Automatic transmission <em>Nissan Murano</em>: device, malfunctions and secrets of long service

Nissan Murano is one of the most popular crossovers in the Japanese brand’s lineup, combining comfort, dynamics and reliability. However, even such proven models have weaknesses, and automatic transmission often becomes a source of headaches for owners. In this article we will look at all generations Murano (Z50, Z51, Z52), types of automatic transmissions that were installed on them, typical faults and methods for eliminating them - from prevention to major repairs.

Feature Murano is that in different markets and in different years it was equipped with different transmissions: from classic torque converter RE0F10A/RE0F10D to modern CVTs JF017E. We will analyze each in detail, tell you how to recognize the first symptoms of problems, and provide a checklist for diagnosis. And we’ll also reveal unique nuance with the oil pump in the automatic transmission Murano Z51which is often missed even by experienced craftsmen.

Types of automatic transmission in Nissan Murano by generation

Over 20 years of production Murano went through three generations, and each used different transmissions. Let's look at them in detail:

• 🔹 Z50 (2003–2007) — classic 4-speed automatic transmission RE4F04B (for engines VQ35DE 3.5 l) or CVT JF010E (in some markets). The first is known for its reliability, but is sensitive to the quality of the oil.
• 🔹 Z51 (2009–2014) — 5-speed RE5R05A (for VQ35DE) or variator JF011E (for QR25DE 2.5 l). This is where the problems started oil pump and solenoids.
• 🔹 Z52 (2015–2026) — variator JF017E (for VQ35DD 3.5 l) or JF016E (for hybrid versions). Modern but high maintenance.

It is important to understand that even within the same generation, transmissions could differ depending on the market. For example, Murano for the USA often came with RE5R05A, and for Europe - with a CVT. You can check the type of automatic transmission by the VIN code or by the plate on the box itself (usually visible when the hood is open).

Weaknesses of automatic transmission Nissan Murano: what breaks most often

Despite the reputation of reliable cars, Murano has several common transmission problems. They can be divided into three categories:

1. Mechanical wear — clutches, bearings, bushings. This is especially true for cars with mileage over 150,000 km.
2. Electronics and solenoids - a common problem RE5R05A and variators. Manifested by jerking or delayed switching.
3. Oil pump — unique "disease" Murano Z51 with RE5R05A: the pump wears out and does not create the required pressure, which leads to gear slippage.

Let's take a closer look:

Automatic transmission type	Typical fault	Symptoms	Repair cost (approx.)
RE4F04B	Worn clutches 3-4 gears	Shocks when switching, burning smell from oil	from 40,000 ₽ (replacement of clutch package)
RE5R05A	Oil pump malfunction	Loss of traction, error P0730 (wrong gear ratio)	from 60,000 ₽ (pump replacement + flushing)
JF011E/JF017E	CVT belt wear	Vibration at speeds of 60–80 km/h, “kicks” during acceleration	from 80,000 ₽ (replacement of belt + cones)

⚠️ Attention: If your Murano Z51 with RE5R05A It started to feel “stupid” when accelerating, but there are no errors - don’t rush to change the solenoids. First check the oil pressure in the box! Low pressure (less than 4 bar at idle) almost always indicates pump wear, not electronics.

Automatic transmission diagnostics: how to recognize the problem at an early stage

Many owners Murano They ignore the first signs of an automatic transmission malfunction, attributing them to “behavioral features.” This leads to expensive repairs. We have compiled a checklist of symptoms that cannot be ignored:

Jerks or delays when changing gears (especially from 1 to 2)

Extraneous noises (hum, grinding) when coasting

The Check Engine light comes on with errors P0700–P0799

Oil leakage from under the pan or oil seals

Vibration at speeds of 40–60 km/h (typical for CVTs) -->

If you notice any of these symptoms, the first thing to check is:

1. Level and condition of the oil in the automatic transmission (should be red, without the smell of burning and metal shavings).
2. Presence of errors through the diagnostic scanner (even if the "Check Engine" is off).
3. Oil pressure in the box (for RE5R05A critical!).

For self-diagnosis, you can use a simple OBD-II scanner (for example, ELM327). The most common errors associated with automatic transmissions in Murano:

• 🔧 P0730 - incorrect gear ratio (often indicates wear of the clutches or pump).
• 🔧 P0740 — problem with torque converter locking.
• 🔧 P0841 — malfunction of the oil pressure sensor (typical for CVTs).

Automatic transmission maintenance: how to extend the life of the transmission

Automatic transmission resource in Murano directly depends on the quality and regularity of service. The manufacturer claims that the automatic transmission is filled with oil “for its entire service life,” but in practice this is not the case. Here are the key rules:

• 🛢️ Oil change: every 60,000 km for CVTs and 80,000 km for classic automatic transmissions. For RE5R05A It is better to reduce the interval to 50,000 km.
• 🔧 Filter: change along with the oil! In CVTs Murano the filter is often integrated into the pan and requires complete disassembly.
• 📊 Diagnostics: Once every 20,000 km, check the oil level and the presence of chips on the pan magnets.

To change the oil in an automatic transmission Murano It is recommended to use only original fluids:

• 🔴 For RE4F04B/RE5R05A — Nissan Matic S (article KLE52-00004).
• 🔴 For CVTs JF011E/JF017E — Nissan CVT Fluid NS-2 (article KLE52-00005) or NS-3 (for models after 2017).

⚠️ Attention: Never use generic type oils Dexron III or ATF+4! In CVTs Murano this leads to premature wear of the belt and cones. Also avoid "flushing" the box - they can wash away critical deposits and clog the solenoids.

What happens if you don’t change the oil in your Murano automatic transmission?

In classic automatic transmissions (RE5R05A) old oil leads to jamming of solenoids and wear of clutches. In CVTs (JF011E) - to belt slippage and destruction of cones. In both cases, repairs will cost 100,000+ ₽, while an oil change costs 5,000–10,000 ₽.

Automatic transmission repair Nissan Murano: when to go to service

Some automatic transmission problems can be solved on your own (for example, changing the oil or solenoids), but there are cases when professional repairs are indispensable. Here are the criteria for when it’s time to go to service:

• 🔧 The box “goes” into emergency mode (“Check Engine” lights up + “Hold” flashes).
• 🔧 Oil loss (more than 0.5 liters per 1,000 km).
• 🔧 Metal clanging or grinding when moving.
• 🔧 Complete loss of gears (the car does not move forward/backward).

The cost of repairs depends on the type of automatic transmission and the nature of the breakdown:

• 💰 Replacing solenoids — from 15,000 ₽ (excluding diagnostics).
• 💰 Major renovation (replacement of clutches, bearings, pump) - from 80,000 ₽.
• 💰 Replacing the variator assembly — from 200,000 ₽ (new) or 120,000 ₽ (contract).

When choosing a service, pay attention to:

1. Availability of diagnostic equipment (for example, Launch X431 or Bosch KTS).
2. Experience working with Nissan (especially with CVTs).
3. Warranty on work (at least 12 months).

CVT vs. classic automatic transmission: which is more reliable in Murano

Owners Murano They often argue which gearbox is better - a CVT or an automatic transmission. There is no definite answer, but we can highlight the pros and cons of each type:

Parameter	Classic automatic transmission (RE5R05A)	CVT (JF017E)
Resource (with proper maintenance)	250,000–300,000 km	200,000–250,000 km
Repair cost	Average (60,000–120,000 RUR)	High (RUB 80,000–200,000)
Acceleration dynamics	Worse (noticeable shifts)	Better (smooth acceleration)
Sensitivity to oil	Average	Very high

Our conclusion: if you plan to operate Murano in the city and often stuck in traffic jams, it is better to choose a model with a classic automatic transmission (RE5R05A). It is less whimsical and cheaper to repair. CVT (JF017E) is suitable for quiet driving on the highway, but will require more frequent maintenance.

Interesting fact: in Murano Z52 (2015+) CVT JF017E received reinforced cones and an improved cooling system, which increased its reliability by 20–30% compared to JF011E.

Do-it-yourself automatic transmission oil change Nissan Murano: step by step instructions

If you decide to save money and change the automatic transmission oil yourself, follow these instructions. It fits most models Murano, except CVTs JF017E (special equipment is required for a complete replacement).

You will need:

• 🔧 New oil (4–6 liters, depending on the replacement method).
• 🔧 Automatic transmission filter (article 31726-31X00 for RE5R05A).
• 🔧 Sealant for the pallet (for example, Loctite 574).
• 🔧 10 mm wrench and 24 mm socket (for drain plug).

Steps:

1. Warm up the machine to operating temperature (60–70°C).
2. Raise the front end on a jack or drive it into a pit.
3. Remove the crankcase protection (if equipped).
4. Unscrew the drain plug (24 mm wrench) and drain the old oil.
5. Remove the pan, clean the magnets from chips and replace the filter.
6. Install a new filter, pan gasket and fill in new oil through the dipstick.
7. Warm up the box (drive 5–10 km) and check the oil level to see if it is hot.

⚠️ Attention: In CVTs Murano You cannot drain the oil through the plug - you need to disconnect the automatic transmission cooling radiator pipes. Without experience, it’s better not to take risks!

FAQ: Frequently asked questions about automatic transmission Nissan Murano

Can it be towed? Murano with a faulty automatic transmission?

If the transmission is in emergency mode, towing is only possible with a rigid hitch or a tow truck. Maximum speed - 50 km/h, distance - no more than 50 km. For CVTs (JF011E/JF017E Towing is strictly prohibited - only tow truck!

What kind of oil to fill in automatic transmission Murano Z51 2010 with a 3.5 engine?

For RE5R05A only need to be used Nissan Matic S (article KLE52-00004). Analogs (for example, Idemitsu ATF Type-J) are allowed, but do not guarantee the same protection.

Why Murano with a CVT does it jerk when accelerating?

Most often this is due to wear on the belt or cones. Other causes: low oil level, dirty solenoids or faulty speed sensor. Check the oil immediately - if it is black and smells like burning, the variator needs repair.

How much does a contract automatic transmission cost? Murano Z50?

The price depends on the type of box: RE4F04B — from 30,000 ₽, RE5R05A — from 50,000 ₽. CVTs (JF011E) are more expensive - from 70,000 ₽. Before purchasing, be sure to check the box for hidden defects!

Is it possible to drive with an error? P0730?

Short-term - yes, but no more than 1-2 days. This error indicates problems with gear ratios, which can lead to complete failure of the automatic transmission. The most common culprit is a worn oil pump (RE5R05A) or solenoids.
