GENERAL INFORMATIONGENERAL INFORMATION

GENERAL INFORMATION

GENERAL INFORMATIONGENERAL INFORMATION

JEEP 727 & 999 TORQUEFLITE:

This adapter plate is designed for exclusive use on AMC Torqueflite transmissions manufactured from 1980 & up. The
transmission being used must have been previously installed with a 6 cylinder engine. Vehicles that were previously

equipped with a 4 cylinder engine or 2.8 V6 will

between 1973 through 1979, but without modifications. This kit is not compatible with these transmissions. This kit
will work on both the larger 727 transmissions and the smaller 999 & 904 transmissions. It will be the customer's
responsibility to make any necessary adjustments required for the torque converter spacing. We have included a torque
converter spacer and crank support bushing that will fit most applications. IN ORDER TO AVOID TRANSMISSION

DAMAGE, THE CUSTOMER MUST VERIFY THE CORRECT CONVERTER LOCATION.

The difference between the 727 and the 999 transmissions is in the size of the bolts that hold the converter to the
flexplate. We have provided 3/8"-24 NF bolts for the 999 transmissions 1980-1991, 5/16"-24 NF for the 727
transmission, and 8mm-1.0 bolts for 1992 & newer 999 transmissions. These bolts must be used with flat washers
and thread retainer.

and stock flexplate. The measurement is
taken from the transmission side of the flex­plate to the back of the engine block. Our
adapter kit will make the GM block look
basically the same as the this AMC setup. It
will also give you approximately the same
measurement.

2. The adapter plate can now be bolted to
the new engine. Be sure to use the stock GM
dowel pins for alignment between the adapter
plate and engine block. The two stud bolts that
are provided must be installed into the engine
block just below the two stock dowel pins.
After the adapter plate is installed, the lock
washers and nuts can then be installed through
the small access slot.

Due to the close proximity of the AMC and GM bolt patterns
on our adapter plate, you will be required to adjust two holes
on your stock transmission. The two holes in the transmission
bellhousing (photo below) will need to be elongated slightly
with a rat tail file to match our adapter plate.

Two special dowel pins have been furnished for aligning the
transmission to the adapter plate. These dowel pins provide must
be installed into the Torqueflite transmission. These pins have a
slight diameter change of only .003". The larger diameter must be
lightly tapped into the transmission case ( care should be taken to
tap these in as straight as possible. The small end of the dowel pin
will protrude out of the case for indexing into the our adapter plate.

The new Vortec flexplate needs to be installed onto the recessed .400”
engine crank, This flexplate has been modified to include the standard
TH350, 700R and TH400 torque converter holes. The flexplate is dished to compensate for the recessed crank. A new
crank support bushing has also been included to compensate for the Vortec crank location. Once the bushing is installed
the new aluminum torque converter ring will index into the bushing.

The 6.0 engine with cast iron heads and the 4.8 engine coupled only to a stock manual transmission in 1999 to 2003 do
not have the recessed crank. Your stock flexplate must be modified on these blocks.
