CVT Nissan CVT NS-3 - one of the most common continuously variable transmissions in the line of the Japanese brand, installed on models from Juke to X-Trail. However, if repairs or replacement are necessary, owners are faced with a problem: original spare parts are expensive, and the market is full of offers marked “analog”. How not to make a mistake with your choice and not run into a fake? In this article we will analyze all compatible CVTs, their technical features and selection criteria.

It is important to understand that even complete analogues by catalog number may differ in the firmware of the control unit if they are intended for different markets (Europe, Japan, USA). We analyzed the manufacturer's data, reviews from service station technicians and technical documentation to create an up-to-date list of replacements, taking these nuances into account. If you are looking for an option for a specific model, use the cross-number table below.

1. Original numbers of the NS-3 variator and their interpretation

Corporation JATCO (subsidiary Nissan) produces CVTs NS-3 under several articles. The main differences lie in gear ratios, belt material and mechatronics firmware. Here are the basic numbers that can be found in catalogs:

  • 🔧 31726-3M50D - version for Nissan Juke (1.6 l, 2010–2014) with gear ratio 6.394
  • 🔧 31726-3M51A - modification for Nissan Qashqai J10 (2.0 l, 2007–2013), features a reinforced oil pump
  • 🔧 31726-3M52A - option for Renault Koleos (2.5 l, 2008–2016) with a modified switching algorithm
  • 🔧 31726-3M50E — “European” version for Nissan X-Trail T31 (2.0 diesel, 2007–2013)

The first three digits (317) denote a family of variators, 26 — transmission type (front-wheel drive), and the letter at the end (D/A/E) — design revision. For example, CVTs with index E have an updated oil cooling system, which is critical for engines with high torque.

💡

Before buying an analogue, check the markings on the body of the old variator - the exact article number is indicated there, and not the general family number.

2. Complete analogues from JATCO: what can be installed without modifications

Manufacturer JATCO supplies CVTs NS-3 not only for Nissan, but also for other alliance brands Renault-Nissan-Mitsubishi. This means that some models have 100% compatibility on fastenings, connectors and firmware. Here are proven analogues:

Original number Nissan Analogue from JATCO Applicability Features
31726-3M50D JF016E Nissan Juke, Renault Captur (until 2015) Requires firmware adaptation for engine HR16DE
31726-3M51A JF015E Nissan Qashqai J10, Suzuki SX4 (2.0 l) Reinforced drive shaft, compatible with MR20DE
31726-3M52A JF017E Renault Koleos, Nissan X-Trail T32 (2.5 l) Additional oil cooling radiator

Important: CVTs with index E at the end (for example, JF016E) are electronically controlled, whereas older versions (JF015) - hydraulic. Replacing hydraulics with electronics is impossible without flashing the engine ECU.

3. Budget analogues: what the aftermarket offers

On the spare parts market you can find CVTs from third-party manufacturers, positioned as “complete analogues”. However, their quality varies from "acceptable" to "disastrous". We tested several brands and highlighted those that no complaints from the masters:

  • 💰 ATP (article ZF31726-3M50D) is a Taiwanese manufacturer that offers CVTs with a 1-year warranty. Minus: noisier operation when cold.
  • 💰 Delo (article TCV31726) is a Korean company specializing in CVT. Plus: comes with an updated belt NS-3.
  • 💰 Febest (article W0133-1631097) is a Japanese brand, but assembled in China. Difference: reinforced input shaft bearings.

⚠️ Attention: Cheap analogues (price below 80,000 ₽) are often equipped with low-quality belts, which “burn out” after 30–50 thousand km. Check for certificate availability ISO/TS 16949 from the seller - this is the minimum sign of quality.

If your budget is limited, consider purchasing contract variator from Japan. The cost of such a unit is from 50,000 ₽, but it is important to check:

Mileage (optimally up to 80,000 km)|

Condition of the oil (there should be no metal shavings)|

Integrity of mechatronics connectors|

Availability of original tag with number-->

4. Compatible with other CVT models

Sometimes owners try to install CVTs from other families, for example, NS-2 or RE0F10A. This extremely risky, since they differ:

  • 🔄 Gear ratios (y NS-2 range 2.349–0.394, y NS-3 — 2.631–0.378)
  • 🔌 Connectors for connecting to the ECU
  • 🛢️ Oil type (for NS-3 required NS-3 Fluid, for NS-2 — NS-2 Fluid)

The only acceptable option is replacement NS-3 on NS-3F (modification for hybrids). But this requires:

  1. ECU firmware for a new control algorithm.
  2. Replacing the oil pump (in NS-3F it is highly productive).
  3. Installation of an additional cooling radiator.
What happens if you pour NS-2 oil into NS-3?

Oil NS-2 Fluid has lower viscosity at high temperatures, which leads to belt slippage and accelerated wear of the cones. After 10–15 thousand km, vibration will appear during acceleration, and after 30 thousand km, a major overhaul of the variator will be required.

5. How to check the compatibility of an analogue before purchasing

To avoid errors, follow this algorithm:

  1. Check the car's VIN with base Nissan Consult or ETIMS — the exact article number of the variator for your configuration is indicated there.
  2. Check the number on the case old variator (for example, JF016E-4E00A). Last characters (4E00A) indicate a revision - it must match the original and the analogue.
  3. Specify engine type. CVTs for gasoline and diesel engines have different torque converter locking algorithms.

⚠️ Attention: If you buy a variator from disassembly, be sure to check it at the stand. Even an apparently serviceable unit may have worn cones or mechatronics. The cost of diagnostics (about 3,000 ₽) will be recouped by avoiding repairs.

💡

Never buy a CVT if the seller cannot provide a photo of the tag with the serial number. Counterfeits are often sold without labeling.

6. Frequent mistakes when choosing an analogue

In practice, even experienced car owners make mistakes. Here are the most common:

  • 🚫 Ignoring firmware. For example, a variator from Renault Captur physically approaches Nissan Juke, but without adaptation the ECU will be “stupid” when switching.
  • 🚫 Saving on oil. Replacement NS-3 Fluid to universal CVT Fluid leads to scuffing on the cones after 20 thousand km.
  • 🚫 Incorrect tightening torque. The bolts securing the variator to the engine must be tightened firmly 45–55 Nm, otherwise vibration will occur.

Another typical problem is purchasing a CVT from a “donor” of a different configuration. For example, a variator from Nissan Qashqai 2.0 4WD not suitable for version 1.6 2WD, since it differs in the gear ratio of the main pair.

7. Where to buy: trusted suppliers

To minimize risks, order CVTs from official distributors or trusted sellers:

Supplier Specialization Pros Cons
Official Nissan dealers Original spare parts 2 year warranty, VIN check Expensive (from 150,000 ₽)
EXIST.ru Original and analogues Fast delivery, authentication check Prices are 10–15% higher than the market
JP Car Parts Contract CVTs from Japan Low prices (from 50,000 ₽), check at the stand Long delivery (3–4 weeks)

When purchasing from private sellers (for example, Avito or Drom) require:

  • 📄 Photo of the variator passport (tag with number).
  • 🎥 Video of work on the stand (without jerks or extraneous noise).
  • 🔧 Warranty of at least 6 months (for contract units).

FAQ: Answers to frequently asked questions

Is it possible to install a CVT from a Nissan Juke on a Qashqai?

Technically yes, but only if they match:

  • Engine capacity (eg HR16DE or MR20DE).
  • Drive type (2WD or 4WD).
  • Year of manufacture (before 2013 or after 2014, as the firmware has changed).

Otherwise, you will need to reflash the ECU, which will cost 15–20 thousand rubles.

How is the NS-3 different from the NS-3F?

NS-3F - modification for hybrid vehicles (for example, Nissan Note e-Power). Differences:

  • Reinforced belt (resource up to 200 thousand km).
  • Additional electric oil pump.
  • Changed algorithm for working with an electric motor.

Install NS-3F instead of NS-3 It is possible, but the cooling system will need to be modified.

What kind of oil should I put into NS-3 analogues?

Manufacturers of analogues (for example, ATP or Delo) universal oils are often recommended, but for maximum resource use:

  • Nissan CVT Fluid NS-3 (original, article KLE52-00004).
  • Ravenol CVT NS-3 Fluid (German equivalent, approved Nissan).

An oil change is required every 60 thousand km (or once every 3 years).

How much does it cost to replace an NS-3 CVT?

The cost depends on the type of work:

  • Replacement with a new original: 150,000–200,000 ₽ (spare part + labor).
  • Installation of contract: 70 000–120 000 ₽.
  • Repair current: 40,000–80,000 ₽ (depending on the wear of the cones and mechatronics).

You can save money if you buy a variator yourself and pay only for the work (from 15,000 ₽).

How to check a variator before buying?

Minimum checklist:

  1. Rotate the input shaft by hand - there should be no play or jamming.
  2. Check the oil on the sump magnet - large chips indicate wear on the cones.
  3. Connect to a diagnostic scanner (for example, Launch X431) and check mechatronics errors.

If the seller refuses to diagnose, this is a reason to doubt the quality.
