The 4 qts of Dex III in the trans.

It use to be with these Tremec 6 speeds that if you put synthetic Dex III in there they shifted smoother. I've put Amsoil Dex III in a few Vettes with real good results. This Camaro seems a bit different though, when I put the Amsoil in this trans, 3rd became a bit notchier going into 3rd when cold.

I'll probably switch back to regular Texaco Dex III that came OEM, or maybe try Mobil 1 or Royal Purple that I have heard works good. They seem to have a lighter cold viscosity which may be what the synchros like better when cold.

When I changed mine I did notice that the factory fill seem really thin coming out compared to the Amsoil I put in there. I thought that was going to be a good thing, but 3rd doesn't like it when cold.
