2017-2019 Nissan Sentra 1.6L FWD – Remanufactured Automatic Trans

Description

Engineered for turbocharged front-wheel sport sedans, Nissan Sentra 2017-2019 Remanufactured Transmission units handle 1.6L MR16DDT turbo engine output in FWD compact chassis. This remanufactured CVT automatic transaxle manages 188 continuous horsepower, 177 lb-ft maximum torque, and an engine ceiling of 6500 RPM while maintaining secondary pulley clamping hydraulic line pressure of 850 PSI.

A compact die-cast aluminum transaxle case encases micro-polished variator pulleys and an auxiliary 2-speed sub-planetary gear unit linked by a high-strength steel drive belt. The hydraulic pump housing receives a hardened steel flow control valve with an anodized sleeve to prevent bore wear and pressure drop. Sump volume holds 7.5 quarts of Nissan NS-3 CVT fluid. Total dry transaxle weight measures 165 lbs, fitted with a balanced lockup torque converter.

Key Features of Nissan Sentra

Fleet operators choose to buy Nissan Sentra 2017-2019 remanufactured transmission units to restore fast boost response and eliminate drive belt shudder in turbocharged compact sedans. Comprehensive factory reconditioning replaces all wear components and recalibrates the auxiliary gear module to guarantee continuous torque transfer under spirited driving conditions.

• Auxiliary 2-speed sub-planetary gear unit expands ratio spread while keeping casing dimensions ultra-compact.
• High-tensile steel push belt eliminates slip during rapid boost onset and turbo spooling.
• 7.5-quart fluid capacity stabilizes transaxle operating temperatures under continuous spirited driving cycles.
• 2017-2019 Sentra replacement valve body eliminates ratio hunting across intermediate acceleration steps.
• Sentra 2017-2019 torque converter package features reinforced clutch linings to stop low-speed shudder.
• Stepless ratio spread delivers broad mechanical advantage from 4.007:1 launch down to 0.550:1 overdrive.
• 850 PSI secondary clamping pressure locks pulley sheaves fast to protect the steel drive belt.

Turbocharged Compact Pulley Thermal Dynamics

An internal variable displacement pump maintains hydraulic clamping pressures between 150 and 850 PSI, keeping fluid sump temperatures within 165°F to 195°F. Input torque absorption handles 177 lb-ft at 2000 RPM without belt slippage. The dual-range sub-planetary pulley spread maintains the 1.6L turbo engine in its optimal torque band. An external transaxle cooler loop sheds excess heat through dedicated fluid lines, protecting pulley sheave surfaces and internal needle bearings from micro-pitting under sustained boost.

Front-Wheel Drive CV Axle Interface

Dual 25-spline differential output hubs link straight with factory front constant velocity axle shafts. Internal differential side gear backlash is held within 0.0025 inches on dial indicators, stopping front-wheel driveline vibration. Bell housing dowel sleeves align the transaxle case square against the engine block face, preserving input shaft centerlines under hard acceleration.

Dynamometer Spin Testing Maintenance Schedule

Every transaxle undergoes computerized dynamometer spin testing under simulated road load resistance to calibrate stepper motor travel, verify secondary clamping pressures, and evaluate forward clutch hold. This CVT transaxle is not engineered for nitrous-assisted street racing, aftermarket turbocharger additions, or operations using non-approved universal automatic transmission fluid without proper CVT ratings.

• Check transmission fluid level and deterioration counter data using scan tools every 30 operating days.
• Drain and refill approved Nissan NS-3 CVT synthetic fluid every 30,000 miles.
• Flush external transmission fluid cooler circuits every 12 months to prevent particulate blockage.

Transaxle Crate Manifest Warranty Inclusions

A 3-Year unlimited mileage warranty protects commercial fleet buyers against premature mechanical and hydraulic defects. Each sturdy wooden transport crate holds the complete remanufactured automatic transaxle, a balanced lockup torque converter, installation paperwork, cooler flushing guidelines, and fluid specification documentation tags specifying approved CVT fluid.
