Automatic transmission filter <em>Nissan Patrol Y62</em>: when to change, which one to choose and how to replace it yourself

Nissan Patrol Y62 - a legendary SUV, famous for its reliability, but even its automatic transmission RE7R01A requires timely maintenance. One of the key elements of the system is automatic transmission filter, which many owners underestimate. Meanwhile, a dirty filter leads to jerking when switching, overheating of the oil and accelerated wear of the clutches. In this article we will look at how to determine the need for replacement, which filters are suitable for Y62, and is it possible to cope without a service station?

Standard regulations Nissan requires changing the automatic transmission oil every 60–90 thousand km, but the filter is often left unattended. Meanwhile, its service life depends not only on mileage, but also on operating conditions: towing, off-road conditions or frequent traffic jams reduce its service life by 1.5–2 times. If you ignore replacement, the consequences will cost many times more - from jamming of solenoids before overhaul of the box.

Signs of a clogged automatic transmission filter Patrol Y62

Filter in automatic box Y62 performs two functions: it catches metal shavings and friction wear products, and also prevents the circulation of dirty oil. When it becomes clogged, the symptoms appear gradually, and many attribute them to “features of the automatic transmission.” Pay attention to the following signals:

• 🔴 Jerks when switching - especially noticeable when cold or during sudden acceleration. This is due to a drop in oil pressure due to a clogged filter.
• 🔴 Switching delays (1–2 seconds) — the box “thinks” before engaging the gear, since the valve body does not receive enough lubrication.
• 🔴 Extraneous sounds — a hum or whistle from the automatic transmission area indicates oil starvation of the bearings.
• 🔴 Box overheating - if the oil temperature exceeds 100°C, the dashboard may light up AT TEMP.

It is important to distinguish the symptoms of a clogged filter from faulty solenoids or worn clutches. For example, if jerking appears only when it’s hot, the problem is most likely in the oil or valve body. But constant delays when switching from 1st to 2nd gear - a classic sign of a clogged filter.

⚠️ Attention: If metal shavings are visible on the automatic transmission dipstick or the oil smells like burning, the filter will no longer help - diagnostics of the gearbox is required. In this case, replacing the filter without flushing the valve body may worsen the problem.

Replacement timing: when to change the automatic transmission filter Patrol Y62

Official regulations Nissan does not indicate a specific filter replacement interval - it is considered a “consumable for its entire service life.” However, the owners' experience Y62 shows that this is nothing more than a marketing ploy. Actual timing depends on:

• 📌 Oil type — synthetics last longer than mineral water, but quickly washes away deposits that clog the filter.
• 📌 Operating conditions — in a city with traffic jams or off-road, the filter wears out 2 times faster.
• 📌 Driving style — aggressive acceleration and towing a trailer accelerates wear of the clutches, which means filter contamination.

Optimal replacement intervals:

Operating conditions	Recommended mileage	Notes
Calm ride, highway	80–100 thousand km	The filter may last longer, but the oil still requires replacement every 60 thousand km.
City (traffic jams), light off-road	50–70 thousand km	It is recommended to check the condition of the oil every 30 thousand km.
Aggressive driving, towing, deep off-road	30–50 thousand km	The filter and oil are changed at the same time, preferably with flushing the pan.

If you purchased Patrol Y62 with mileage and do not know the service history, it is better to replace the automatic transmission filter immediately, even if the oil looks clean. The previous owner could add fresh oil before selling it without touching the filter.

Original filters and analogues: what to choose for Y62

For Nissan Patrol Y62 with box RE7R01A Several types of filters differing in design and material are suitable. Original art from Nissan — 31726-31X0A (for models up to 2017) and 31726-31X0B (after restyling). However, their price is often inflated, and high-quality analogues are cheaper.

When choosing a filter, pay attention to:

• 🔧 Filter element material - optimal impregnated cellulose or synthetic fiber. Cheap paper filters clog quickly.
• 🔧 Presence of magnets — they catch metal shavings, prolonging the life of the box.
• 🔧 Compliance with sizes — non-original filters may not fit tightly to the pan, which will lead to air leaks.

The best analogues of the original filter:

Brand	Article	Price (approx.)	Features
JS Asakashi	FS10003	1 200–1 500 ₽	High quality cellulose, magnets included.
Zekkert	OF3306	900–1 100 ₽	Budget option, suitable for planned replacement.
Febi	28316	1 400–1 700 ₽	Improved filtration, recommended for harsh conditions.
Mannol	MN7906	800–1 000 ₽	Good price/quality ratio, but without magnets.

If you are choosing between the original and the analogue, keep in mind that Nissan often orders filters from the same manufacturers (for example, JS Asakashi or Aisin). The only difference is the packaging and price. The main thing is to avoid no-name brands, since their filters can spread due to high temperatures.

Step-by-step instructions for replacing the automatic transmission filter

Replacing the filter with Patrol Y62 does not require special equipment, but will require skill and tools. If you have never worked with an automatic transmission, it is better to entrust the procedure to specialists - errors during assembly can lead to oil starvation boxes. To replace it yourself, prepare:

• 🔧 Set of sockets and keys (10 mm, 14 mm, 17 mm).
• 🔧 Sealant for pallet (Loctite 574 or similar).
• 🔧 New filter and pan gasket (31397-31X00).
• 🔧 6–8 liters of oil Nissan Matic S (or equivalent Idemitsu ATF Type-J).
• 🔧 Container for draining waste (minimum 5 l).
• 🔧 Funnel with a long hose for pouring oil.

The replacement process takes 2–3 hours. Follow the instructions:

1. Drain the old oil:

   Warm up the box (drive 5–10 km), then turn off the engine. Unscrew the drain plug on the pan (key 17 mm) and drain the oil. It will be hot - use gloves!

2. Remove the pan:

   Unscrew all pan bolts (head 10 mm) and carefully remove it. Be prepared for ~0.5 liters of oil remaining.

3. Replace the filter:

   Unscrew the 3 filter mounting bolts (wrench 14 mm), remove it and install a new one. Check that the O-ring is seated tightly.

4. Clean the tray and magnets:

   Wash the pan with gasoline or kerosene, remove metal shavings from the magnets. Remaining dirt can re-clog the filter.

5. Replace the tray:

   Apply a thin layer of sealant to the gasket, screw the pan, tightening the bolts crosswise (torque 10–12 Nm).

6. Fill with new oil:

   Fill in ~5.5 liters of oil through the filler neck (next to the dipstick). Warm up the box, check the level on the dipstick and add if necessary.

Start the engine and warm up the automatic transmission to 60–70°C|Check the oil level on the dipstick (should be between MIN and MAX)|Drive 5–10 km and check the level again|Make sure there are no leaks under the pan|Listen to the box for any extraneous noise-->

⚠️ Attention: If, after replacing the filter, the transmission begins to jerk or the gears do not engage, you may have overtightened the pan bolts or installed the filter incorrectly. In this case turn off the engine immediately and check the assembly.

Common mistakes when replacing an automatic transmission filter

Even experienced car owners make mistakes that later lead to serious damage. Here are the most common:

• ❌ Saving on oil — filling with cheap analogues instead Nissan Matic S or Idemitsu Type-J leads to foaming and loss of properties at high temperatures.
• ❌ Insufficient sump flushing - if you do not remove the old dirt, it will immediately clog the new filter.
• ❌ Re-tightening of pallet bolts - this deforms the gasket and leads to leakage. The tightening torque should not exceed 12 Nm.
• ❌ Ignoring magnets - If the magnets are not cleaned or reinstalled, metal shavings will circulate throughout the system.
• ❌ Incorrect oil level - both lack and excess of oil are harmful. If there is a deficiency, the bearings suffer; if there is an excess, it foams and loses its properties.

Another common mistake is Changing the filter only without oil. ~30% of the old oil remains in the box, which mixes with the new one and reduces its properties. If you decide to change the filter, be sure to follow complete oil change (with a change of 2-3 servings).

What happens if you don't change the automatic transmission filter?

At first you will notice smooth symptoms: twitching when switching, delays. Then accelerated wear of the clutches and solenoids will begin. In critical cases, the box goes into emergency mode (AT TEMP on the panel), and then - complete failure with the need for major repairs (from 150 thousand rubles for RE7R01A).

Do I need to flush the automatic transmission when replacing the filter?

Flushing an automatic transmission is a controversial issue. Official dealers Nissan It is not recommended to carry it out, citing the risk of washing out useful deposits. However, in some cases flushing is necessary:

• ✅ The box is heavily soiled (black oil, with a burning smell).
• ✅ There are a lot of metal shavings in the oil (visible on the tray magnets).
• ✅ The car was used in difficult conditions (off-road, towing).

If you decide to rinse, use only specialized liquids (For example, Liqui Moly ATF Reiniger or Wynns TransCleaner). It is strictly prohibited:

• 🚫 Flushing with kerosene or diesel fuel destroys the seals.
• 🚫 Use “five-minute” washes - they are aggressive and can damage the clutches.
• 🚫 Rinsing the box if the oil is in normal condition is an unnecessary risk.

Alternative to washing - double oil change:

1. The old oil is drained and new oil is added.
2. You drive 500–1000 km.
3. Drain the oil again and add fresh oil.

This method is gentler and safer for the box.

Cost of replacing an automatic transmission filter: service station vs independently

Filter replacement price Nissan Patrol Y62 varies depending on the region and service station level. On average:

Service	Cost (₽)	Notes
Filter replacement + oil (partial)	8 000–12 000	Includes 4-5 liters of oil and labor.
Filter replacement + complete oil change (hardware)	15 000–20 000	A washer is used and 100% of the oil is replaced.
Automatic transmission diagnostics before replacement	1 500–3 000	Recommended if a malfunction is suspected.
Self-replacement (materials)	5 000–7 000	Filter (1,500 ₽), oil (3,500–4,500 ₽), gasket (500 ₽).

Replacing it yourself is cheaper, but requires time and tools. If you are not confident in your abilities, it is better to turn to specialists. Pay attention to reviews of service stations - a poor-quality filter replacement can result in a box repair.

When choosing a service, please specify:

• 🔹 What kind of oil do they use (must be Nissan Matic S or certified equivalent).
• 🔹 Do they change the pan gasket (sometimes they “save” it and install it on the old sealant).
• 🔹 Do they provide a guarantee for the work (good service stations guarantee 1-2 months).

FAQ: Frequently asked questions about the automatic transmission filter Nissan Patrol Y62

Is it possible to drive with a clogged filter if there is no money to replace it?

It’s possible for a short time (1–2 thousand km), but it’s not worth the risk. A clogged filter leads to oil starvation, which accelerates wear of clutches and solenoids. If your budget is limited, at least change the oil - this will temporarily improve the situation.

How to check the condition of the filter without removing the pan?

Directly - no way. Indirect signs: dark oil with a burning smell, metal shavings on the dipstick, jerking when switching. If in doubt, remove the pan - this is the only reliable way to diagnose.

Is the filter suitable for Nissan Navara on Patrol Y62?

No, it doesn't fit. U Navara (with box RL7R01B) another filter (31726-1X000). Even if they look similar, the difference is in the fastenings and throughput.

How much oil should I fill after replacing the filter?

With a partial replacement (without flushing), ~5.5–6 liters will be required. The exact volume depends on how much oil is left in the torque converter. After replacing, warm up the box and check the level using the dipstick.

Is it possible to wash the old filter and install it back?

Technically possible, but not recommended. The filter element loses its properties after washing, and the metal mesh may become deformed. It’s better to spend money on a new filter - its price is not comparable to the cost of repairing an automatic transmission.
