DOWNSHIFT CABLE



British Borg-Warner
  1. Run the engine at an idle until it reaches the normal operating temperature.
  2.  
  3. Adjust the cable by turning the outer cable adjusting screw to a point where the lower end of the screw just touches the stop near the downshift cable end fork.
  4.  
  5. The gap between the stop and the adjusting screw should be between 0.05-0.10mm.
  6.  

If the downshift is still incorrect, the cable must be adjusted with the aid of a pressure gauge. Refer this adjustment to a Dodge dealer or an automatic transmission specialist.

KICKDOWN SWITCH



American Borg-Warner

The kickdown switch is located on the carburetor. When the accelerator pedal is completely depressed and the throttle valve of the carburetor is wide open, the kickdown switch is activated and the kickdown solenoid at the transmission valve body is energized. To check the switch, disconnect the lead wire to the solenoid at the connector and attach it to an ohmmeter. Turn the ignition switch ON and depress the accelerator pedal on the floor. The switch is working correctly if the meter shows a current flow. If not, check the accelerator rod adjustment and re-adjust the switch or replace it.

JM600

The kickdown switch is located on the upper post of the accelerator pedal. With the pedal fully depressed, a click should be heard just before the pedal bottoms out. If not, loosen the locknut and extend the switch until the pedal lever contacts the switch and a click is heard at the proper time.

SHIFT LINKAGE



Borg-Warner

  1. Apply chassis lube to all sliding parts.
  2.  
  3. Place the selector in the NEUTRAL position.
  4.  
  5. Turn the adjusting cam until the distance between the adjusting cam and the selector lever end is 15-16mm.
  6.  

NEUTRAL SWITCH



Borg-Warner

Fig. Fig. 7 Borg-Warner neutral safety switch wiring connector descriptions

  1. Install the switch with the slit mark aligned with the (N) position.
  2.  
  3. If the switch is not properly connected, loosen the attaching screws and adjust its position by moving it forward or backward.
  4.  
  5. The gap between the switch and the lever should be adjusted at 1.5mm so that the switch is free from the lever and turns smoothly.
  6.  
  7. Adjust the connection range of the switch so that in any position, the lever can be moved an equal distance in either direction.
  8.

Fig. Fig. 8 Neutral safety switch adjustment on the TorqueFlite transmission

  1. The inhibitor (Neutral) switch is located at the base of the shift control under the console cover.
  2.  
  3. Loosen the set screw that retains the shift lever handle to the shift lever. Remove the handle.
  4.  
  5. Remove the screws at the top and rear of the console, place the shift lever in L and remove the console. Put lever in P position.
  6.  
  7. Remove the top and side shift indicator panel mounting screws and pull the panel up. The inhibitor switch can now be disconnected and removed if necessary.
  8.  
  9. Adjust the switch by moving the selector lever to the N position. Loosen the mounting screws and adjust the inhibitor switch so that the pin on the forward end of the rod assembly will be in the position near the lobe of the detent plate and that this position will be at the front end of the range of the N connection of the switch. Temporarily tighten the switch mounting screws. After adjusting the selector lever clearance to 1.5mm tighten the mounting screws.
  10.  
  11. To test the switch: Disconnect the wiring connector and set the selector lever in each of its positions. With a continuity tester connected current should be available in the P, N and R positions only. Replace switch if necessary. Install console and shift handle.
  12.

  10.  
  11. Hold the switch in that position and tighten the attaching bolts to 5 ft. lbs.
  12.  
  13. Using an ohmmeter, check the switch across the leads for continuity.

Fig. Fig. 10 JM600 downshaft solenoid location

  1. Raise and support the car on jackstands.
  2.  
  3. Uncouple the connectors on the wiring at the solenoid.
  4.  

Transmission fluid will drain from the hole after the solenoid is removed. Have a drain pan ready to catch it.

  1. Remove the solenoid and O-ring.
  2.  
  3. Connect a 12V source across the solenoid wires to verify that the plunger is operational. If not, replace it.
  4.  
  5. Apply a coating of clean transmission fluid to the O-ring and install the solenoid. Fill the transmission.
  6.  

THROTTLE ROD



TorqueFlite

Fig. Fig. 11 Torque flight throttle rod and linkages

Warm the engine until it reaches the normal operating temperature. With the carburetor automatic choke off the fast idle cam, adjust the engine idle speed by using a tachometer. Then make the throttle rod adjustment.

  1. Install each linkage. Loosen its bolts so that the rods B and C can slide properly.
  2.  
  3. Lightly push the rod A or the transmission throttle lever and the rod C toward the idle stopper and set the rods to idle position. In this case the carburetor automatic choke must be fully released. Tighten the bolt securely to connect the rods B and C.
  4.  
  5. Make sure that when the carburetor throttle valve is wide-open, the transmission throttle lever smoothly moves from idle to wide-open position (operating angle: 45-54°) and that there exists some room in the lever stroke.
