This is simple!!! I had the same problem in my GS. The part is called the supercharger coupling. It is made of nylon and can't be bought from the dealer BUT can be found in Ebay for about $30. This is a NEW part for the Eaton M90 supercharger. That is all it is!! The holes in the coupling wear slightly oblong creating a little bit of slop and it sounds TERRIBLE.

Be careful with the sealing surfaces behind the supercharger snout, reseal with a gasket maker (Loctite makes some) and refill with the correct fluid.

How do i fix the transmission in my 2000 buick regal gs supercharged

What is the problem you are having? Transmissions are complex, especially automatics. So if you are asking this question then, I would recommend taking it to a trusted ASE certified mechanic.

I have a 99 regal 3.8 supercharged car starts then dies. it loosing power to the fuel pump. have replaced fuel pump and ignition switch because i thought there was a prob with security system.i am realy...

It does sound like you have a passkey (security) issue. If the BCM does not recognize the key cylinder code the BCM will send a comand to the PCM to shut down the fuel system.
When you say you replace the "ignition switch", was it the switch or the tumbler.
If the tumbler was replaced you will have to relearn the key code.
Let me know if the key tumbler was replaced and I will tell you how to relearn the key code.

Can you take off the supercharger from a 1998 buick regal and replace it with a metal plate so its not used. Will the car run without the supercharger?

The supercharger is how air gets into the engine.
Two rotors force the air into the cylinder heads creating more pressure thus more horsepower.

Your engine is designed to run with the parts that are on it. If you change the intake manifold to one on a 3800 without a supercharger you will get into a situation where you will have to change the injectors and add other parts to make it run correctly. Not to mention the reprogramming issue.

If the supercharger is the problem try these people.

I bought a s/c from them and it works better than the original.

99 buick regal won't start

Hello, the Regal seems to have that problem. Insert your key in the ignition and turn it but do not turn the car on, make sure you here the fuel pump kick in, then at the end of you r fuel rail there should be a cap, remove it, use a very thin screw driver and push that part in, Be careful it's going to squirt gas, that's a good sign. If it does not, check your fuel filter. And last, if nothing above described works first check your negative wire on your fuel pump, second your injectors, they might be clogged.
Best of luck, God Bless.

1998 Pontiac Grand Prix GTP Supercharger coupler

The rattle you are/were hearing is typical on the Eaton blowers. After they get some miles on them, the coupler wears out and the holes become ob-longed or out of round which causes the rattle you are hearing.
Usually at idle you can hear it very clearly.
I have changed a few, and they are pretty simple to change. Just take off the supercharger belt, then you may have to remove your alternator bracket, depends on which years, drain the supercharger oil with a spray bottle sprayer (it does stink badly) then just remove the 10 or so bolts that hold the snout to the housing. Remember to keep track of where they go, some are different lengths.
You may have to use a rubber mallet, or your hand to hit the snout around to break the gaskets loose. Pull off the old black hockey puck looking thing (coupler) clean out the snout, attach new coupler, then reassemble and put new supercharger oil back in, and your rattle will be gone, at least for another 100k miles.
Best place to get a coupler is at,
Costs about 30, plus the few bottles of oil for the supercharger.

Buick Regal Gs supercharger nose assembly please help if you can

the 3.8" supercharger (belt) pulley? You need a special tool as they are press fit. and

both carry it and offer the tool for rent as well.

Much of the noise comes from the coupler, however there are case (needle) bearings as well that wear, Those are much more difficult to replace.
