Nissan then switched from toroidal to pulley-primarily based CVTs in 2003.[43] The Edition on the CVT utilised Along with the VQ35DE motor inside the fourth-generation Nissan Altima is claimed to be effective at transmitting increased torque masses than other belt CVTs.[44]
Both equally of those Gains are why CVT gearboxes are commonly used in hybrid cars. The smoothness of the CVT pairs effectively Along with the smoothness of an electric motor, although The 2 combine for outstanding gasoline economic system.
Action: This sort of sounds typically involves instant consideration from a professional mechanic. Driving using a clunking transmission could potentially cause additional hurt and most likely bring on an entire transmission failure.
