Installation Instructions
INS0030 Rev. 07/26/13 RPD 05/23/14 Page 1 © 2007 Lokar, Inc.
General Installation Notes:
Please read instructions completely before beginning installation. If
you have any questions please call.
Before starting installation, use wheel chocks to block the vehicle's
wheels. Disconnect the negative battery cable before beginning
installation.
The Ford AOD Selector Shaft, Flange and Arm also requires installation of a
Lokar Kickdown Kit, available separately.
Refer to Fig. 1 and Fig. 2 for the component names.
NOTE: It will be much easier to install this product before the transmission is
installed in the vehicle, if possible.
The AOD (non-computer controlled) transmission has a Throttle Valve
(T.V.) shaft that passes through the center of the selector shaft. Parts
of these instructions and some of the photos will refer to the T.V. shaft,
a T.V. lever, and a T.V. spring.
These parts are not present in an AODE or
4R70W transmission.
Step 1: Put the transmission in Park by rotating the original trans arm
clockwise as far as it will go.
Step 2: AOD Only: Remove the nut and T.V. lever from the T.V. shaft in the
center of the selector shaft.
AODE and 4R70W Only: Remove the bolt or nut from the center
of the selector shaft, and remove the original trans arm.
NOTE: If
the new Lokar flange fits on your existing selector shaft, it is not
necessary to replace the selector shaft. If you are only installing
the Lokar Selector Shaft Flange and Arm and are not replacing the
selector shaft, skip to
Step 13.
Step 3: Drain the transmission fluid and remove the transmission pan and
filter.
Step 4: Remove the 1/8" diameter roll pin that is located just inside the
pan rail on the boss that the selector shaft slides through. The pin
protrudes about 1/8" beyond the boss. Use a pair of side cutters
to grab the roll pin and pry the pin out using the case as your
leverage point.

Step 5: Remove the roller spring that holds the gear selector plate in each
gear position. Fig. 4
Step 6: AOD Only: The T.V. spring keeps tension on the T.V.
shaft. Make sure you pay attention to how this spring
is positioned, in the event that the spring moves
during selector shaft removal.
Fig. 5.
All: Move the gear selector plate all the way to the
rear to put it into low gear. Hold the gear selector
plate with a box end wrench or other tool to keep it
from rotating, and unscrew the 14mm nut from the
end of the selector shaft. On the AOD transmission,
the nut will still be retained by the T.V. shaft and will
remain in the transmission.
Fig. 6 and Fig. 7
Step 7: AODE and 4R70W Only: Remove the Auto Trans Gear
Position Sensor from the outside of the transmission
case by removing the mounting bolts and sliding it off
of the selector shaft.
All: Remove the old selector shaft from the transmis-
sion by sliding it out of the bore. The gear selector
plate will stay in the transmission, and you may have
to tap on it or lightly pry on it to get it separated from
the selector shaft.
Step 8: Lubricate the selector shaft seal in the transmission
and the new Lokar selector shaft with a small amount
of transmission fluid or transmission assembly grease.
On the AOD only, also lubricate the T.V. shaft seal
that is inside the new selector shaft.
DO NOT remove
the T.V. shaft seal; it is not necessary to remove it for
installation of the selector shaft.
Slide the Lokar selector shaft into the transmission.
On AOD models, the T.V. shaft fits inside the selector
shaft.
Step 9: Align the two flats on the gear selector plate in the
transmission with the flats on the new selector shaft,
and install the selector shaft into the gear selector
plate.
Fig. 8 The gear selector plate has a pin attached
to it that must be positioned in the groove on the pis-
ton that protrudes from the valve body. This pin needs
to be in the groove before the 14mm nut is tightened.
Fig. 9 Once the pin is in the groove, tighten the nut.
AOD Only: If the T.V. spring slipped out of place, put
the spring back into position as shown in
Fig. 5. Also
verify that the internal T.V. lever is aligned with the
T.V. piston. With the external T.V. lever removed, it is
possible for the T.V. shaft and internal lever to slide
in too far, and the lever can get trapped between the
T.V. piston and the valve body.
