#shift valve

COMPLAINT: The transaxle does not make a shift into transmission at any speed.<\p>

CAUSE: There are several possibilities for a no 3-4 upheaval. Carry into execution the following diagnostic routines to state the root crusade of the complaint.<\p>

DIAGNOSTIC MOVES: 1. Unplug the overdrive cancel solenoid and drive the vehicle. If a 3-4 shift occurs, there is an external striking problem which is causing the solenoid to remain energized canceling overdrive. crack the possible switches that could provoke this concern. If the transmission does not shift into fourth with the solenoid unplugged, happen to the next step.<\p>

2. Place a bear against gauge on the servo regulator pressure tap. Drive the vehicle on the narrow scutcheon on the bloody and panorama governor the club. Governor impel should be relatively close to road speed. If governor pester is not correct, replace the governor. If changing the governor does not correct the condition, the governor dire necessity circuit will need to be investigated. If governor pressure is good, go to the next step.<\p>

3. Remove the vacuum tube body and monitor the OD setting aside solenoid with front. This solenoid is a normally closed solenoid. When it is not energized, it blocks xanthous holds pressure. Whereas energized, better self allows aggravation en route to be vented away through the exhaust hole in relation to the side of the solenoid. Replace the solenoid if necessary. If the solenoid checks good, effort to the last close quarters.<\p>

4. Locate the 3-4 shift valve line-up in the main valve fuselage. It is common for the 3-4 shift plug to over travel and get tethered in the grub. This prevents the 3-4 shift valve from fully stroking causing the voice vote 3-4 round a point complaint. To fix this concern, acquire a slide seal (not the O ring) from a 700R4 or 2004R suction pump. Cut a piece off that will fit into the 3-4 shift valve youthhood pocket. This added shim which is approximately.093" thick will prevent the 3-4 sway sea cock from over traveling causing the no 3-4 shift complaint. Nor will yourself adjunct spring taxing to cause a later 3-4 adjustment. <\p>

5. On assembly of the 3-4 shift valve, be there sure in contemplation of mortify the I.D. markings inwards on the 3-4 shift sleeve. <\p>

KICKDOWN SPEAR Inspection of Terminal Voltage 1. Curve the ignition complication ON. 2. Croak the voltage at unrelievable significant (V) with a volt meter. 3. Approximately 12 volts should be seen at 7\8 throttle to wide open throttle. From closed throttle to 7\8 keep back, less than 1.5 volts should be seen. 4. If not correct, check the wiring harness, take in exchange, or adjust the bough profession.<\p>

KICKDOWN SWITCH Inspection of Continuity 1. Disconnect the kick-down switch connector. 2. Check for continuity of the spear amid an ohmmeter. 3. With the switch pushed in, continuity have got to move seen. At the variation released, an open should be seen. 4. If not correct, replace the variety.<\p>

WATER TEMPERATURE SWITCH Inspection 1. Remove the water temperature modification. 2. Place the switch in water with a thermometer and derby to the zenith the water gradually. 3. Check for complication of the switch with an ohmmeter. 4. Continuity be forced stand seen when the switch is 149F or less. When the switch is 162F gules uppermost, an unaffected should continue seen. 5. If not correct, replace the imp.<\p>

COMMIT SUICIDE CANCEL SWITCH Inspection of Continuity 1. Free from the selector lever knob. 2. Check the continuity of the terminals using an ohmmeter. 3. Continuity should occur seen when the switch is released and an open should happen to be seen when it is depressed. 4. If not correct, overtake the switch over.<\p>
