I can't tell you about the Royal Purple ATF, but I've been using Mobil 1 Synthetic for some time now and it is definetely an improvement in smoothness. Also, Mobil 1 was just recently approved by GM as a replacement to the factory fill.

Royal Purple
I had Royal Purple Synchromax, put in my Transmission, Friday. The first time, I got in the car, and shifted from 1 to 2 , and can tell it was smoother, and easier to put into first gear. Well only time will tell, if it get better, after it been in there a while, but I notice an improvement already.

I just wanted to ask, if anyone has had any trouble with ROYAL PURPLE SYNCHROMAX if they put that in there Z06 Transmission. Thanks.

Tom,
The best thing to do his check with your dealership, that you got the warranty from, and ask them if changing the fluid to Royal Purple will void the warranty. I have had the fluid in for about a month, it is better, than what was in there stock.

Even though my baby only has 8,100 miles on it, the bullet is just over four years old. The dealer just put RP Synchromax in my Z06.
If it doesn't work out well, I'll let you know.

Yeah, thanks for the feedback. Last night I did extensive research on Royal Purple Synchromax on the web. The company seems to be very open about their products that might cause warranty problems and their Synchromax was not mentioned as being a problem for manual transmission warranty issues. So from what I am able to find we are good to go with this product in our Corvette's. I ordered 4 qts. this morning from the link at the beginning of this thread, http://www.rpmoil.com/shop/welcome.html , and look forward to the improvements in shifting Royal Purple is supposed to give. Thanks again for your comments.

There is suspicion that it could do damage. I say stay with a sure bet.

my #1 gripe about royal purple is that they use a PAO base without a good seal modifier. that means years later you're a LOT more likely to develop leaks than with...say...amsoil that also uses a PAO base but has a great additive pack.
my personal choice is redline which is an ester base. incredible cold flow, requires nil for viscosity modifiers and has a softening/swelling effect on seals just due to the nature of being a group 5 ester. that's golden for an older car. also has the best shear stability of any of the major oils to the best of my knowledge
redline d4 atf does meet gm spec and works wonderful in late c5s

the insanely good cold flow numbers are obvious when you go to drive on a 40deg day. shifting is good from the start and is perfect within a few minutes. with the OE oil shifting was a bit clunky when cold

Boy this is an old thread. Since that time I've switched to using RP Synchromax. Even better!
