Hey all.
I just changed out to Royal Purple Diff and Trans fluids. 5speed 2005 GT with 21000KM on the meter.

My main reason was longevity and the benefits of synthetic really.
I had heard about performance gains etc etc but never really put much stock into these claims.
However, now with the purple in the diff and trans I can say the shifts are butter smooth and the car seems to run a little more freely and happily through the gears.

the biggest thing though is the shifts. Wow, That I can feel right away.

Have you used their motor oil yet? Thinking of going with it at my next oil change

Treatz

Not yet no.. I have a good 5000k left on the previous SYN oil change, but i will most definately be switching to ROYAL motor oil

I am a cynic and a skeptic but you are the third source that has switched to Royal Purple synth in a Tremec tranny and noticed a palpable difference.. Crap....now I may have to try it myself.

what type did you use?

I always used Redline in my other toys....race and owner proven....hell, the owner of the company goes 15k between oil changes alone...

think it would make a difference in the auto?

Treatz

I don't see it hurting..
if I can feel a difference in the smoothness of gear selection and when engaged i'm sure the auto's would benefit to
