Automatic transmission on Lada Granta (model JF414E) is considered quite reliable, but requires strict adherence to maintenance regulations. Unlike mechanics, where maintenance often comes down to checking the oil level, an automatic transmission is sensitive to the cleanliness of the working fluid and the condition of the filter elements. Ignoring this rule can lead to expensive repairs or complete replacement of the unit.
Many owners postpone the replacement procedure, relying on the manufacturer’s assurances that the oil is filled for the entire service life. However, in real operating conditions, especially in urban conditions with frequent traffic jams, the properties of the liquid degrade much faster. Granta automatic transmission filter becomes clogged with friction wear products and metal shavings, which interferes with oil circulation and leads to overheating.
In this article we will analyze in detail the process of replacing the filter element, choosing suitable consumables and nuances that are often silent about in official services. You'll learn how to extend the life of your transmission yourself, saving a significant amount of money.
⚠️ Attention: Before starting any work, make sure that the car is on a flat, horizontal surface and that the engine has completely cooled down. Working with hot oil can cause serious burns!
When is it necessary to replace the filter element?
The service life of an automatic transmission directly depends on the quality of the lubricant. Automatic transmission filter performs a cleaning function, trapping friction dust and metal shavings. Over time, the throughput of the mesh decreases, and the pressure relief valve opens a channel for unclean oil, releasing dirt directly into the valve body.
Official regulations may not contain clear instructions for frequent replacement, but experienced mechanics recommend carrying out the procedure every 40–60 thousand kilometers. If you notice that gear shifting has become less smooth, there are kicks or delays at start - these are the first signals that maintenance is needed.
- 🚗 The appearance of jerks or kicks when switching speeds, especially on a warm engine.
- 📉 Increased fuel consumption and transmission noise.
- 🔥 Overheating of the box during long driving or towing a trailer.
It is important to consider that Lada Granta With a mileage of over 80 thousand kilometers without an oil change, a sudden change of fluid can lead to slipping of the clutches. In this case flushing system is not recommended, it is better to perform a partial replacement and install a new filter.
Selecting Supplies and Tools
To perform the work efficiently, it is necessary to prepare the components in advance. Original filter on Granta with automatic transmission Jatco has article number 31397-01R00, however, there are many high-quality analogues on the market, which are often cheaper and more accessible.
The choice of oil should be approached responsibly. JF414E box requires standard fluid JWS 3309 (often labeled Type T-IV). Using an unsuitable fluid can lead to unstable operation of the solenoids and rapid wear of friction pairs.
List of compatible oils
Oils Mobil ATF 3309, Idemitsu ATF Type-TS, Aisin ATF JWS 3309, Shell Spirax S4 ATF X. All of them meet the required specifications and have proven themselves well in Russian conditions.
In addition to the main components, you'll need a new pan gasket (often sold with the filter) and sealant to ensure a good seal. Be sure to purchase brake cleaner to remove old dirt from the magnets and pan.

Preparing the vehicle for servicing
Before proceeding with the dismantling of the protection, the car must be driven onto an inspection hole or overpass. An alternative is to use jacks and reliable stands, since working while lying on the ground is extremely inconvenient and unsafe.
Allow the engine to cool after driving to avoid burns, but do not allow it to cool completely if you plan to check the level using the hot method (although this is not critical for a complete replacement). Remove the plastic crankcase protection, if installed, by unscrewing the necessary bolts.
☑️ Preparation for replacement
Be sure to prepare a container with a volume of at least 5 liters for used oil. Place a rag nearby in advance to immediately wipe down surfaces and avoid oil puddles on the garage floor. Cleanliness in the work area is the key to safety and convenience.
Removing the pan and old filter
The process begins by unscrewing the drain plug or, in the case of an automatic transmission Granta, with partial unscrewing of the pallet bolts. Since there is no separate drain hole here, the oil will have to be drained over the edge by carefully bending one side of the pan.
Unscrew the bolts around the perimeter of the pallet, leaving several corners slightly stuck. Place the container and carefully remove the last fasteners, allowing the oil to flow out in a stream rather than splashing. Be careful: the liquid may be hot and have an unpleasant odor.
⚠️ Attention: When removing the tray, watch out for the magnets that may be installed on its inner surface. Don't lose them and be sure to wash away any metal shavings.
After draining most of the oil, remove the pan completely. You will see automatic transmission filter Granta, which is mounted on three bolts and connected to the valve body through an O-ring. Carefully unscrew the fasteners and remove the old element.
Inspect the inside of the pan. The presence of large chips or aluminum chips may indicate serious wear of the clutches or bushings. In this case, simply replacing the filter may not solve the problem, and troubleshooting of the box will be required.
Installation of a new filter and assembly
Before installing a new filter, thoroughly clean the mating surface of the hydraulic unit and the pan itself. Use brake cleaner and lint-free rags. Make sure there are no traces of old sealant or gasket left on the surface.
Install the new filter into place, making sure that the O-ring is seated smoothly and without distortion. Tighten the filter mounting bolts with the recommended torque, without overtightening them to avoid damaging the threads in the aluminum housing.
When installing a new filter, lightly coat the rubber O-ring with fresh oil. This will ensure tightness and prevent the rubber from biting during installation.
Apply a thin layer of heat-resistant sealant to the grease-free surface of the pan (if using a gasket without an adhesive layer) or install a new gasket. Press the pan evenly against the automatic transmission housing and tighten the bolts crosswise for an even fit.
Having completed the installation of the mechanical part, you can proceed to filling in fresh oil. This is done through a control hole or probe (depending on the modification), but on Granta Most often, filling is done through the dipstick hole under the hood using a funnel and hose.
Oil level check and diagnostics
After adding oil, start the engine and let it idle. Warm up the gearbox to operating temperature (approximately 60–70 degrees) by switching the automatic transmission selector to all modes with a delay in each position.
The level is checked with the engine running. Unscrew the check plug (if any) or dipstick: the oil should drip slightly or be at the level of the “Hot” mark. If there is not enough oil, add more, if it flows in a stream, let the excess drain.
- 🔍 Check connections for oil leaks after assembly.
- 🚗 Drive the car, assessing the smoothness of the shifts.
- 🌡️ Make sure that the transmission does not overheat after the trip.
The correct oil level is checked only on a warm automatic transmission with the engine running. Underfilling or overfilling are equally harmful to the gearbox.
In the first kilometers after replacement, try to avoid sudden starts and slipping. Give new seals and filters time to adapt. If you did everything correctly, the box will operate smoothly and silently.
Frequently asked questions (FAQ)
Is it possible to wash the old filter instead of replacing it?
No, flushing the automatic transmission strainer is ineffective. Fine friction dust clogs the mesh cells from the inside, and it is almost impossible to wash it out. In addition, the filter material loses its properties over time. Only a complete replacement guarantees a clean system.
Which oil is better to pour: original or analogue?
The main thing is compliance with the specification JWS 3309. Original Nissan/Jatco oil is excellent, but high-quality analogues from Aisin, Mobil or Idemitsu are in no way inferior in performance and are often cheaper. Avoid universal oils labeled “for all automatic transmissions.”
Do I need to change the oil in the torque converter?
With a simple replacement through the pan, about 30-40% of the old oil remains in the torque converter (donut). To completely replace it, a hardware technique or repeated partial replacement is required. However, to extend the service life, regular partial replacement with filter updating is sufficient.
Why did kicks appear after the replacement?
If the oil was very old before the change, replacing it with fresh oil could change the friction coefficient of the clutches. It is also possible that the oil level is set incorrectly. In some cases, it is necessary to adapt the box by resetting the battery terminal or driving in a certain mode.
