I was wondering about adding some low friction additives too my manual trany and my diff on my 2003 Z06 vette. any advice on this subject?

Low friction additives? I wouldn't...if the fluid gets too slippery, the synchros in the transmission won't work so well.

 

Mr. Moly. Great stuff do the research.

I use it in my transmission, and I also used it in my Z28 which it had 92,000 miles on when I bought it. It is really slick! They don't recommend it in new engines, because it may keep the rings from seating.
