Transmission Fluid - ZR-1 Net Registry Forums

9T1 Red ZR1 · 10-04-2017

I know this has been brought up before, but regarding transmission fluid, what is now recommended? I tried to buy Castrol TWS 10w-60 from ebay but they sent Castrol Supercar 10w-60. They said TWS is out of stock nationwide. I have the Fidanza with a little gear rattle so I want to change the fluid. Any products that can still be bought that are acceptable?

Thanks,
Bill

I used Amsoil Manual Synchromesh Transmission Fluid 5W-30 on my last change....It works very well.
