OK, here it is but remember it is a lot easier to tell you this over the phone than it is to write it down, at least for me.
First you must go to an auto glass replacement company and buy 1 tube of auto glass replacement urethane and 1 bottle of pinchweld primer that is made by the same company that made the urethane. Note: NOTHING else but auto glass replacement urethane will work, if you try silicone or anything else you are wasting my time for writing this and your time for trying it.
Next remove the shifter handle from the shifter and clamp it in a vise or anything that will hold it steady. Now take the pinch weld primer and prime the metal of the shifter handle where the handle makes contact with the shifter, and on the opposite side where the head of the bolts contact the handle. Let the primer dry for 15 minutes.
Next take the urethane and apply it the the areas that you primed. You want to form a coating of urethane 1/8" on both flat sides of the handle (the side that touches the shifter and the side that the bolt heads clamp down on). Try to make the coating of urethane as flat and as smooth as you can. Do not fill in the bolt holes or you won't be able to bolt the handle back on to the shifter. Now, you must let that urethane dry completely, it will take about 2 days. YES, I MEAN 2 DAYS! If cut corners or don't let it dry correctly and it still makes noise you have no one to blame but yourself.
While the urethane is drying go to the hardware store and buy 2 flat washers that are about 1" to 1.25" inches in diameter. The washers must have the correct size hole to fit the bolt snuggly. You will notice that when you put the washers on the bolts and align them up with the handle that the bolts over lap, and one will ride up on top of the other. You MUST grind the washers so that they don't ride on top of each other. You want them to butt up against each other without riding on top of each other. Now that everything is completely dry bolt the handle back onto the shifter, Tighten the bolts down REAL tight, and go back and retorque them after one days use. If you don't make the bolts tight enough the handle might move around. When I say real tight, I mean as tight as you can without stripping the threads.
If you did everything like I said the shifter will make NO noise anymore.

I know this will make the shifter STFU! It sure as hell did on mine.
