Automatic transmission on the car Skoda Octavia A5 with engine 1.6 MPI The Aisin TF-60SN is a reliable unit, but requires regular maintenance. Many owners mistakenly believe that the oil in the box is filled for the entire life, however, this is a myth that can lead to expensive repairs. A critical element of the lubrication and hydraulic control system is the automatic transmission filter, which over time is clogged with friction wear products and metal shavings.
Ignoring the filter replacement causes pressure to drop in the hydraulic unit, causing jerks, kicks and delays when switching speeds. Nana 1.6 MPI With a classic hydraulic transformer, the filter replacement process has its own features that differ from robotic DSG boxes. In this article, we will discuss in detail what filters exist, how to change them correctly and what to look for when choosing spare parts.
Types of filters and their design on Aisin automatic transmission
On the gearbox Aisin TF-60SN, installed on Skoda Octavia A5There are two filtering systems that are often confused by beginners. The first is an external rough cleaning filter that is attached to the gearbox crankcase and catches large debris. The second is an internal thin filter located directly inside the crankcase pallet, which filters the oil before entering the hydroblock.
An external filter is usually a mesh element that can be simply washed, but it does not trap small particles. The internal filter is a replaceable element that has a paper or synthetic filter material. It is his condition that directly affects the operation of solenoids and the stability of switching. With each planned oil change, it is recommended to change the internal filter, since its throughput drops sharply over time.
It is important to understand that the external filter does not replace the internal filter, and their functions are different. If you have only replaced the outer mesh but left the old paper element inside, the oil pressure problem will persist. For full maintenance, it is necessary to dismantle the crankcase pallet, which gives access to both filtration elements.
Original vs. Analogues: How to Choose a Quality Filter
Spare parts market for Skoda Octavia It is oversaturated with suggestions, and choosing the right filter can be a headache. The original filter from Skoda/VAG has a catalog number 09G327350B (or modifications thereof) that provide perfect fit and filtration quality. However, the price of the original is often overpriced, which encourages owners to look for alternatives.
- π οΈ Degree of filtration: The original and qualitative analogues have porosity, designed to retain particles of 10 microns in size, which is critical for thin channels of the hydroblock.
- π οΈ Quality of seals: The rubber gaskets on the original filter donβt tan in the cold, while cheap ones can flow thousands of miles away.
- π οΈ Compatibility: Make sure the filter is suitable for the box. Aisin TF-60SNNot for the CVT or DSG, as the mounts may differ.
Among the verified analogues, brands are often distinguished Feliks, SCT and Febi. They offer a good value for money, using materials close to the original. However, when buying, be sure to check the integrity of the packaging and the presence of labeling. A poor quality filter can crumble inside the box, which will lead to catastrophic consequences for the hydraulic transformer.
β οΈ Warning: Never install a filter without first cleaning the seat in the pallet. Even the smallest speck of dust can break the tightness and lead to leakage of oil.

Preparation for replacement and necessary tools
The process of replacing the filter 1.6 MPI It requires careful preparation, as the work is carried out in a limited space under the car. You will need a set of keys, preferably with extension cords, since the bolts of the pallet mounting are often in hard-to-reach places. You also need a jack or lift to access the bottom of the car.
In addition to tools, it is necessary to prepare consumables. In addition to the filter itself, you will need a crankcase pallet (or a quality sealant if the gasket does not come complete with the filter). You will also need a new transmission oil that meets the specification. VW TL 52162 (usually G 055 025 A2). The volume of oil that needs to be drained and added is about 4-5 liters when replacing the filter, since part of the liquid will remain in the hydraulic transformer.
- π§ Head set: The main dimensions are 8, 10, 13 mm, and Torx T25 for pallet bolts.
- π§ Drain tank: A minimum of 6 liters to collect the whole waste oil.
- π§ Carburettor cleaner: For washing the pallet and magnets from metal shavings.
Donβt forget to prepare your gloves and rags. Automatic transmission oil has a specific smell and is poorly washed off the skin. Before starting work, make sure that the car is on a flat surface and is reliably fixed. Working under a car without insurance is strictly prohibited.
βοΈ Preparing to replace the filter
Step-by-step instructions for replacing the automatic transmission filter
The first step is to warm up the gearbox to an operating temperature of about 50-60 degrees. This is necessary in order that the oil becomes less viscous and better blended, carrying with it the products of wear. After that, turn off the engine, install the car on the lift and fix it.
Remove the engine crankcase protection if it is installed. Substitute the drain tank under the pan of the gearbox and gently unscrew the drain plug. Let the oil drain completely. Then, unscrew the slacks of the slack. It is better to start with the lower, gradually moving to the upper, so that the pallet moves evenly.
When you remove the pallet, you will see an old filter. It's mounted on two bolts. Unscrew them and carefully remove the filter, trying not to spill the remaining oil. At this stage, carefully examine the inside of the pallet. There must be magnets that collect metal shavings. If you see a lot of shiny particles or large shards, thatβs a bad sign.
Carefully clean the magnets from shavings with rags and a cleaner. Wash the pan of the crankcase from the inside, removing all the sludge. Install a new filter after checking it for damage. Tighten the filter mount bolts with the recommended moment so as not to break the thread in the aluminum box case.
Install a new pallet pad or apply a thin layer of sealant if the pad is not provided. Tie the pallet in place, observing the sequence of tightening of the bolts. Pour new oil through the level sensor or probe hole (depending on the modification).
What do we do with the magnets?
The magnets in the automatic transmission pallet play a critical role in collecting metal shavings. When replacing the filter, make sure to clean them. If the magnet is covered with a thick layer of "metallic porridge" (sludge), this indicates a strong wear of friction linings. In this case, simply replacing the filter may not save the box from breakage in the future, and a deeper diagnosis of the hydraulic transformer and planetary rows will be required.
Oil Level and Work Check After Replacement
After installing a new filter and pallet, you need to adjust the oil level correctly. This is the most important stage. Start the engine and turn on all gears in turn, lingering on each for a few seconds. This will allow the oil to fill the hydraulic transformer and channels of the hydraulic unit.
The oil level is checked at the engine running and the oil temperature is about 30-50 degrees. The oil should flow out of the control hole when you unscrew the plug. If the oil doesn't flow, add it. If it flows with a strong pressure, then overflowed, and you need to drain the excess through the drainage hole.
β οΈ Warning: Errors in checking oil levels can lead to foam in the box (if poured) or oil starvation (if not poured). Both scenarios are detrimental to automatic transmission.
After setting the level, drive a few kilometers by car. Pay attention to the behavior of the box: jerks should disappear, switches should become smooth. After 100-200 kilometers of run, it is recommended to repeat the check of the oil level, since the new filter will absorb some of the liquid.
Keep checks for the purchase of oil and filter, as well as the date of replacement. This will be useful when reselling a car or tracking service intervals.
Typical problems and their signs
If after replacing the automatic transmission filter there are still jerks or kicks, the reason may lie not only in the filter. Perhaps the problem is in the solenoids of the hydroblock, which are jammed due to dirt, or in the hydrotransformer itself. It is also worth checking the wiring and connectors of the speed sensors, as a fault in the electrician is often masquerading as mechanical problems.
Another common problem is leakage of oil at the joint of the pallet. This happens if the gasket is mounted curved or if the bolts are tightened unevenly. Carefully inspect the car after the first trip. Even a small puddle under the car can indicate a serious loss of oil pressure.
| Symptom of malfunction | Possible reason | Recommended Action |
|---|---|---|
| Switching jerks 1-2 and 2-3 | Clogged filter, low pressure. | Changing the filter and oil |
| humming | Worn bearings or torque converter | Diagnosis by a specialist |
| Black-coloured butter in a pallet | Burnt oil, friction wear | Complete oil and filter replacement |
| Leaking from under the pallet | Incorrect gasket installation | Re-mounting the pallet with a new gasket |
Owners sometimes find that the new filter is not suitable for mountings. This happens when buying non-original spare parts with the wrong article. Always check the part number with your carβs VIN code before buying. Mistaking a part selection can cost you time and money to re-work.
Regularly changing the filter and oil is the cheapest way to extend the life of automatic transmissions by 100,000 km or more without major repairs.
FAQ: Frequently asked questions
How often should I change the filter to Octavia A5 1.6?
It is recommended to change the filter with the oil every 60,000 kilometers or every 4 years, whichever comes first. In aggressive driving style, the interval should be reduced to 40,000 km.
Can you just wash the old filter and put it back?
No, washing paper or synthetic filter is ineffective. Microparticles clog the pores of the material, and the throughput is not restored. The filter is a disposable element and must be replaced.
How much oil does it take to change with filter?
When replacing the filter, about 4-4.5 liters of oil are drained. It will take about 6 liters to refuel fully, as some of the liquid remains in the hydraulic transformer. It is better to buy a canister of 5 liters and add 1 liter.
Should I change the whole pan of the crankcase?
In most cases, it is enough to replace only the filter and pad pallet. However, on some models, the pallet is assembled with a filter. For Skoda Octavia A5 With Aisin automatic transmission, the filter is usually changed separately, and the pallet is cleaned and used with a new gasket.
