Q: My engine/transmission has a rough/growling when in gear and at acceleration.

asked by on May 12, 2017

My car has a rough/growling vibration when in gear and at acceleration. It lasts a few seconds as I put tranny in reverse/drive from a stop and as I step on the gas pedal to get up to speed. I replaced the u-joints, rebuilt the rear diff bearings and seals, new tranny mount, new engine mounts, new plugs and coil, and lastly a new harmonic balancer. So far nothing has solved the issue. It's not a suspension/steering issue as far as I can tell. All steering components seem to be okay (no loose ball joints, no oil leaks in cv joints, etc).

My car has 111500 miles.
My car has an automatic transmission.
