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, Chris
