Check transmission Fluid with vehicle running and on a flat surface. (make sure engine is warmed up before you check. Transmission dipstick handle is usually colored "red". Engine oil is usually yellow (Must be checked with engine off if engine was running prior let engine sit in off position for at-least 2 minutes). Good Luck contact me if you need more help.

SOURCE: "1991 Chevy Cheyenne 4X4 K1500

The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

TESTING

  1. Remove the ECT sensor from the vehicle.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the engine coolant sensor temperature vs. resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not met specification shown in the temperature versus resistance chart, it must be replaced.
  7. The sensor may also be checked in the vehicle. Unplug the sensor and attach a digital ohmmeter to the two terminals of the sensor.
  8. Using a calibrated thermometer, compare the resistance of the sensor to the ambient air temperature.
  9. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  10. If the sensor does not met specification shown in the temperature versus resistance chart, it must be replaced.

1991 Chevy K1500 4wd transmission stuck


More than likely the trans is not stuck in neutral, it could possibly be low on fluid. That is the first thing I would check. If it is full then try putting the transfer case into 4X4 high and then low and see if it will move. If it does after you do this, then the problem would be inside of the transfer case. If it does not move in any gear it would more than likely be a internal failure of the trans.

Not shifting properly


it sounds like the screen at the bottom of the transmission is stopped up not allowing the trans fluid pressure to build up to change gears. Just drop the the trans fluid pan and see what you got under there if its dirty clean it with parts cleaner and see what you got, if its dirty thats more than likely the culprit if its not it could be be the torque converter, but its best to try the small easy stuff first.

Transfer case chevy truck


a np241 from a th400/4l80e would have the 32 spline that is need for a manual trans, one from a 700r4/4l60e is 27 spline input, in 94 the switch was changed and the cam to activate the switch was changed so if you get a 94 np241 you then will need to wire in a 94 switch into the older harness
