Torque Converter
Installation Instructions
Installation of a Torque Converter is not always as easy
as it seems. It has come to our attention that as many as
85% of all Torque Converter warranties have been traced
directly to improper installation. Therefore, we strongly
recommend that you read these instructions and follow
them carefully to avoid any unnecessary problems due to
improper installation.
Step 1
Once you have removed the converter from the box,
please take a minute to make sure that it is the correct ap-
plication. To do this, hold the converter onto the flywheel
to check that the converter pilot fits properly into the
rear of the crankshaft with no excess clearance. Check to
make sure that the bolt holes or studs on the converter
line up with the bolt pattern of the flywheel.
Step 2
After checking the converter for fit to the flywheel and
crankshaft, check the flywheel itself for cracks or exces-
sive wear on the flywheel starter teeth. We strongly
recommend that you replace your stock flywheel with
a heavy duty flywheel. They are available for almost all
applications.
Step 3
When installing the converter onto the transmission,
pour approximately one quart of ATF into the converter
before installing into the transmission. Using a light
grease, coat the transmission seal, front pump bushing,
and the pump drive hub of the converter.
Step 4
Install converter into the transmission carefully to
prevent damage the front seal and bushing. Once you
are into the pump, hold the pilot of the converter with
one hand to center the converter, and rotate the front
mounting pads in a clockwise direction. This will allow
the splines and hub slots (or flats in the case of Ford type)
to engage into the pump properly. You should experi-
ence two distinct drops of the converter into the trans-
mission before it is all of the way in. At this point use a
light lithium grease (white) or equivalent and grease the
torque converter pilot and crankshaft pilot so that the
converter slides without binding.
Step 5
Before installing the transmission to the engine make
sure that the engine dowel pins are free of rust, and that
the dowel holes in the trans are free of dirt and corrosion.
Grease both lightly to avoid any type of bind-up. NOTE:
If you are using a motor plate, make sure that your dowel
pins are long enough. In the case of a 0.090" thick mid-
plate, you can use the stock engine dowel pins. Motor
plates thicker than 0.090" will require longer dowel pins.
Step 6
Locate the transmission onto the engine dowel pins
and install transmission mounting bolts. The transmis-
sion housing should contact the engine block squarely.
DO NOT attempt to draw the transmission against the
block with the bolts. The converter is probably not all of
the way into the transmission. (Refer to Step 4).
Step 7
After the transmission housing bolts are tight, check to
see if the converter can turn freely (Ford applications with
studs should have slight movement within the flywheel
mounting holes). Push the converter into the transmis-
sion as far as possible. Using a ruler or scale, check the
distance between the converter pad and the flywheel
as shown in Figure 1 (see reverse side). Pull converter
forward a minimum of 1/8 of an inch, maximum 3/16 of
an inch. Using flat washers, remove any additional space
between the converter and flywheel. NOTE: In case of
Ford applications with studs, measure from end of stud to
flywheel. Tighten converter nuts and measure again. The
difference should be within the tolerance.
Step 8
Finish the installation of the transmission. When fin-
ished install four quarts of ATF in the transmission. Start
the engine and immediately add two more quarts. Now
you can add additional fluid to fill the transmission. At
this point please read our section of filling the transmis-
sion.
