Check up level ATF (Routine maintenance see the Head).
Diagnostics of leaks ATF
The general information
The majority of leaks easily come to light at visual check. Repair usually consists in replacement of a corresponding defective epiploon or a lining. If to reveal a source of leak during external survey it is not possible, operate, as it is described more low.
First of all it is necessary to exclude probability of an error in definition of the nature of leak. It is not necessary to confuse ATF to impellent oil or a brake liquid (трансмиссионная the liquid usually has dark red colour).
For revealing of a source of leak make short (some kilometres) a trip, then park the car over the spread blank leaf of a cardboard. After pair minutes the leak source can be revealed in the wake of a liquid dripping on a cardboard.
Attentively examine a suspected site and a surface surrounding it, special attention giving to joints interfaced прокладочных surfaces. For the purpose of expansion of a corner of the review take advantage of a pocket pocket mirror.
If to reveal a leak source still it is not possible, carefully wipe a surface of a suspected site the rags moistened with solvent, then dry it.
Make one more short trip, this time often changing speed of movement, then again examine the cleaned suspected site.
After revealing of a source of leak, it is necessary to define and eliminate the reason of its development, and only then to pass to performance of a necessary recovery work. Replacement of the damaged lining will not lead to desirable result if to leave not eliminated the defect of the interfaced surface which have led to an exit of a sealant out of operation. So, the deformed flange it is necessary отрихтовать.
In below-mentioned subsections the most typical reasons of development of leaks ATF and conditions which should be executed that there were no relapses are listed.
Leaks through прокладочные surfaces
Periodically examine the pallet картера transmissions. Check presence on the places and reliability of a tightening of fixing bolts, watch, that on a cover there were no traces of mechanical damages (pallet deformation can lead to failure located in transmission клапанной assemblages).
Excessively hard tightening of fixing bolts, infringement of passableness of a ventilating line, mechanical damage of a sealing surface concern number of the possible reasons of development of leaks through the pallet картера transmissions, lining destruction, and also occurrence of cracks or порозности walls картера. If the lining of the pallet or картера transmissions is formed by a hermetic pillow, the probability of a wrong choice of type of the last is not excluded. Overflow can result in leaks чрез картера трансмиссионной a liquid, or increase of pressure ATF a pallet lining also.
Leaks through epiploons and cuffs
Excessively high level/pressure ATF, infringement of passableness of a ventilating branch pipe, mechanical damage of walls of a landing nest, damage out of operation concern number of the most typical reasons of an exit of epiploons of transmission actually an epiploon, or wrong installation of the last. The probability of damage of a pin of the shaft passed in an epiploon, or excessive люфт the last as a result of deterioration of bearings is not excluded also.
Check up a condition and correctness of landing of a sealing cuff of a directing tube measuring probeа. Periodically examine on presence of signs of leaks a surface around an arrangement приводной gear wheels of a speedometer/gauge of speed (VSS). In case of need make replacement of a sealing ring.
Leaks through defects in walls картера transmissions
The reason of development of leaks ATF formation of cracks or a time in a body картера transmissions can be, - consult at experts of car-care centre.
Check up tightness штуцерных knots of connection of hoses of cooler ATF.
Leaks through сапун and a jellied mouth
Leaks through сапун ventilation or a jellied mouth can occur owing to overflow of transmission, hit in ATF a cooling liquid, passableness infringement sapuna / a ventilating branch pipe or returnable drainage apertures.
Check of working capacity of transmission on the motionless car
During the given check engine turns in all positions of transmission, except “N” and “Р” are defined. The check purpose is the estimation of working capacity of elements of management and hydrotransformer AT. Serviceability of functioning of the engine is simultaneously checked also.
