      on the driver's side of the shifter toward the front there should be a small cable. correct adjustment allows the switch to which it connects know the car is in park so the key can be turned to the locked position. it's kind of a pain to adjust.

      if you are going through bearinggs and seals lie this then something bigger is the problem. it could be that that where the bearing sits is too loose, or that the axle shaft is slightly bent and causing the problem. is this the rear or the front you are having a problem with? I assumed you are talking about rear but want to make sure

      Sorry saw again on title it says rear. so the axle shaft could be problem. was this truck ever in an accident that affected the rear, or did it ever hit something hard to that side?

      Something is wrong with the axle shaft surface that makes contact with the bearing rollers (this is likely). Sometimes the axles are too pock marked at that position and are worn and cause the bearings to fail. It has a cause, it is not the bearing being a defect, Chinese or not. I'll assume that the differential housing has been filled with gear oil to the proper level through the fill plug.

      Did you check the condition of the fluid, maybe it needs to be replaced? Do you have check engine light? Do you smell something burning in your transmission?

    The trans works good, but has a high pitch squeal that changes with rpm increase
    The squeal starts after the trans is warm and is in all drive ranges even neutral and park.

      Are you sure it's the transmission and not the belts or pulleys? Sounds like a loose slipping belt or a worn bearing on one of the pulleys to me.

    I have recently noticed a growl which seems to come from rear end or rear wheel bearings
    Truck has 138000 miles. Noise intensifies with speed and has no relation to gear changes. Noise only appears when moving, no unusual sound when stopped.

      sounds like you have the right idea, it could be the bearings, if you are noticing a growling from the rear tire area, take off the rear drums make sure it isn't the rear brake shoes, it could be if they haven't been replaced in a long time. and I hope it is cause a growling bearing can lead to extra damage if not taken care of. Don't keep letting it go check it out sooner than later

    When put in gear the car barley moves whats wrong with my clutch
    im buying the car from a friend and i asked him what was wrong with the car and all he said was it was the clutch and that right now it will barley move

      Did you hear any noise coming from transmission or clutch possibly? Possible clutch is not engaging or there an internal damage; transmission shift linkage is at fault. Did you check the condition of oil maybe low?

    Installed a rebuilt transmission, gears will change but will not engage. what could be wrong
      10/20/2010 MOONSTER_TOOLZ
      Could be the fuse to PCM controller is blown or the PCM itself is at fault. Consider also a faulty speed sensor. Have your engine scanned with a scan tool to retrieve the codes then post it here so that the community will able to help you in diagnosing the trouble of your vehicle.

    Transmission will not down shift
    it will shift up. but when i deaccelerate it stays in the high gear until it eventualy dies out its an 04 transmission in a 97 z71in ideas what the problem might be?
      10/20/2010 MOONSTER_TOOLZ
      You may have a faulty shift solenoid or the throttle position sensor is failing. Check your transmission fluid maybe low also.

    Engine bogs down when going over 30mph.
    replaced intake manifold and valve cover gaskets. dexcool anitfreeze got into cat. convertor. could that be the problem or could it be something else?
      10/20/2010 MOONSTER_TOOLZ
      Could be your throttle position sensor is failing. Do you have a check engine light? Even though, there's none I recommend to have your engine scanned for stored trouble codes to detect the exact fault of your engine.

      It was the catalytic convertor clogged

    At start up in the mornings my baretta takes a few shifts before it will go into gear, Fluid is fine, clean, no leaks, ?

      It could be. The Vacuum Modulator monitors engine vacuum by a rubber vacuum hose which is connected to the engine. Engine vacuum reacts very accurately to engine load with high vacuum produced when the engine is under light load and diminishing down to zero vacuum when the engine is under a heavy load. The modulator is attached to the outside of the transmission case and has a shaft which passes through the case and attaches to the throttle valve in the valve body. When an engine is under a light load or no load, high vacuum acts on the modulator which moves the throttle valve in one direction to allow the transmission to shift early and soft. As the engine load increases, vacuum is diminished which moves the valve in the other direction causing the transmission to shift later and more firmly. Consider also the throttle cable that monitors the position of the gas pedal through a cable that runs from the gas pedal to the throttle valve in the valve body; It may be needs adjustment.
