The B17 Nissan Sylphy 1.8 (with MR18/MRA8 1.8L engine) is equipped with Nissan’s Xtronic CVT (Continuously Variable Transmission), a torque-converterbased automated gearbox optimized for smoothness and fuel efficiency.

Key Features of the Xtronic CVT in the Sylphy B17:

• Type: Continuously Variable Transmission (CVT) with torque converter
• Design Goals: Lighter construction, reduced internal friction compared to previous CVT versions  
• Performance Feel: Delivers responsive acceleration; reviewers note it ''feels livelier than the numbers suggest'' and is ''more than willing to rev up upon pressing the throttle'' still with silky smooth, gearless shifts  
• Durability & maintenance caution:
  ''You need to betulbetul jaga is her CVT… never skimp out on its maintenance… always do oil change early'' 
  This echoes common advice: maintain CVT fluid regularly to avoid potential issues.

Transmission Specs & Operation:

• Drive Layout: Front-engine, front-wheel drive
• Gear Ratios: Unlike stepped-shift automatics, the CVT adjusts seamlessly across a continuous ratio spectrum for optimal power delivery and efficiency  
• Fluid Type: Uses Nissan’s NS2 (original spec); NS3 sometimes recommended, but NS2 is optimal according to community advice
