Just have the gearoil changed to the above and I have one comment:
Altought it is pretty expensive stuff, it's worth every penny! I would never believe that just oil can make such a great difference! My gearbox was always pretty smooth and quiet but now it's unbeliveble smooth, quiet and works almost like CVT! You almost can't tell when the gears are changed.
I didn't want to belive in all opinions on this forum regarding the ATF but now I have to take it all back.
Thanks for advises and use Amsoil ATF!!!
