1996 chev k1500 whining drivetrain

1996 chev k1500 cheyenne 5.7L manual trans: a whining sound from drivetrain that matches vehicle speed; no different when in or out of gear, or when turning, or foot off gas pedal. Higher pitch when faster, and ''wobbles'' almost like a warped brake rotor. Those probably bad too but not this. Just recently replaced the whole rear axle/diff unit and new clutch last year. U jts assumed OK. Would a bad transfer case bearing (?) make this noise? I have also noticed recently the shifting to be ''touchy'' as in less than optimum ''syncro-mesh'' i.e., gears grind easier if I am not more careful, as if (and i have no idea if this works) the gearbox (?) lost a bolt and is off center or something. I assume the two could be related.

SOURCE: whirring/whining noise from rear trans-axle

check your rear end and make sure it has plenty of gear oil..if full then there is friction in it somewhere and it is probly getting ready to go out.

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.

Need your trans rebuilt from the sounds of it! After time, the clutch discs inside wear out(Just like the clutch of a manual vehicle), and will start slipping.

Sounds like bearing in the front of my 1500 chev in four wheel only lound whine


If it whines when in the 4x4 position but not at any other time then the noise you hear may be coming from the transfer case and is caused by the high gear load of driving both axles on a this type of surface. If you are driving in the 4x4 position on any dry hard surface you will hear some noise from the transfer case and usually it is a noticeable whine. Also, driving in 4x4 on a dry/hard surfaces greatly adds to the strain and wear on the power train. It would also be a good idea to have the both axles and transfer case fluid levels checked to be sure none of them are low. Hope this helps a bit and good luck!

1996 chev k1500-- when the weather turned cold the transmission seems to slip at start up in the morning. After I get going it seems to shift and run fine. Maybe feels a little soft on the shift for...


it sounds like the trans filter needs changed. the fluid will be thicker when its cold and will not pass through the clogged filter as easy. As you drive it the fluid heats up and becomes thinner then is able to pass through easier.

My 1993 K1500 will not shift from 2 to drive or overdrive. Manual shift from 1-2 works, Also speedo quit at the same time.


its the speed sensor located on the drivers rear side of the transfer case, it has a 2 wire plug, the sensor screws into the tcase and is really easy to replace and fairly cheap at any parts if you buy the new one first it will help you find it by matching it up its a common problem with this vehicle, when it goes out the speedo quits and the computer doesn't know your moving so it doesn't shift the trans properly

What gear is in the 92 chevy cheyenne 4.3 5 speed


What is the gear ratio for your vehicle? I'm not sure if that is what you mean, but there should be a metal tag under one of the bolts at the pumpkin on the axle that should tell the gearing ratio for that vehicle. Hope this helped.
