4R70W Selector Shaft Flange and Arm
General Installation Notes:
Please read these instructions completely before beginning the installation.
If you have any questions, please call.
Before beginning the installation, disconnect the negative battery cable and
use wheel chocks to block the vehicle’s wheels.
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.
AOD transmission shown in all of the following photos. AODE and 4R70W are similar.
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
Selector Shaft Flange fits on your original selector shaft, it is not
necessary to replace the selector shaft. If you are not replacing the original
selector shaft and are only installing the Lokar Selector Shaft Flange and
Arm, 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.
Fig. 3 If the roll pin has been pushed all the way in previously, you can use
a small drill bit to grab the inside of the roll pin to pull it out.
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 case the spring
moves during selector shaft removal and you have to put it back into position.
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 large 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 original selector shaft from the transmission 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 new Selector Shaft and the selector shaft seal in
the transmission 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 new 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 thetransmission
with the flats on the new Selector Shaft, and install the Selector Shaft into
the gear selector plate. Fig. 8 The gear selector plate hasa pin attached to
it that must be positioned in the groove on the piston that protrudes from
the valve body. This pin needs to be in the groove before the large 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. Fig. 5 and
Fig. 10
Step 10: Reinstall the roller spring that holds the gear selector plate
in gear. Fig. 11
Step 11: Reinstall the 1/8″ roll pin. It will align with the groove in
the Selector Shaft. DO NOT DRIVE THE ROLL PIN ALL THE WAY IN FLUSH WITH THE
CASE! It is mportant that the roll pin is sticking out beyond the casting so
it can be removed if needed at another time. Fig. 12
AODE and 4R70W Only: Reinstall the Auto Trans Gear Position Sensor onto
the Selector Shaft and attach to the transmission case using the original
bolts. Make sure the tabs on the inside of the sensor are aligned with the
slots in the Selector Shaft.
Step 12: Rotate the gear selector plate all the wayforward into the
“PARK” position.
Step 13: AODE and 4R70W Only: Install the new LokarFlange onto the
Selector Shaft. If using theoriginal selector shaft, use the original nut or
boltto retain the Flange. If using the Lokar Selector
Shaft, install the supplied 3/8″-16 x 3/4″ lock boltinto the Selector Shaft to
retain the Flange.
All: Install the trans arm onto the new SelectorShaft or Flange using the
three #8-32 x 3/8″ button head bolts and lock washers. Whenusing a Lokar Trans
Mount, Tail Mount, or FloorMount Shifter with rod-type linkage (not cable
operated), the Trans Arm needs to be installedat approximately the 12:00
position with the transmission in “PARK”. Fig. 13 If using an OEcolumn shifter
(rod type) or a cable-operatedLokar Floor Mount Shifter, the Trans Arm needsto
be installed at approximately the 7:30 positionwith the transmission in
“PARK”. Fig. 14 The Trans Arm may need to be positioned differently to work
with non-Lokar shifters.
The linkage rod or cable from the shifter will beconnected to the 1/4″ round
hole at the end of the trans arm. The 3/16″ diameter hole that is part way up
the arm and next to the slot shouldbe towards the back of the transmission.
This hole is used with a Lokar Shift Indicator Kit.
This selector shaft will work with a variety of other shifters. The slot gives
the ability to adjust the center distance of the shift linkage at the
transmission.
Step 14: AOD Only: Verify that the internal T.V. lever is still aligned
with the T.V. piston. Install the external T.V. lever, following the
instructions that are provided in that kit. This will prevent the internal
T.V. lever from becoming misaligned.
All except Flange-and-Arm only installations:
Reinstall the filter and the transmission pan. Fill with the appropriate
amount of transmission fluid.
Step 15: Double check to make sure all fasteners are tightened properly.
Continue with the installation of the shifter mechanism and/or Kickdown Kit.
