2005 Cadillac CTS • 6 cylinder 2WD Automatic • 60,000 miles

I have a 2005 cadillac CTS, not high performance, shifts great but there is a wining noise coming from the transmission. It is higher pitch at lower rpm, what can I do to fix this.

Disconnect the fan belt andstart the car. Run for a few minutes and if the noise stops it is coming from the engine. Otherwise take it to a trans shop and get an opinion from him. If it's engine noise eitherfrom a p/s pump bearing like idler pulley or alternator.
