2009 387 Peterbilt Motor mounts / ISX 871

[yetison]

Feel a bit stupid to ask this, but another driver tried convincing me that to change my motor mounts on my truck, I need to remove my transmission... Then he told me I could put the mounts in either way, and they would be just fine..

So, remove tranny ???? Seems like the bracket on the frame rail could be removed if jacking the motor wouldn't clear enoug to put in top part..

And which way do these mounts go in ??
thought the larger mount goes between engine bracket, and frame bracket...
