when?? in how many KM??

 

look in your owners manual. I think it's like 30k miles. My car is at 32k and I've changed my tranny and diff oil 3 times.

 

I changed mine with Redline ~ 3,000 Miles. the redline make a noticeable difference in the shifting smoothness...plus I wanted to change it early to maybe remove any tiny metal particles that could have been trapped in the transmission from manufacturing.

 

I changed to Royal Purple at 8k miles (trany and diff) and change ever 10-12k miles or Once a year.

 

See Sig. It does smooth out shifting.

 

ha, I was just thinking about this topic earlier in the day.

KY: got the specs on that Royal Purple? (what kind you put in each...)

I know I could search but it comes up with a Bagillion different threads...

thanks!

 

I was looking for my tranny fluid place on my car and i couldnt find it ! im gonna look in the manual tomorrow

 

I just have the Royal Purple Max Gear Syn fluid in the trany and diff. I bought 4 qts and have about .75 qt left over.

the trany took almost 2qt I think and the diff took just over 1qt. So far 2100 miles on the fluid and better than ever.
