eCVT drin&fill or complete flush??
 

My car is going to reach 60,000 service pretty soon. Most my schedule services has been completed expect the eCVT transmission service. Although I got the Metric W fluids already, I still have questions. I want to understand how to do it before is too late.

1. I got 12 bottles of Metric W, so should I use only 6 of them for drains&fills? Or 12 bottles of them for complete flush?

2.How to do it? I need step by step processes lists.

3.After I finished it, how long should I do it again? some people claim is every 60,000miles, but some people told me 30.000miles afterword.

PS: Gosh. In Southern California most dealer service want to charge me $450 to $500. Does that make any sense to you guys? :confused:

On the Prius (which has a power split device of similar design), AFAIK, you don't need to flush it. There's no torque converter.

I can't speak to the amount needed.

$450-500 sounds way too high. I got my 06 Prius' "transmission" fluid changed for $109.16 per http://priuschat.com/threads/changin...2#post-1287381. Toyota has one use their ATF WS.
