Energy Suspension 3.1129G Large 7.5 CC Transmission Mount for GM

Had a nasty driveline vibration on my 2006 Chevy 2500 Duramax. Turns out my stock mount was in 2 pieces! Good fix and upgrade!

I installed this on my 2002 Chevy Silverado 2500HD Duramax/Allison pickup and it works great. Truck feels like it shifts better after replacing my stock rubber one with this poly mount.

Better then OEM and last longer

Holding up as expected

Its a Tranny mount. I used same product line on the engine mounts. I have a vibration from nor changing this mount. These are superior to oem rubber mounts.

Great product, just as described.

Good product for my 700R4. Had no instructions to show what the extra bracket was supposed to be used for. Make sure you also use poly engine mounts if you are going to use this.

Installed on my 2005 gmc 3500 Dually 4x4 with Allison 1000 transmission. Took me 20 min to install. Very good quality. Took care of my shake on accelerating.

Bought 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.

Fits great, used it to replace my extremely worn out mount on my nv4500 swapped 1986 k30
