Ok today i took out my old auto tranny mount, and swapped in the 6-speed 1LE tranny mount. First thing i noticed was it was a little smaller in height. Now i seemed to picked up some vibration, becuase it seemed to lower my tranny about a 1inch. Now is this normal, and gotta wait for it to break in or what????I dont want my tranny get messed up....

This is a common problem. But I would feel good about what you noticed. Most people don't pick up on that 1/2 drop in heighth.
So yes that difference causes your driveshaft angle to be off a little bit. After noticing that vibration in my own car, I removed it and haven't re-installed it yet.
However a few members have installed it and say that after about 2-3 days that vibration will go away, and no negative side affects will be caused. I believe someone has had theirs in for over 4 years now.

What I am going to do, when I stop being lazy is ask Energy Suspensions or Prothane for several of those stack plates (one comes with your kit) I think if you had about 5 of them and some long bolts, it all should like up. No vibration, and really strong mounting.
They'll probably mail you them for free?<b>15.41</b> @ 89.80 & 15.45 @ <b>91.64</b>, 2.21 60ft, 3,440 raceweight, using <b>OEM</b> Equipment. <br />\'98 L67/M49 w/ 134,000 miles before spun bearing. \"<i>It\'s all stock, Baby</i>!\"Comment

some people just stack a bunch of washers up to restore stock height.
i personally used an energy suspension mount and haven't looked back; i couldn't perceive any difference in shifter height though the vibration was awful for a little while.Comment
