Oil change in automatic transmission Nissan Pathfinder R51

The cost of a complete oil change in the Nissan Pathfinder R51 automatic transmission at the service will cost 11-12 rubles, including all consumables. The process of replacing the fluid itself is simple, so the work can be done independently. The frequency of replacing ATF in an automatic transmission depends on the driving style, the operating conditions of the machine and the quality of the lubricant itself. In addition to the new transmission fluid, you will need a tool, consumables and instructions so as not to forget about some of the nuances.

Transmission oil change interval

Nissan Pathfinder with body index R51 was produced from 2005 to 2014. In this generation, the 5-speed Jatko RE5R05A was available in automatic machines - phlegmatic and reliable. This automatic transmission does not like aggressive acceleration, which quickly wears out the torque converter lockup and contaminates the lubricant. The friction suspension wears out the channels of the valve body, clogs the spools, as a result of which the pressure in the clutch packs drops.

According to Nissan regulations, it is necessary to check the condition and fluid level in the car every 15 km or once a year. Lubrication intervals: every 000 km or every 60 years, whichever comes first. If the machine is used to tow a trailer, drive in the desert or on muddy roads, the automatic transmission lubrication period is reduced to 000 km.

Masters recommends changing the oil in your Nissan Pathfinder as soon as it becomes clear and not thick. Timely maintenance will extend the life of the valve body and delay the overhaul of the box by 300 km. Fans of aggressive driving are advised to monitor the operation of the torque converter and remove blockages in time, without waiting for the machine to fail.

Practical advice on choosing oil in an automatic transmission Nissan Pathfinder R51

When choosing oil in a Nissan Pathfinder automatic transmission, follow the manufacturer's recommendations. The electronics and solenoids in each box are tuned for a particular type of fluid, so filling with a more viscous or fluid lubricant will cause the system to malfunction. Buy ATF from authorized dealers to avoid fakes.

Checking the level

On an early Nissan Pathfinder car (until 2010), the oil level in the automatic transmission is checked with a dipstick. For the test, you will need white paper. The temperature of the "hot" liquid should be +65℃.

Check sequence:

1. Warm up the engine and automatic transmission by moving the selector to all positions.
2. Stop the vehicle on a level surface and apply the parking brake. Leave the automatic transmission lever in the "P" position. The engine is idling.
3. Inspect the bottom for fluid leaks.
4. Find the dipstick under the hood. Loosen the mounting bolt.
5. Remove the dipstick and clean it with paper.
6. Re-insert the dipstick into the filling tube by turning it 180℃ from the normal position until the cap touches the edge of the tube.
7. Remove the dipstick and take readings from the face of the scale Hot - the indicator is within the upper mark.
   

   If the level is well below the upper mark, add ATF through the filler neck. Heat fluids and check level.

1. Check the condition of the lubricant: a good oil should be transparent, clean, without the smell of burning and broken particles. If there is a strong pollution or smell of burning, you should replace the fluid and check the internal condition of the automatic transmission.
2. After checking the level, replace the dipstick and tighten the bolt.

In the Nissan Pathfinder after 2010, the dipstick was removed. To check the ATF level, you need to get under the car and unscrew the plug. Required fluid temperature +40℃. Follow the scanner's prompts or your gut. General verification algorithm:

1. After warming up the automatic transmission, unscrew the filler plug of the pan.
2. If the fat has flowed out, the level is normal. If it is dry, fill it with a syringe or gravity feed.

Materials for a comprehensive oil change in automatic transmission Nissan Pathfinder R51

A complete ATF replacement in an automatic transmission involves flushing the pan, cleaning or replacing the filter. For work you will need:

• fresh liquid in a volume of 4 - 5 liters with a partial and 12 - 15 liters with a complete replacement;
• funnel with a hose 12 mm long 1,5 - 2 m;
• syringe;
• set of tools;
• sludge drainage capacity;
• kerosene, gasoline or carburetor cleaner to clean the pan and filter;
• new pan gasket: art. 31397-90X0A for engine 2.5, art. 31397-1XJ0A for 3.0 engine;
• filter (if necessary) art. 31728-97×00;
• drain plug gasket;
• work clothes, gloves.

Self-changing oil in an automatic transmission Nissan Pathfinder R51

Before changing the automatic transmission oil for a Nissan Pathfinder R51, study the manuals yourself to remember the location of all positions and clarify the manufacturer's recommendations. Prepare tools and materials. Heat up the motor and fluid in the housing to 40 - 65℃, depending on the type of machine.

Draining old oil

We will drain the lubricant from the automatic transmission through a plug in the pan, so we put the Nissan Pathfinder R51 on a lift or a pit. Stop the engine. Remove the crankcase protection to gain access to the sump. Drain all the liquid into the container, as we will fill the same volume:

1. Unscrew the drain bolt and place a container for draining. Remember ATF is hot!
2. Will pour out about 4 liters.
3. Loosen the oil pan bolts. Be careful, hot oil will pour out, another 0,5 - 1,0 liters!
4. Remove the tray. If you do not plan to clean the sump, tighten the plug with a new gasket and a torque of 34 Nm.

Pallet rinsing and swarf removal

If the pallet is dented, replace the part; if not, wash away dirty oil and shavings:

1. Inspect the magnets for chips and large particles.
2. Clean the old cover gasket.
3. Wash the sump with kerosene or carburetor cleaner, clean the magnets.
4. Degrease the mating surface of the cover and install a new gasket.

After replacing the filter, install the pan by tightening the bolts to 7,9 Nm. Tighten the drain bolt with a new rubber band to 34 Nm.

At the next stage of changing the automatic transmission oil in the Nissan Pathfinder, we will fill in a new fluid.

Filter replacement

The Nissan Pathfinder automatic transmission has an open metal mesh filter. With a calm driving style - when the ATF does not age for a long time and does not smell burnt - it is not necessary to change it, it is enough to rinse with gasoline so that the filter is clean. In this mode, the part passes its resource of 250 km. If the transmission is operated under severe conditions, the mesh may break or become clogged with dirt, resulting in shifting problems.

To remove the filter, unscrew 18 bolts. Inspect the screen: the presence of chips indicates wear of automatic transmission parts. Wash the filter in all corners and replace it.

Filling in new oil

To fill the automatic transmission oil in the Nissan Pathfinder R51 until 2010, use the dipstick under the hood. There are no problems here - we fill in a new liquid with a hose and a funnel into the drained amount, warm up the box and check the level.

On Nissan Pathfinder facelift models, the fill port is located on the crankcase cover. It is a volumetric flask, through the upper cut of which liquid must be supplied. To fill with fresh ATF, install the dispenser. The device is made of a hose with an adapter or a sleeve with a lock nut. The thread of the accessory should be like in a cork.

Now pump the oil under pressure with a syringe. Or run the hose through the engine compartment to the engine compartment. Place a funnel at the top of the hose and add new grease until the amount is drained or until the excess runs out of the hole.

When heated, the liquid expands in volume, so add 0,5 liters of oil to compensate for splashing. Start the engine for 5 minutes and warm up the automatic transmission by moving the selector through all positions. Then excess fat will flow out and the level will normalize.

Complete replacement of transmission fluid in automatic transmission

A complete automatic transmission oil change in the Nissan Pathfinder is done by displacing the old fluid. The best option would be to alternate full and partial replacements so that the box stays clean at minimal cost. If you want to switch to another manufacturer's ATF, also use the full displacement method so that the oils do not mix in the car.

Preparatory work is the same as for partial replacement, in addition, an assistant is needed:

1. Let the engine idle to allow the automatic transmission oil pump to pump fluid.
2. Pour fresh ATF through a funnel while draining old ATF through the exhaust side oil cooler hose. Pour until the color of the drained and poured liquid is the same.

When the engine is running, a lot of pressure is created, so the drain tank will be filled with “torque”. Use a large container or pour in portions.

A complete replacement will require 12 to 15 liters of new oil.
