Vibration and engine shift ?

noahinbr said:

I'm new to the group, just bought a used 2008 versa with 18,000 miles. Love it.

We're getting a vibration from just under the hood, only when the brake is pressed down, and you switch from Park to Drive or Reverse. Not getting it at all with the hood up. Anyone else get a vibration like that?

Also, is it normal for the engine to shift a bit when you switch from Park to Drive/Reverse?

I've included a video of it here: Versa Engine Shift - YouTube


Thanks for any suggestions.

I am no expert... the vibration when brake is pressed and you switch form park to drive or reverse...... might be that the rubber bumpers between the hood near the front need adjustment and are letting the hood vibrate. reduce the clearence and make the hood touch the rubber bumpers.

I believe what you are seeing with the motor shifting position is thetop rubber motor mounts moving. Check to see if they are cracked.

keep us posted

Might need to accept that as the "nature of the beast". I've heard a low frequency vibration in most automatics when in a drive gear with foot on brake, engine idle is supposed to decrease when you shift into a drive gear and don't apply any throttle. The manufacturer does it's best to isolate drivetrain from driver input with all the rubber they use to do that, but when you have brakes applied to the driven wheels, any vibration from the drivetrain is going to get transmitted through the axles, into the brakes and up to your foot.

Also motor rocking is normal, the engine is supposed to move when load is being applied, too much indicates the rubber motor/tranny mounts are worn out, but this looks about right. The engine and tranny are supposed to "float" relative to the chassis, but within a given limit, too much movement is bad, but there is a certain amount of give that the rubber motor mounts are supposed to have.
