Hi Everyone,
I recently bought a Jazz 1.4 CVT from 2005 with 37000km(sorry 23000miles) and I also have a Civic Hybrid 2010 with CVT as well.
The Jazz had the judder and I flushed the gearbox with Honda CVT fluid.
First I drained the old fluid and refill with new. I did a test drive and the judder fell almost to 30% let's say.
Then I performed the ''stall test'', D+brake+2500revs for 10 sec etc..etc. From that moment judder was gone completely!
Went back home drained the CVT fluid again, and refill with new one.
