I posted this to another thread, but I managed to do it by myself last weekend.
It cured the problem completely. Now the car runs very smooth even with full throttle. I know it will come back at some point, but I am not scared anymore as I can fix it. It takes time to drain out, but the procedure is very simple.
(I know I shouldn't do this way but) I even didn't have to use axle stands, just used a pump jack as I really didn't have to go under the car, just my arm. Two 4L bottle of Honda Genuine CVT fluids are not cheap, but well-worth, I belive.
Also, in Japan, many people started using this additive for extra protection. I saw so many reviews (20-30 people at least) - actually cured the problem by just adding 200-300ml of this SOD-1 to CVT fluid tank even without flushing the old oil.http://sod1plus.com/
Has anyone tried this in UK?
