What noise does a bad pinion bearing make?
A bad pinion bearing makes a whirring noise at all speed levels, during acceleration or deceleration. Instead of rumbling, a bad pinion bearing whirs due to its turning speed, which is a lot faster than the carrier, depending on the gear ratio.
Can a torque converter make a whining noise?
The torque converter is built with a clutch mechanism; when the mechanism fails, you’ll notice a whining or rattling noise that might not be heard when the car is in the park. If the whining noise increases when you engage the transmission gears, it tells you to have torque converter problems.
