Undoubtedly, the convenient and increasingly common on modern passenger cars automatic variable transmission or "automatic", belongs to the category of units that should be considered:
- Structurally complex.
- Fairly expensive compared to mechanical counterparts.
- Costly to repair or replace in case of unexpected (non-warranty) breakdown.
- Mandatory for checking the technical condition and carrying out scheduled maintenance.
And if changing the engine oil has become for most motorists (including those belonging to the beautiful half of humanity) a completely understandable and reasonable regularity of the procedure, then many have not even heard of the fact that it is also carried out for automatic transmission. At the same time, the choice of the oil itself ( in more detail you can get acquainted with the types on the supplier's website) requires a more careful approach and this should be discussed in more detail .
When and how to change oil in automatic transmission
The speed and effort of the torques arising in the automatic transmission are comparable to the similar physical loads generated in the power unit. The only difference is that there are no high temperature values, which is why the oil in the automatic transmission changes much less often. On average, for most cars, the procedure is carried out after 70 thousand kilometers. In any case, when passing MOT at a dealer or in a service center before the specified parameter, it is necessary to demand (the service is included in the cost of a preventive inspection and you do not need to pay for it) from the mechanic:
- Checking the automatic transmission oil level.
- Inspection of the condition of the lubricating fluid on the dipstick (absence of metal inclusions or characteristic burnt color).
It is clear that in order to reduce the cost of the oil change procedure in the "machine", it is best to purchase it from the supplier at a more affordable cost. This type of lubricant is much more expensive than a motor analogue (this should be taken into account when choosing).
A question of originality
High-quality and original oil, poured into the automatic transmission when replacing, will ensure smooth starting and shifting during vehicle operation. And most importantly, it guarantees the serviceability of the unit for several more years of intensive work. Before using the online catalog of its supplier for purchase, you should carefully study the technical passport of the car. In it, the manufacturer (an obligatory item in any reference book) indicates:
- Type, make, brand of oil filled into the automatic transmission crankcase at the factory for this model.
- The amount (volume) of lubricant required for replacement.
- Article number and product classification.
