14-06-2025Good 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.

> 3 dayI 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.
