without rotating the transmission. The overlap-
ping of the bolts mentioned above is not exact; therefore,
to fit the 5/16" bolt to the center of the special dowel pin
bolt, the transmission bolt hole must be opened up to allow
access. We suggest using a rat tail file to elongate the two
bolt holes under the GM dowel pins. Trial-fit the transmis-
sion until the 5/16" bolts fit the special dowel bolt. Two flat
washers have also been provided allowing proper surface
contact for these 5/16" bolts. You will have to grind some
material off the sides for this washer to fit properly toward
the transmission. We do not modify these washers in-
house due to some variations on the different GM trans-
missions. Once these modifications are made, secure all
fasteners from the GM transmission to the 716138-PLT.
Torque the 5/16" bolt 15 ft/lbs with Loctite.
CAUTION: It is extremely important that you properly install the torque
converter, torque converter spacers, and flexplate as specified in the
Advance Adapters instructions. Failure to follow these instructions will
create severe damage to both the transmission and transmission converter.
If your installation does not have the proper converter location, you should
contact our sales department for further instructions.
