Nissan GT-R R35: secrets of all-wheel drive ATTESA E-TS - design, problems and repairs

Nissan GT-R R35 is a legendary Japanese supercar that has been surprising the world with its technical solutions since 2007. One of the key elements that ensures its phenomenal dynamics and handling is the all-wheel drive system. ATTESA E-TS (Advanced Total Traction Engineering System for All-Terrain with Electronic Torque Split). This technology, inherited from racing prototypes Skyline GT-R, turns R35 into a real “monster” on any road - from city streets to track turns.

However, like any complex engineering system, all-wheel drive GT-R requires careful attention. Many owners are faced with questions: how exactly is torque distributed between the axles? What signs indicate a problem? Can the system be modified to improve performance? In this material we will analyze the device in detail ATTESA E-TS, typical problems, diagnostic methods and give practical recommendations for maintenance.

How the ATTESA E-TS all-wheel drive system works in the Nissan GT-R R35

System ATTESA E-TS in Nissan GT-R R35 is an electronically controlled clutch that dynamically distributes torque between the front and rear axles. Unlike traditional "all-wheel drive" systems, where the drive to the front axle is engaged only when slipping, ATTESA works constantly, sending from 0% to 50% of torque to the front axle depending on conditions.

Main components of the system:

• 🔧 Electromagnetic clutch — located in the transfer case and controlled by the unit ATTESA ECU.
• 📊 Sensors — wheel speed, steering angle, longitudinal/lateral acceleration, throttle position.
• 🖥️ Control unit — analyzes data from sensors and calculates the optimal torque distribution (up to 1000 times per second!).
• ⚙️ Differentials - rear interwheel with electronic locking, front open (in basic versions).

In normal mode (for example, when driving uniformly along the highway) up to 98% of the moment is transmitted to the rear axle, which makes GT-R essentially a rear-wheel drive car. However, when accelerating aggressively, turning or sliding, the system instantly redirects up to 50% torque to the front axle, preventing drifts or drifts. This algorithm does R35 incredibly stable at high speeds.

All-wheel drive operating modes: when and how to use them

Nissan GT-R R35 offers several modes of operation of the all-wheel drive system, which can be selected depending on road conditions. Incorrect mode selection not only affects handling, but can also lead to premature component wear. ATTESA.

Mode	Torque distribution	When to use	Limitations
Normal (ATTESA Auto)	0–50% on the front axle	Driving in the city, highway, dry asphalt	Maximum efficiency, but not for extreme conditions
Snow Mode	Up to 30% on the front axle, early connection	Snow, ice, wet asphalt	Limits engine power to ~300 hp.
R-Mode (Track)	Aggressive distribution, up to 50% when slipping	Track racing, sport driving	High clutch wear due to frequent starts
VDC Off (Drift)	Minimal intervention, predominantly rear-wheel drive	Controlled drift, for experienced drivers	Risk of damage to differentials!

It is important to understand that the mode Snow Mode not intended for continuous use - it reduces engine performance and can lead to overheating of the clutch ATTESA when driving for a long time. But R-Mode, on the contrary, is optimized for the track, but requires mandatory “rest” of the system after intense loads (recommended 10–15 minutes cooling after 3–4 laps).

⚠️ Attention: Using the mode VDC Off on public roads is fraught not only with fines, but also instant wear of the rear differential with uncontrolled drift. In racing versions GT-R (For example, Nismo) reinforced differentials are installed, but even they require regular checks after track days.

Typical GT-R R35 all-wheel drive malfunctions and their symptoms

Despite the reliability, the system ATTESA E-TS not eternal. The most vulnerable elements are the electromagnetic clutch, sensors and control unit. Here are the key signs that indicate problems:

• 🚨 Jerks during acceleration - especially at speeds of 40–80 km/h, when the system tries to redistribute the torque.
• 🔥 Transfer case overheating — burning smell, increased body temperature (normal: up to 90°C).
• ⚠️ Errors on the dashboard - codes C1105 (clutch malfunction), C1109 (problems with the speed sensor).
• 🔄 Unstable torque distribution — the car “stumbles” when cornering or suddenly slips.
• 💰 Liquid leak - oil stains under the transfer case (liquid Nissan Matic-S).

One of the most common problems is wear of clutch friction discs. On average they withstand 80–100 thousand km when driving quietly, but on the track the resource is reduced to 20–30 thousand km. Another common problem is oxidation of sensor contacts, especially after pressure washing or driving through deep puddles.

What happens if you ignore jerks during acceleration?

If you ignore the jerks caused by the wear of the ATTESA clutch, the friction discs will begin to “dust” - metal shavings will fall into the fluid, which will lead to jamming of the clutch. Repair in this case will cost 150–200 thousand rubles (replacement of the coupling + flushing of the system).

Another critical point - fluid in transfer case. Many owners forget that it needs to be changed every 60 thousand km (or once every 2 years). Using unsuitable liquid (for example, regular ATF instead of Nissan Matic-S) leads to increased wear of the coupling and failure of solenoids.

All-wheel drive diagnostics: from scanner to visual inspection

If you notice symptoms of a malfunction, the first thing you need to do is diagnose it. Let's start with the simplest thing - reading errors. For GT-R R35 scanners that support the protocol are suitable CAN-BUS, for example:

• 🔌 Launch X431 Pro - reads codes ATTESA And VDC.
• 📱 Carista (with OBD adapter) - a budget option for basic errors.
• 💻 Consult-III Plus — professional scanner for dealership centers.

After reading the errors, go to visual inspection:

Check the fluid level in the transfer case (should be between MIN and MAX)

Inspect the sensor wires for oxidation or breaks.

Listen to the transfer case for extraneous noise (humming, grinding)

Make sure there are no oil leaks from the drive shaft seals

Take a test drive with R-Mode turned on (there should be no jerking) -->

For in-depth diagnostics it may be necessary checking clutch resistance. Normal values for ATTESA E-TS in GT-R R35:

• Coupling winding resistance: 3.2–4.8 Ohm (at 20°C).
• Temperature sensor resistance: 2.2–2.7 kOhm (at 20°C).

⚠️ Attention: If the scanner shows an error C1130 (clutch solenoid malfunction), don't try to reset it without repairing it! This can cause the clutch to lock in one position (eg 50/50), making the vehicle uncontrollable at high speeds.

Maintenance and repair: what you can do yourself and what you can’t

Some system maintenance operations ATTESA E-TS You can do it yourself, but most repairs require specialized equipment and experience. Here's what the average owner can do:

Self service:

• 🔧 Changing the fluid in the transfer case - required Nissan Matic-S (volume: 1.8 l).
• 🧹 Cleaning sensor contacts - use CRC contact cleaner.
• 🔍 Checking the differential oil level (front and rear).

Works for professionals:

• 🛠️ Replacing clutch friction discs - Requires disassembly of the transfer case.
• 🔌 Diagnostics of the ATTESA control unit - You need an oscilloscope and software.
• 🔄 ECU firmware — when updating or tuning the system.

If you decide to replace the fluid yourself, follow this algorithm:

1. Warm up the car to operating temperature (5-10 km drive).
2. Raise the car on a lift or ramp.
3. Remove the crankcase guard and locate the drain plug on the transfer case.
4. Drain the old fluid (~1.6 l should come out).
5. Pour new fluid through the filler hole (use a funnel with a long hose).
6. Bleed the system: start the engine, switch modes ATTESA (Normal → Snow → R-Mode) with a delay of 5 seconds each.

Cost of professional repair ATTESA E-TS in Russia (2026):

• Replacing the coupling: 120–180 thousand rubles (with work).
• Control unit repair: 30–50 thousand rubles.
• Replacing drive shaft seals: 15–25 thousand rubles.

All-wheel drive tuning: is it worth modifying the ATTESA E-TS?

Many owners Nissan GT-R R35 are thinking about tuning the all-wheel drive system to improve dynamics or adapt to the track. However, there are some nuances here. Firstly, ATTESA E-TS originally designed for power up to 600–650 hp — when the engine is forced above this threshold, the clutch begins to slip, and the clutches wear out 2-3 times faster.

Popular modifications:

• 🔥 ATTESA reinforced coupling - for example, from Nismo or Cusco (withstands up to 800 hp).
• ⚡ ECU firmware — change in torque distribution algorithms (for example, earlier connection of the front axle).
• 🔄 Front differential lock - for better cornering (but worsens handling on ice).

However, before tuning it is worth considering:

• ❌ Warranty for the vehicle will be cancelled.
• ⚠️ Component life will be reduced (even with reinforced parts).
• 💰 Cost quality tuning starts from 300 thousand rubles.

Comparison with competitors: why ATTESA is better (or worse) than other systems

System ATTESA E-TS often compared to all-wheel drive competitors such as Audi Quattro, BMW xDrive or Porsche PTM. Let's look at the key differences:

Characteristics	Nissan ATTESA E-TS (GT-R R35)	Audi Quattro (RS models)	BMW xDrive (M5/M8)
System type	Electronic clutch, permanent rear-wheel drive	Torsen center differential, symmetrical drive	Multi-disc clutch, adaptive distribution
Max. front axle moment	50%	60% (in dynamics)	100% (short term)

Reliability	High, but sensitive to overheating	Very high, minimal wear	Medium, complex electronics
Tuning potential	Limited (up to 800 hp)	High (up to 1000+ hp)	Medium (up to 700 hp)

Advantages of ATTESA E-TS:

• ✅ Simplicity of design - less electronics than in xDrive.
• ✅ Predictability — clear torque distribution 0–50%.
• ✅ Lightness — the system weighs 15–20 kg less than Quattro.

Disadvantages:

• ❌ Limited power — without modifications cannot withstand over 650 hp.
• ❌ Sensitivity to overheating — requires cooling after the track.
• ❌ Difficulty of repair — there are few specialists in Russia.

Overall, ATTESA E-TS is a compromise between reliability and performance. It's perfect for GT-R R35 as for an everyday supercar, but inferior Quattro in racing conditions and xDrive in adaptability.

FAQ: answers to frequently asked questions about all-wheel drive Nissan GT-R R35

Is it possible to disable all-wheel drive on the GT-R R35?

No, turn it off completely ATTESA E-TS You can’t - the system is always active. However, in mode VDC Off The torque distribution is shifted to the rear axle (up to 98%), which simulates rear-wheel drive. Complete disengagement requires physical removal of the clutch, which is not recommended due to the risk of damage to the transmission.

What kind of fluid is poured into the transfer case of the GT-R R35?

The manufacturer recommends using Nissan Matic-S (item: KE909-99932). Alternatives: Mobil ATF 3309 or Idemitsu ATF Type-J, but only in the absence of the original. Do not fill with Dexron or other universal ATF!

How much does it cost to replace an ATTESA coupling?

The cost depends on the type of coupling:

• Original (Nissan): 80–120 thousand rubles (part) + 30–50 thousand rubles (work).
• Reinforced (Nismo/Cusco): 150–250 thousand rubles (set) + 50 thousand rubles (labor).

Replacement time: 2–3 days (disassembly of the transfer case is required).

Is it possible to drive with error code C1105 (clutch malfunction)?

Short term - yes, but not recommended. Error C1105 indicates problems with the electromagnetic clutch, which can lead to:

• Unpredictable torque distribution (e.g. 50/50 permanent drive).
• Overheating and jamming of the clutch.
• Damage to the control unit ATTESA.

If an error appears, check the fluid level and sensor contacts. If the problem persists, contact service.

How to check the functionality of ATTESA without a scanner?

Simple test:

1. Start the car and turn on the mode R-Mode.
2. Drive away quickly (on dry asphalt).
3. If the system is working properly, you will feel smooth acceleration without slipping (the front axle is connected immediately).
4. If it slips or feels jerking, there is a problem with the clutch or sensors.

Also note VDC indicator on the dashboard - if it flashes during normal acceleration, this is a sign of a malfunction.
