Just bought a 2000 v6 with a blown trans... Put a new trans in... Runs and drives and shifts good.. When I am going straight no noise, when I am in a parking lot or making a semi hard turn I get a constant squealing noise. I figured it could be in the rearend because as soon as I turn it makes the noise. 1 wheel spins faster than the other when turning. The guy I bought it from told me the gears were replaced and he thought a posi unit was put in.. He didn't know what brand.. Could have been a factory unit. I dont know. Anybody have a similar issue.
