2005 Lesabre vibe after mount change

10-17-2013, 08:28 PM
On my 2005 Lesabre, I just replaced the front transmission mount (the one behind the radiator). Drove it immediately after I changed it and now I have a vibration anytime I do any kind of rpm increase. Letting off the accelerator it reduces greatly. The mount I took off was definitely bad. Did I do something wrong? Is there a trick to installing it? Or maybe I possibly have another mount problem, and replacing this one, magnified the other ones. I sure could use some suggestions. Any

Not the same, but on my 2005 GMC 2500HD I replaced the transmission mount with one I bought off of Amazon and had the worst vibration you could imagine. The mount was made in China and my thinking is the rubber was too hard and didn't allow it to absorb the vibrations and transmitted it directly to the frame.

Just a thought...
