AOD TV CABLE ADJUSTMENT
Submitted by FLA-LSCSE / 08-14-05
 |
Introduction
The AOD transmission (in almost all Lincolns from the 1980s) may feel
like it is shifting at the right time when the TV cable is actually way
off! The transmission will work for a while and then FAIL! Because of
this it is critical that you learn to set the TV properly.

Directions for Block Type
Cable:
- Pull/push TV cable and block assembly out of throttle arm rubber
grommet.
- Have someone floor the accelerator pedal from inside the car.
While the pedal is floored, push on the throttle body arm to
make sure it's bottomed (wide open) against its stop. (Adjust
throttle cable, if necessary.)
- Push the locking tab up through the adjustment block, with
a pocket screwdriver, so that the locking tab is standing up
next to clevis pin as shown in the picture.
- While someone is holding the throttle pedal floored: Pull the
cable rail HARD towards the end of the cable with one hand, at
the same time engage the clevis firmly into the throttle arm
grommet. Engaging the clevis automatically locks the tab by pushing
it into the block.
- Pull the block adjustment assembly out of the grommet: Make
a mark, on the rail, with a hacksaw blade or knife up against
adjustment block. This is the MAX TV mark.
- Make another mark 5/16" from the max mark out on the rail.
(Use a 5/16 pan bolt for a gauge.) This is MIN TV mark.
- Make another mark midway between MAX mark and MIN mark. This
mark is average or MID-mark.
- Unlock the adjustment tab. Set on MID-mark and lock tab. (Push
it down into block.) Install into throttle arm grommet and road
test.
Road Test
In manual "3", you must have 3-2 kick-down at 50 mph (passenger
cars)
Test Notes:
For Carburetor and CFI fuel injection models: Seems to work best with
setting between MIN and MID.
For SEFI Port Fuel Injection models: Start with a setting just under
MID.
For SEFI High Output (5.0HO) port injection models: Start with setting
just a hair over MID. |

Directions for Lift Tab Type Cable:
- Lift tab up to unlock adjustment assembly.
- Have someone floor the accelerator pedal from inside the vehicle.
While the pedal is floored, push on the throttle body arm to make
sure it's bottomed against its stop (wide open). Adjust throttle
cable, if necessary.
- While the throttle is floor-boarded, lock the tab on TV adjuster.
- Make scratch with hacksaw blade or knife up tight against the adjustment
assembly. This is the MAXTV mark.
- Unlock the tab and slide housing towards bare cable 5~s" and lock
tab. You can use a 5/16" bolt as a gauge. Make another mark up tight
against adjustment assembly. This is the MIN TV mark.
- Make another mark midway between MAX and MIN. This is MID-mark.
- Adjust to MID-mark CI and road test.

NOTE: Adding TV to attempt to correct pinging, chugging
or lugging won't work. It just causes thumps, bumps
and extra wear. Set the TV so that the shifts are
smooth and not late.
Directions for Rod Type TV Adjustment (older
models)
- Remove the air cleaner. Have someone floor
the gas pedal from inside the car while you bend
the THROTTLE cable bracket until the butterfly
arm bottoms solidly on it's stop.
- Turn the adjustment screw IN until 13 threads
are sticking out the front of the adjuster arm.
(Approx. 7/16")
- Start the engine with the AIR OFF and leave
it OFF.
- While the engine is idling, loosen the adjustment
bolt on the arm on the side of the transmission
with a 13mm socket one full turn. Push the arm
up (towards the top of the vehicle) and gently
tighten the bolt.
- Now go back to the top adjustment and back
off 13 turns.
- Now ROAD TEST. Place the selector in the '3'
position and cruise at 45 mph. Floor the throttle,
you will have no 3-2 kickdown. Turn the adjuster
screw in exactly one turn at a time until you
have kickdown at 45 mph. Then, turn the screw
in 3 more turns. You will be in the middle of
the TV adjustment.
- Now ROAD TEST for shift feel and timing. You
can adjust in or out up to 2 turns to improve
shift quality.
- Replace the air cleaner.
