I took it to a guy that specializes in transmissions and he informed me my Vue has like a thousand little teeth in it that would be outside of area.
The CVT gearbox, and versions thereof, has been around info lebih lanjut Because the dawn in the motorcar, but it was the introduction from the Variomatic gearbox by Dutch car or truck maker DAF in the 1950s that observed CVT come to be more commonplace in autos.
