My car has a rear from a 2000 trans am. It has 3.73's and the limited slip or whatever. I am changing the fluid and installing a TA cover. What fluid do I need? Do I need any additives or anything since it's limited slip?

 

some 90 wt gear fluid with a bottle of GM limited slip additive.

You must use the additive with the limited slip.

 

I used Mobil 1, 75w-90 with gm additive.

 

I used Wolfs Head oil with Kendall additive, and have had no problems.

 

lucas oil with gm addative.

 

I agree, the Lucas oil & GM additive works the best for the money.
