Hey there,
These vehicles are NOTORIOUS for bad A/C clutch bearings, alternator bearings and water pump bearing noises. It could be any of the 3, and you might want to get a long long long handle screw driver or some other long piece of metal you can use as a stethoscope to place on all three of the parts to see which is loudest. To prove it is not a transmission problem, remove the belt and start the engine. If no noise is present with the belt removed, you don’t have a transmission problem.
Once the belt is removed spin each pulley as someone listens to the component with your stethoscope to locate the noise.
Blessings,
Austin Davis
