> 3 dayFit perfect on my 2005 GMC sierra 3500 duramax with the Allison 1000 transmission. Took a while to get it lined up. Dont listen to the idiots on the internet though, the preload plate is required to be installed as well as the mount. Energy suspension notes that in the installation manual as well. Its not specifically listed for the Duramax/Allison application but this is the right mount.

Greater than one weekBought this mount in January. Has been on for a month now. Notice that it is firmer. Easy to install. Comes with new hardware. Have a trans jack or floor jack and a piece of thick wood to cover the trans pan. Undo the bolts and lift the trans just enough to get the old one out. Install the new one. Lower the trans enough to start the bolts. Drop the trans and tighten the bolts. I bought Merchant Automotive engine mounts. When I install them. I will review those also.
