AXOD Throttle Cable Fix and Adjust
Throttle valve adjustment error is the most common cause of failure and re-repair
on an AXOD transmission.
If you're happy with how the throttle valve is working install two hose clamps
on the axle housing tightly against the adjuster. You are finished.
If the throttle is hard to push and the transmission has no upshifts, or late
hard shifts, the system has probably defaulted to "Fail-safe". The
following will get it working again and keep it working right:
- Turn off the engine.
- Insert snap ring pliers along side the flat on the shaft and open the wedge lock. With the other hand push the cable housing and heft towards the bare cable 1/2'' or more. (Decrease direction.)
- Have someone floor the gas pedal from inside the car. While the pedal is floored bend or adjust the injector cable bracket until the injector throttle arm bottoms solidly against its wide open stop.
- Install a hose clamp on the shaft. It's OK to move the shaft to make room for the clamp. Tighten it on the shaft and then loosen it slightly so it will slide back and forth.
- Insert snap ring pliers: Open the wedge lock and slide the shaft away from the bare cable as far as it will go.
- While you push the snout away from the bare cable, have someone floor the throttle from inside the car. As the throttle pedal is pushed the shaft will ratchet through the wedge lock towards the bare cable. The reason you are pushing against it is to prevent it from over-jumping through the notches.
- Max points are now all adjusted. Make a pocket knife mark on the shaft against the wedge lock. This is the max TV mark. Slide the clamp against the adjuster and tighten it.
Road test. Remember: The clamp is keeping the TV adjusted to absolute max,
which may be too much. On the road test, use snap ring pliers and a screwdriver
to adjust TV.
To reduce TV: Loosen the clamp and slide it away from the adjuster 3/32" .
insert snap ring pliers to open the wedge lock and slide aft towards the bare
cable. Still too much TV? Do it again.
