Hi all, I'm new here and I have a few concerns. I've searched for answers before posting and I can't find anything close to what I'm experiencing.
My issue comes when I'm driving and just cruising and the speed is constant. It sounds like the engine is getting ready to rev but it's just constant with speed. The noise goes away as soon as I lift my foot offnthe gas pedal. Which leads me to think it might something the acceleration.. but idk.. need your guys help and opinions.
I wonder if it's the torque converter unlocking if the car thinks it may need to downshift soon. That would allow the engine to gain a few RPM's, maybe enough to hear, but not enough to move the tach. This is just speculation on my part, as I don't know a whole lot about modern automatic transmissions.
