Default Help ASAP!!!!

I had a shop change my rear end fluid recently. They added High Performance Valvoline 80w-90 GL-5 LS gear oil. It says it's specially formulated for limited slip, high horse/torque power applications. The mechanic said with this fluid I did not need the GM limited slip additive. I don't know how true this is, should i add it myself or will i be ok? I have the same Auburn High Perf Diff That was installed in the Firehawk and SS cars. Any suggetions?

If you are getting clutch chatter then add the additive. If it's quiet after it is warmed up then just leave it alone.

What does clutch chatter sound like? Should i listen at a particular rpm range/speed, at idle, certain gear?

Probably most noticeable at low speed when making a turn.
