A transmission is a drivetrain component in a rear-wheel-drive vehicle that features internal gears which enable the vehicle to travel at different speeds on the road when the engine is turning at the same rpm. Nissan Quest transmission can either be a manual transmission which require the shifting of gears as needed, or an automatic one which upshifts and downshifts without driver input, according to prescribed parameters, although most can be shifted manually to a point. Transmission depends upon the year model and trim of your Nissan Quest.

 

Most cars started with manual transmissions and later on use an automatic one with overdrive or vice versa. The Nissan quest started with 4-speed automatic overdrive, then an additional of an optional 5-speed manual transmission with overdrive for the following year, then back to automatic only until 2004 when the 5-speed automatic transmission came back.
