Problem diagnostics AT/CVT – the general information

Primary checks

PERFORMANCE ORDER

1. Warm up transmission to normal working temperature during a short trip. 2. Check ATF level (see. Head Routine maintenance):    a) If liquid has not enough, make the corresponding adjustment, having added necessary quantity of fresh ATF. Be convinced of correctness of the carried-out adjustment according to indications measuring щупа, then check transmission on existence of signs of external leaks (see below);    b) If level is too high, merge surplus of ATF, then check it on existence of traces of the cooling liquid, testifying violation of tightness of internal partitions of the radiator separating its heat exchanger from lateral tanks with ATF (see. Head of System of cooling and heating);    c) If ATF foams, empty transmission and fill it with fresh liquid, – merged check on existence of traces of cooling liquid. 3. Check installation of turns of idling of the engine. If the engine not as it should be, it is not necessary to start performance of primary checks of transmission until the corresponding corrections will be made. 4. Check freedom of moving of a driving cable of management of a butterfly valve in the kick-down mode (Integra model), in case of need make the corresponding adjustment (see. Adjustment of seats). The cable can functionaries ать it is normal on the cold muffled engine that is not a guarantee of serviceability of its action on the working and heated-up unit to normal working temperature. Make cable check at various conditions of the engine. 5. Check draft of a cable of gear shifting (see. The equipment and governing bodies in salon), make sure of correctness of adjustment and freedom of its moving.

Diagnostics of leakages of ATF

PERFORMANCE ORDER

1. The majority of leaks easily are defined at visual check. Repair usually consists in replacement of a defective epiploon or laying. If to reveal a source to leak during visual survey it is not possible, act, as it is described below. 2. First of all it is necessary to exclude probability of a mistake in definition of the nature of leak. It is not necessary to confuse ATF to impellent oil or brake liquid (transmission liquid usually has dark red color). 3. For identification of a source of leak make short (some kilometers) a trip, then park the car over the outspread blank sheet of a cardboard. Later few minutes the source of leak can be revealed in the wake of liquid dripping on a cardboard. 4. Attentively examine a suspected site and a surface surrounding it, special attention giving to a joint of interfaced prokladochny surfaces. For the purpose of expansion of a corner of the review use a pocket pocket mirror. 5. 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. 6. Make one more short trip, this time often changing speed of movement, then again examine the cleaned suspected site. 7. After identification of a source of leak, it is necessary to define and eliminate the reason of its development, only then to pass to performance of necessary recovery operations. Replacement of laying will not lead to desirable result if to leave not eliminated the defect of the interfaced surface which has led to its exit out of operation. 8. In below-mentioned subsections the most typical reasons of development of leakages of ATF and a condition which should be executed that there was no recurrence are listed. Part from the listed conditions cannot be observed without use of the special equipment. In this case the car should be driven away on car repair shop.

Prokladochnye of a surface

PERFORMANCE ORDER

1. Periodically examine a cover on the right side of a transmission case. Check existence on the places and reliability of a tightening of fixing bolts, watch, that on a cover there were no traces of mechanical damages. 2. Excessively hard tightening of fixing bolts, damage of a sealing surface of a case of transmission, laying destruction, and also emergence of cracks belong to number of the possible reasons of development of leaks through covers or a poroznost of walls of a case. If laying of a cover or a case of transmission is formed by a hermetic pillow, the probability of the wrong choice of type of the last is not excluded.

Epiploons and cuffs

PERFORMANCE ORDER

1. Excessively high level of ATF, violation of passableness out of operation belong to number of the most typical reasons of an exit of epiploons of transmission ventilating сапуна, mechanical damage of walls of a landing nest, damage actually an epiploon, or the 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 wear of bearings is not excluded also. 2. Check a condition and correctness of landing of a sealing cuff of a directing tube measuring щупа. Periodically examine on existence of signs of leaks a surface around an arrangement of a driving gear wheel of a speedometer or the sensor of speed (VSS). In case of need make replacement of a sealing ring.

Transmission case

PERFORMANCE ORDER

1. Formation of cracks or a time in a body of a case of transmission can be the reason of development of leakages of ATF. Consult with specialists of car-care center. 2. Check tightness of shtutserny knots of connection of hoses of a cooler of ATF.

Sapun and jellied mouth

Leaks through сапун or a jellied mouth can occur owing to excessive filling of transmission, hit in ATF of cooling liquid, passableness violation сапуна or returnable openings.
