Don't look at gift horse's mouth. And if for this "horse" you pay the big money? Then that is necessary not what to look With to study, check, carp... About in what "teeth" it is necessary to glance, buying the second-hand car with an automatic box, the director of firm "Automatic Transmission Group" Vladimir Drozdovsky tells.

Don't look at gift horse's mouth. And if for this "horse" you pay the big money? Then that is necessary not what to look With to study, check, carp... About in what "teeth" it is necessary to glance, buying the second-hand car with an automatic box, the director of firm "Automatic Transmission Group" Vladimir Drozdovsky tells. Which repairs especially "successful" acquisitions.

All good, as it is known, - from laziness. If not laziness, what at us, at hardworking, now was? Anything would not be! Neither wheels, nor an electricity, a remote control. Especially - an automatic transmission. Because the normal driver not begins to facilitate to itself life in such doubtful ways - it will pull habitually and strainedly the switch handle. And only deeply lazy people at first have invented АКП, and now buy cars with "automatic machine". If you from their number then read further. However, we will make a reservation: time you are adjusted to "indulge" yourselves further with convenient management, are not lazy now, at car survey. Otherwise "the old woman with the automatic machine" will present to you many unpleasant surprises.

First of all it is necessary to understand with the years "old women". Average resource АКП makes 200-300 thousand in km or 10-15 years then the box really starts to grow old. While it does not affect its work, but will pass some months, and the new owner of such car with surprise will find out that on it have palmed off "much the best thing". Therefore about the first our prevention: buying the car with considerable run or is elderly about 10 years and more, it is necessary to be ready to that "automatic machine" long will not stretch.

In reduced service life АКП results also a sports way of driving, and also use of the car as the tractor (pay attention to presence of the towing device or traces of its installation). At purchase of such cars it is better to prefer cars with the touched transmission.

Thus it is desirable to learn, where she got over, what "illnesses" suffered, as it have repaired. Patiently see all papers and listen to stories of repairmen as to know the car biography - completely not superfluous.

But we will assume that you not the admirer of the restored veterans, you love "погорячее" and have chosen almost new (as the former owner assures) the car. How to estimate real condition АКП?

The first check. At the idle engine get щуп boxes and look at colour of oil. At run in 200 thousand in km oil should be dark brown and slightly transparent even if it never changed. And here dense black oil says that the box should be repaired. Do not forget also that in an automatic box it is impossible to change oil completely. Even if to remove the pallet and a cover of the block of valves, it is possible to replace only 50 percent (and 80 percent in "Mercedes" - as there are the second drain stopper in the hydrotransformer). Completely to replace oil in АКП, it needs to be disassembled. Therefore if you see on щупе not understanding АКП devstvenno-pure oil, be not under a delusion: "father" of your "bride" has obviously garbled cards.

Not bad to check up and oil level. Get the engine and, having walked by all positions АКП, establish the selector in position I RUB (or ТNУ With on cars of firm "Crysler" or front-wheel variants "Mitsubishi"). Then measure oil level on the minimum turns of idling. Too low or too high level says that the former owner of the car simply did not understand the technician: operation with wrong level of oil can lead to serious problems with АКП. However, do not forget that with heating (or cooling) oil level in a box essentially changes - to 50 mm. Necessarily check up, at least наощупь how much oil has heated up. Consider that щупы happen different: on one there are labels only for cold oil (+200С), on others With for hot (+60... 700С), and on the third With both those, and others.

The automatic box should react to all orders easily and easy. Start the engine, disconnect the conditioner, brake the car working brakes and translate selector AKP from position "N" serially in position "D" or "R". Thus, without a delay, there should be an inclusion of transfer to a little push forward or back.

If pushes appear strong do not hasten to accuse АКП of all mortal sins. The raised turns of idling of the engine, and also breakage of support of the power unit can be the reason of similar blows. But if you have noticed a delay of inclusion of transfer (more than 3-5 seconds), mean АКП is faulty. We will assume that the box has passed all previous tests successfully, it is necessary to sweep only. For this purpose it is necessary to choose an equal horizontal site of road. The car should get under way smoothly, without pushes and jerks, and to behave as at consecutive transition to higher transfers. However, jerks and pushes are not the main thing. Proslipping - here основный a sign faulty АКП. By sharp pressing an accelerator pedal at speed to 100 km/hour АКП it should be switched to lower transfer.

If there is a possibility, put the car on a viewing hole or the lift and look on АКП from below - whether there are no there oil smudges? Oil leaks, when to a box is obvious нездоровится.

But here there was of what you most of all were afraid. "Automatic machine" should be repaired. We will count up, such pleasure how many can cost. For a partition removed АКП without cost of spare parts you should pay from 300 to 800 dollars. The price depends on a place of repair, qualification of experts and guarantee certificates. Removal and installation АКП will manage to you in the sum from 150 to 600 dollars (complexity of operation, drive type etc.) . Will cost how many spare parts, to tell difficultly: a price range From 300-3.000 dollars depending on quantity of spare parts. In general, figures sad, also are said by them that is cheap you in any way will not get off. But you easily will expose the potboilers who with gross spelling mistakes repaired and have collected your car: such repair leads to failure АКП already in the first 2-3 days of operation. If on you have palmed off on a detail with latent defects (microcracks, porosity, manufacturing techniques infringement) will understand more difficult: these "surprises" are shown during 2-3 or even 2-6 months, and go understand, whether repairmen are guilty, whether you are not able to address with car.

Usually owners of repaired boxes (80 % addressing) throughout several months marked individual failures АКП. Then also there was a breakage in АКП instead of while the car has absolutely ceased to go. Therefore at occurrence of any short-term malfunctions necessarily address in specialised services on service and repair АКП. Start up you will be reinsured and once again will change oil. But it is much better, than to rise in any backwoods and not to know, what to do.

Some councils: at proslipping occurrence on any of transfers try to exclude this transfer from work АКП, operating a pedal of an accelerator and the selector of switching of modes. If the car does not get under way, remember what to tow the faulty car it is possible only at speed to 50 km/hour on distance of 50 km (the formula 50 х 50). In need of distant towage it is necessary to disconnect the driveshaft (semiaxes). And is better to tow such car with full loading.




We hope that you will not miss with purchase and last council long is not useful to you.
