Has anyone used rp in their vantage yet?

 

the details for all the fluids are right there in the manual.

I went liquid moly. stayed with the factory specified weight though.

 

My dealer tells me that for '06-early '08, Aston is recommending changing to a lighter oil for the Transmission to make cold-shifting easier. Some owners have had trouble shifting, and if so there are replacement bushings for the shifting arms to correct this problem.

 

An update to my earlier post. My mechanic tells me that the bushing problem and thick transmission oil was only an issue with about 1000 vehicles in '06MY. All follow-on vehicles have the new bushigs and a lighter oil. The reason I am following this closely is that I had a major clutch failure on my '08MY, where the clutch came apart at about 9,000 miles. Here's my mechanics comment to me: "the clutch has been upgraded to stop the locating pins from parting causing this problem".

 

Symptoms were the clutch would not fully release so it was hard to shift gears. The worst indication was 1st gear, where on hard acelleration the clutch would not release at all until the engine and RPMs got back around 4,000, then I could force it out of gear. Also, in other gears especailly 3rd and 4th I often heard a slight grinding sound before the transmission would go into gear. The clutch was not fully releasing.
