Got a Buick Century or Allure (that's the Canadian name for the LaCrosse) with an automatic transmission that's thumping or clunking on gear shifts?

A worn transmission mount is a common culprit.
This is a brand new replacement mount, part number 2818.

It's also known by interchange numbers A2818, 22146688, and 10419764.

The brand is 4M, it's made in China, and it comes with a 2-year manufacturer warranty.
The mount has a fresh 'new' finish.

It's a relatively simple part that plays a big role – it holds the transmission in place and absorbs the torque from gear changes.
When it's worn out, you'll feel and hear more vibration and harshness, especially when shifting from Park to Drive or under acceleration.

Replacing it can restore that smooth, quiet Buick ride.
It's a straightforward job for a DIYer with some basic tools and a jack.

Make sure your model matches before ordering.

A small part for a big improvement in driving comfort.
