WARNING
It is possible for the manual transaxle to become locked in two gears at once. This will occur if the interlock blocker on the gearshift selector lever has spread apart. The result of operating like this will be clutch failure at the least, and driveline failure at the worst. To correctly diagnose the problem, the interlock should be checked using the following procedure:

  1. Disconnect the shift linkage operating lever from the transaxle selector shaft.
  2.  
  3. Remove the transaxle detent spring assembly and selector shaft boot.
  4.  
  5. Remove the aluminum selector shaft plug.
  6.  
  7. Place the transaxle in neutral and pull the selector shaft assembly out of the case.
  8.  
  9. Measure the interlock blocker gap A , in the accompanying picture. If gap A exceeds 5 / 16 in. (8mm) replace the gearshift selector shaft assembly.

  1. Apply a thick coating of chassis grease to the selector shaft shoulder at the threaded end, then insert the shaft through the oil seal. Reverse steps 1-4 to install. Adjust the shift linkage.
  2.  

A-460 Models
  1. From the left side of the car, remove the lockpin from the transaxle selector shaft housing.
  2.  
  3. Reverse the lockpin and insert it in the same threaded hole while pushing the shaft into the selector housing. A hole in the shaft will align with the lockpin, allowing the pin to be threaded into the housing. This will lock the shaft in the 1-2 neutral position.
  4.  
  5. Raise and support the vehicle on jackstands.
  6.  
  7. Loosen the clamp bolt that secures the gearshift tube to the gearshift connector.

  1. Make sure that the gearshift connector slides and turns freely in the gearshift tube.
  2.  
  3. Position the shift connector assembly so that the isolator is contacting the standing flange and the isolator rib is aligned front and back with the hole in the block-out bracket. Hold the connector in this position and tighten the gearshift tube clamp bolt to 14 ft. lbs. (19 Nm).
  4.  
  5. Lower the car.
  6.  
  7. Remove the lockpin from the selector shaft housing and install it the original way in the housing.

A-465 and A-525 Models
  1. From the left side of the car, remove the lockpin from the transaxle selector shaft housing.
  2.  
  3. Reverse the lockpin and insert it in the same threaded hole while pushing the selector shaft into the selector housing. A hole in the selector shaft will align with the lockpin, allowing the lockpin to be screwed into the housing. This will lock the selector shaft in the 1-2 neutral position.
  4.  
  5. Remove the gearshift knob, the retaining nut and the pull-up ring.
  6.  
  7. Remove the attaching screws and remove the console.
