- Place the gear shift selector into D . The shift lever must be in the D position during linkage adjustment.
- Working at the transaxle, loosen the transaxle lever-to-control cable nut.
- Move the transaxle lever to the D position, 2nd detent from the most rearward position.
- Tighten the adjusting nut to 10-15 ft. lbs. (14-20 Nm).
- Make sure all gears engage correctly and the vehicle will only start in P or D .
The Throttle Valve (TV) linkage adjustment is set at the factory and is critical in establishing automatic transaxle upshift and downshift timing and feel. Any time the engine, transaxle or throttle linkage components are removed, it is recommended that the TV linkage adjustment be reset after the component installation or replacementCarbureted Vehicles
See Figure 1
The Throttle Valve (TV) control linkage is adjusted at the sliding trunnion block.
- Adjust the curb idle speed to specification as shown on the under hood decal.
- After the curb idle speed has been set, shut off the engine. Make sure the choke is completely opened. Check the carburetor throttle lever to make sure it is against the hot engine curb idle stop.
- Set the coupling lever adjustment screw at its approximate midrange. Make sure the TV linkage shaft assembly is fully seated upward into the coupling lever.
- To adjust, loosen the bolt on the sliding block on the TV control rod a minimum of one turn. Clean any dirt or corrosion from the control rod, free-up the trunnion block so that it will slide freely on the control rod.
- Rotate the transaxle TV control lever up using a finger and light force, to insure that the TV control lever is against its internal stop. With reducing the pressure on the control lever, tighten the bolt on the trunnion block.
- Check the carburetor throttle lever to be sure it is still against the hot idle stop. If not, repeat the adjustment steps.

- Disconnect the negative battery cable.
- Remove the splash shield from the cable retainer bracket.
- Loosen the trunnion bolt at the throttle valve rod.
- Install a plastic clip to bottom the throttle valve rod; be sure the clip does not telescope.
- Be sure the return spring is connected between the throttle valve rod and the retaining bracket to hold the transaxle throttle valve lever at its idle position.
- Make sure the throttle lever is resting on the throttle return control screw.
- Tighten the throttle valve rod trunnion bolt and remove the plastic clip.
- Install the splash shield. Connect the negative battery cable and check the vehicle's operation.
- Set the parking brake and place the transaxle shift lever into P .
- Loosen the sliding trunnion block bolt, located on the throttle valve control rod assembly, a minimum of one turn.
- Make sure the trunnion block slides freely on the control rod.
- Using a jumper wire, connect it between the STI connector and the signal return ground on the self-test connector.
- Turn the ignition switch to the RUN position but do not start the engine. The Idle Speed Control (ISC) plunger should retract; wait until the plunger is fully retracted, about 10 seconds.
- Turn the ignition switch OFF and remove the jumper wire.
- Using light force, pull the throttle valve rod upward to ensure the control lever is against the internal stop.
- Allow the trunnion to slide on the rod to its normal position.
- Without relaxing the pressure on the throttle valve control lever, tighten the trunnion block bolt.
- Connect the negative battery cable.
TRANSMISSION CONTROL LEVER
- Position the selector lever in D against the rear stop.
- Raise the vehicle and support it safely.
- Loosen the manual lever-to-control lever nut.
- Move the transaxle lever to the D position, second detent from the rearmost position. Tighten the attaching nut.
- Check the operation of the transaxle in each selector position. Readjust if necessary.
- Lower the vehicle.
