Upon start-up on my Malibu, 350 Vortec & TH400, there is a whining sound. It will increase with rpm and sometimes decrease when the car is put in drive. I’ve taken the alternator and power steering belts completely off and the whining noise is still present. After the car is driven a while the noise will stop but it often returns just as easily.
The TH400 was gone through this summer by a reputable shop. The engine was rebuilt at the same time by me.
Any suggestions will be appreciated.
