    Hi all,

    Plymouth Voyager 89, 2.5 Turbo, 3 speeds

    Since a couple of week I have a sharp noise and a small vibration when
    the car run higher than 60 Km/h.
    In the last days the noise becomes to be more and more accentuated.
    Initially I supposed the noise is coming from the bearings.
    I changed both bearings, but the noise persists. I changed also the
    axels one year ago, don't think the noise is from axels.
    If I run at more than 60 Km/h and put in Neutral, the noise is still
    there even than the RPM come to 8-900 (idle), until the speed is less
    than 55-60 Km/h. If I stop the car, put in Neutral and I accelerate
    up to 3-4000 RMP, there is not this noise.
    Someone told me the noise is coming from automatic transmission.
    I changed the fluid myself each year (ATF3+ for Chrysler ) and
    adjusted bands (at correct values with a dynamometer wrench torque) ,
    the fluid is not smell as burn and the level is OK.

    Any ideas, please.
    Thank you,
