Hi first time poster here

I have a 1997 Magna TF wagon auto and i'm getting a bad vibration when i select Reverse or Drive but it goes away when in Park or Neutral, i replaced all the engine mounts but still get the vibration any ideas? thanks.

Need more info. Does it do it while your driving or just at idle when stopped. Just for a few seconds? How's your idle?

Thanks for the reply, it only vibrates at idle when in gear and it idles at 1000rpm. I increased the idle and made it a bit better but turned it back down because i didn't want to ruin the gearbox when it slams into gear from high rpm.

Hows the fluid level? Are your gear changes smooth and has there been a change in gearbox operation since the vibration started?

Changed the oil a few days ago due the oil being overfull in the box and yes the gear changes is smooth, vibration is still the same.

If your gearbox works fine otherwise I would rule that out. My tf sedan has a creeping idle. Creeps between 500-750 and has a vibration. The vibration gets fast and slow depending on revs. Nothing that I would consider bad but rough idle seems to be a common thing with magnas. You can feel it in the car. As with yours when it's in park or neutral is not there. My car runs fine otherwise. I don't tend to worry about it.

Before you upped the idle was yours doing the same?

Vibration stayed the same when reving and doesn't get harsher or smoother after starting the car, only goes away when in park, reverse or driving before coming to a stop at a set of lights.
