KICKDOWN CABLE



  1. Run the engine until the normal operating temperature is reached. Be sure the choke is fully opened.
  2.  
  3. Loosen the adjustment bracket lock bolt mounted on transaxle to engine flange.
  4.  
  5. Be sure that the adjustment bracket can slide freely. Clean as necessary.
  6.  
  7. Slide the bracket toward the engine as far as possible. Release the bracket and move the throttle lever to the right as far as it will go. tighten the adjustment lock bolt to 105 inch lbs. (12 Nm).

A-604 UPSHIFT & KICKDOWN LEARNING PROCEDURE



A-604 Ultradrive Transaxle

In 1989, the A-604 4 speed, electronic transaxle was introduced; it is the first to use fully adaptive controls. The controls perform their functions based on real time feedback sensor information. Although, the transaxle is conventional in design, its functions are controlled by the ECM.

Since the A-604 is equipped with a learning function, each time the battery cable is disconnected, the ECM memory is lost. In operation, the transaxle must be shifted many times for the learned memory to be reconstructed by the ECM; during this period, the vehicle will experience rough operation. The transaxle must be at normal operating temperature when learning occurs.

  1. Maintain constant throttle opening during shifts. Do not move the accelerator pedal during upshifts.
  2.  
  3. Accelerate the vehicle with the throttle 1 / 8 - 1 / 2 open.
  4.  
  5. Make 15 to 20 1st to 2nd, 2nd to 3rd and 3rd to 4th gear upshifts. Accelerating from a full stop to 50 mph each time at the aforementioned throttle opening.
  6.  
  7. With the vehicle speed below 25 mph (40 km/h), make 5 to 8 wide open throttle kick downs to 1st gear from either 2nd or 3rd gear. Allow at least 5 seconds of operation in 2nd or 3rd gear prior to each kickdown.
  8.  
  9. With the vehicle speed greater than 25 mph (40 km/h), make 5 to 8 part throttle to wide open throttle kick downs to either 3rd or 2nd gear from 4th gear. Allow at least 5 seconds of operation in 4th gear, preferably at road load throttle prior to performing the kickdown.

  1. Run the engine until it reaches normal operating temperature.
  2.  
  3. Loosen the cable mounting bracket lock screw.
  4.  
  5. Position the bracket so that both alignment tabs are touching the transaxle case surface and tighten the lock screws.
  6.  
  7. Release the cross lock on the cable assembly by pulling the cross lock up.
  8.  
  9. To ensure proper adjustment, the cable must be free to slide all the way toward the engine against its stop after the cross lock is released.
  10.  
  11. Move the transaxle throttle control lever fully clockwise and press the cross lock down until it snaps into position.
  12.  
  13. Road test the vehicle and check the shift points.
  14.  

6-Cylinder Models
  1. Run the engine until it reaches normal operating temperature.
  2.  
  3. Loosen the adjustment swivel lock screw.
  4.  
  5. To ensure proper adjustment, the swivel must be free to slide along the flat end of the throttle rod. Disassemble, clean and lubricate as required.
  6.  
  7. Hold the transaxle throttle control lever firmly toward the engine and tighten the swivel screw.
  8.  
  9. Road test the vehicle and check the shift points.
