Good Day,

I have a 2012 Honda Civic LX auto, whenever my car shifts from second to third (I can hear it bc I have a muffler), it vibrates/jerks like something is grinding. Anyone else have the same issue or know how to fix it?

Thank you

 

Check ATF, motor mounts.

 

I just changed my ATF last year, but I will check out my motor mounts. Thank you!
