Whether it is possible to tow the car equipped car with "automatic trancemission"?


It is possible - having established the selector in position "N" and strictly adhering to restrictions of range and the speed, usually resulted in the instruction. If they are not specified, use the formula "50х50", that is be towed on distance to 50 km with a speed not above 50 km/h. In need of more distant towage is better to separate transmission. Such measure as having added superfluous oil in a box, to some extent will help, but considerably position will not improve. The matter is that its some elements are greased under pressure from the hydropump - to them oil will not get самотеком even at the raised level. If the engine has kept working capacity, safely start up it and be towed (also on "neutral"), gasoline will not come to an end yet. If the motor does not work, but the starter is serviceable, it will be useful to include it each 10-15 kilometres for 8-10 seconds. Some models of cars were in addition equipped трансмиссионным with the pump earlier - restrictions on towage do not concern them. Besides, it gave the chance start-up "from a pusher" that at more modern cars with "automatic machine" it is impossible.

- How to prolong life to an automatic box?

- The general rule: the more easy you go, the the box will long serve. As most tensely it works during the gear change moments at intensive dispersal, having accustomed and having learnt them to foresee, try hardly to dump before them gas. At a total load of the car or towage of the heavy trailer it is possible to recommend dispersal till speed of kilometres forty at an o'clock at position of the selector "1", and then switching in a mode "D". If there was a refusal, let individual, it is better to address at once to experts. The further operation can aggravate malfunction - then repair will appear repeatedly more expensively.

- What oils are used in "automatic machines"?

- Only mineral oils of series АTF, usually marks "Deksron" (Dexron) with various numerical indexes. All of them of red colour also suppose mixing in various proportions. Them "ходимость" - a minimum of 50-70 thousand kilometres, the price - from three to nine dollars for litre. In a car box fill in 6-9 l, and here it will be necessary for all-wheel drive "Ford-Bronko" all 18. Recently, especially by the French cars, use oils of yellow and green colour. To mix them with "Deksronom" it is inadmissible! It is undesirable to add in oil and any restoring additives. From it we did not meet real positive results, and here the boxes ruined by different additives came across from time to time.











Automatic transmission "Borg-Uorner-35":
1 – a turbine wheel; 2 – a pump wheel; 3 – a reactor wheel; 4 – a reactor shaft; 5 – a primary shaft of a planetary reducer; 6 – the main oil pump; 7 – a friction clutch II and III transfers; 8 – a brake I and II transfers; 9 – a friction clutch of III transfer and backing transfer; 10 – муфта a free wheeling of I transfer; 11 – a backing brake; 12 – the first intermediate shaft; 13 – the second intermediate shaft; 14 – a drum with a gear wreath; 15 – a centrifugal regulator; 16 – a secondary shaft; 17 – the gear change mechanism; 18 – the throttle valve; 19 – a cam.

- Whether it is possible to repair an automatic box independently?

- In general - yes if the cause of a failure (for example, deterioration of friction clutches because of shortage of oil is clear). But "automatic machine" - the unit difficult and is much more often the reason insufficient pressure in any highway can, for example. Thus "opening" about what will not tell to the nonspecialist. Repair, namely malfunction diagnostics is most combined not.

- Where in that case to repair?

- The most expensive variant - in firm service where a faulty box, most likely, will replace restored or new. Its cost depending on model - from three to nine thousand dollars plus payment of work and sometimes - a minus residual cost of the faulty unit.

Other variant - repair in small firm at which choice it is necessary to consider that, as a rule, tells versatility about low professional level. Such firms, ready to undertake any work, it is a lot of - in one Moscow ten ones and a half. But doing really high-quality repair and specialising only on automatic boxes - only three-four. Quotations in them are that: removal - "automatic machine" installation - 300-600 dollars, repair - 400-1000, spare parts for repair of average volume - 500-1000.

The third, well-known variant - repair at any garage "uncle Vasi". Quality and quotations here at times are any, and the bottom lath - at level of three hundred-four hundred dollars. For the owner such repair can turn back a headache. Recently to us have driven the car which box has already visited hands "умельца". Because of wrong assemblage the most expensive part of the unit has become unfit for use - has burst картер, and repair has managed twice more expensively than if have addressed to experts at once.

At last, it is possible to buy for replacement "бэушный" the unit for one thousand-one and a half dollars. But be ready to that it can appear even worse yours. And let will not mislead fresh "серебрянка" by which everything is covered, up to rubber consolidations - so "restore" the boxes taken from automobile dumps more often.

- How will long serve "automatic machine" after repair?

- Touched at experts - ненамного new, 120-150 thousand kilometres.

- Whether it is possible to replace an automatic box with the mechanical?

- This operation is rather difficult, though basically is possible. To replace the car on similar with "mechanics" easier.

- What features of boxes of various marks of cars?

- All automatic boxes are reliable enough, but German, for example, distinguishes high quality of study and manufacturing even minor details to which Americans give less attention. "Fordovsky" boxes improve constantly, even in the course of release of the same model of the car. So "Torus" which "automatic machine" first quite often failed, has a year or two from now received quite reliable unit. The Japanese technics is rather simple, traditionally compact and abounds with electronics. But, probably, owing to national restriction of speed (100 km/h), details of boxes frequently have unimportant dynamic balancing that sometimes leads to destruction of bearings of sliding.

- What contingent of your clients?

- The diversified. Basically it is those who gets automobile "sekond - a hand" though there are also cars of members of the government, ФСК and even managements of protection of the president. Besides, our experts advise ГОН - Garage of special function concerning operation of automatic boxes.

- Tell, and whether is at ATG any independent workings out?

- We have developed and have patented automatic transmissions for all front-wheel VAZs, including cars of the "tenth" family, "Moskvicha-2141" and Izh - 2126 "Orbit". Actually "automatic" part at them is identical. But that the most valuable - our "automatic machines" are mounted instead of regular mechanical boxes without any alterations of the car. Invariable there are even drives or the driveshaft. That these workings out have gone to a series, interest of car factories and considerable means which they yet have no is necessary. But we hope that sometime and buyers of the domestic car can choose between usual "mechanics" and "automatic machine".
