Good day. So I finally took a longer than usual highway run this weekend. All went well, great oil pressure, temps, except that I detected an overall vibration when going above 55mph. It was not felt at the steering wheels or coming from the tires, but more like engine or tranny. Once I let go of the accelerator, it would stop. I would also feel it if I was on the downside of an over path. I know this might be a hard one to comment on, but any suggestions of where to begin to look at would greatly be appreciated. Thanks
Do this, engine running in park, bring the rpm up slooowly to maybe 2000 rpm, see if it still vibrates, if not you can rule out engine and it’s accessories.
