Welcome to the MCF family.
Slick 50. Never used the stuff.
I've discussed transmission fluids with lots of tech's. No one has ever recommended anything other than Dextron III or the newer Dextron IV.
L.S Differentials are a different story. Most recommend synthetics with an additive there.
As for engine lubricants, most everyone I know recommends full synthetics, and not just additives. Most feel that Royal Purple is about the best out there (of course, a topic of big discussion in itself). Personally, between my wife and myself, we have about 650,000 mi on full synthetics, and we've never so much as pulled a valve cover, nor do we have any leakers.
I'd save the $$$ spent on additives and just put the good stuff in your crankcase. Here is the list of GM4718M GM registered and approved lubricants. I try to stick to this list, especially if your car is supposed to run on full synthetics, like so many of today's cars are.
