- Remove the transmission pan as previously outlined.
- Loosen the locknut.
- While pulling the servo lever toward the outside, insert a 6mm feeler gauge between the adjusting screw and the servo piston pin.
- Under the conditions of Step 3, tighten the servo adjusting screw to 10 inch lbs.
That's inch lbs., not ft. lbs.! Use an inch lbs. torque wrench, or don't attempt this adjustment.
- Install the locknut and remove the feeler gauge.
- Install the transmission pan.
The kickdown band adjusting screw is located on the left-side of the transmission case.
- Loosen the locknut and back off approximately 5 turns. Test the adjustment screw for free turning in the transmission case.
- On models through 1980: Use an inch pound torque wrench and tighten the adjusting screw to 72 inch pounds. On 1981 and later; tighten the adjusting screw to 69 inch pounds. (The torque specifications shown are true torque with no adapter on the wrench).
- On models through 1980; back off the adjusting screw 3 full turns. On 1981 and later models; back off the adjusting screw 3 1 / 2 turns.
- Hold the adjusting screw to prevent turning and secure the locknut to 30-41 foot pounds.
LOW AND REVERSE BAND
- Raise and safely support the front of the car. Drain the transmission fluid and remove the oil pan.
- The allen socket headed adjusting screw is located at the servo end of the strut. On models through 1980; loosen and remove the locknut from the adjusting screw. Tighten the adjusting screw to 41 inch pounds of true torque (no adapter on wrench). Back off adjusting screw 7 1 / 2 turns. On 1981 and later models; Loosen and remove the locknut from the adjusting screw. Tighten the adjusting screw to 43 inch pounds of true torque. Back off the adjusting screw 7 turns.
- Install the locknut on the adjusting screw. Hold the adjusting screw in position and tighten the locknut to 25-35 ft. lbs.
- Install the oil pan using a new gasket. Fill the transmission with the proper amount of transmission fluid.
This adjustment is performed externally at the adjustment screw on the right-side of the transmission.
- Loosen the locknut.
- Tighten the adjusting screw to 10 ft. lbs. (ft. lbs. not in. lbs.).
- Back the screw of 3 / 4 of a turn and tighten the locknut.
- Run the engine at an idle until it reaches the normal operating temperature.
- 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.
- The gap between the stop and the adjusting screw should be between 0.05-0.10mm.
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.
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.
The shifter end of the linkage rod is slotted. With the lever and transmission both in Neutral, loosen the locknut and adjust the linkage for smooth operation. Grease the sliding parts of the linkage and tighten the nut to 10 ft. lbs.JM600
- Apply chassis lube to all sliding parts.
- Place the selector in the NEUTRAL position.
- Turn the adjusting cam until the distance between the adjusting cam and the selector lever end is 15-16mm.
- Install the switch with the slit mark aligned with the (N) position.
- If the switch is not properly connected, loosen the attaching screws and adjust its position by moving it forward or backward.
- 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.
- Adjust the connection range of the switch so that in any position, the lever can be moved an equal distance in either direction.
- The inhibitor (Neutral) switch is located at the base of the shift control under the console cover.
- Loosen the set screw that retains the shift lever handle to the shift lever. Remove the handle.
- 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.
- 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.
- 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.
- 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.
- Place the selector lever in NEUTRAL.
- Raise and support the car on jackstands.
- Remove the lower screw on the neutral start switch.
- Loosen the switch attaching bolts.
- Insert a pin, (2mm in diameter) into the lower screw hole in the switch. Move the switch until the pin drops into a hole in the rotor behind the switch.
- Hold the switch in that position and tighten the attaching bolts to 5 ft. lbs.
- Using an ohmmeter, check the switch across the leads for continuity.
DOWNSHIFT SOLENOID INSPECTION
- Raise and support the car on jackstands.
- Uncouple the connectors on the wiring at the solenoid.
Transmission fluid will drain from the hole after the solenoid is removed. Have a drain pan ready to catch it.
- Remove the solenoid and O-ring.
- Connect a 12V source across the solenoid wires to verify that the plunger is operational. If not, replace it.
- Apply a coating of clean transmission fluid to the O-ring and install the solenoid. Fill the transmission.
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.
- Install each linkage. Loosen its bolts so that the rods B and C can slide properly.
- 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.
- 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.
