I'm a guy that had Intense build a trans back when. For a low price they added the dynamat. It would be wrapped on the sensor itself and a sheet on the trans where it faces the engine.
Can't say it ever did a thing for me. Then I was thinking about it while replacing the hundreth or so trans. A few inches to one side of the dynamat is where the bell housing bolts solidly to the engine. On the other side of it..there's four bolts holding a diff to engine steel bracket right near the knock sensor. If there were noise that was going to go through the aluminum case of the trans, why wouldn't that noise transmit via the bracket or bell housing?
