Vibration at 1100 rpm
I replaced the tranny mount in my 96 LS400 recently. But I still get the vibration at 1100 rpm while driving.
I did the following tests today.
1, I parked the car and the gear is in “Park” and revolved the engine to 1100 rpm, no vibration.
2. I parked the car and the gear is in “N”, engine at 1100 rpm, no vibration.
3. The car was parked and no moving by pressing the brake pedal, the gear is in “D” or in “3”, revolved the engine to 1100 rpm, and the vibration was reproduced.
I am thinking the vibration is caused by bad engine mounts. What else could cause the problem?
Thanks

All you can do is replace all the mounts, and 90% of the time those will be the source of all your vibration problems. If replacing the mounts doesn't solve the problem, there is something more serious that needs to be looked at.
Also, is your vibration at any speed inparticular or does it occur at 1100rpm nomatter what speed your at. Do you notice any other vibrations that appear at other speeds (highway)?
