Failure diagnostics of AT/CVT – the general information

Refusals of AT and CVT most often happen for one of the following five reasons: decrease in efficiency of return of the engine, violation of adjustments, malfunctions of hydraulics, mechanical damages, or failures of the onboard processor or its alarm chain. Failure diagnostics always has to begin with the simplest checks: estimate the level and a condition of ATF (see the Head Routine maintenance), check adjustment of cables of management of gear shifting and the provision of a butterfly valve in the kick-down mode. Further, carry out trial runs of the car for the purpose of definition of efficiency of the made corrections. If it was not succeeded to fix a problem, it is necessary to drive away the car on car repair shop for more detailed diagnostics with use of the special equipment. The description of some of symptoms of refusals of AT/CVT is provided in Diagnostics of malfunctions of knots and systems of the car.

Primary checks

 PERFORMANCE ORDER

1. Warm up transmission up to the normal working temperature during a short trip.
2. Check the ATF level (see the Head Routine maintenance):
   a) If liquid is obviously not enough, make the corresponding adjustment, having added necessary quantity ATF is fresher. Be convinced of correctness of the carried-out adjustment according to indications of the measuring probe, then check transmission for existence of signs of external leaks (see below);
   b) If level is too high, merge surplus of ATF, then check it for existence of traces of cooling liquid, the testifying violation of tightness of the internal partitions of a radiator separating its heat exchanger from side tanks with ATF (see the Head of the Cooling system and heating);
   c) If ATF foams, empty transmission and fill it with fresh liquid, – merged check for 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 are made.


4. Check freedom of movement 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

to at normally on the cold killed engine that is not a guarantee of serviceability of its action on the unit working and warmed up up to the normal working temperature. Make check of a cable 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 movement.

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 leak does not manage to reveal a source during visual survey, 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 motive oil or brake fluid (transmission liquid usually has dark red color).
3. For identification of a source of leak make short (several kilometers) a trip, then park the car over the outspread blank sheet of a cardboard. Later a couple of minutes the source of leak can be revealed in the wake of the liquid dripping on a cardboard.
4. Attentively examine the suspected site and the surface surrounding it, paying special attention a joint of the interfaced pro-masonry surfaces. For the purpose of expansion of a viewing angle use a pocket mirror.
5. If it is not possible to reveal a leak source still, carefully wipe the surface of the suspected site with the rags moistened with solvent, then dry it.
6. Make one more short trip, this time often changing the speed of the movement, then again examine the cleaned suspected site.
7. After identification of a source of leak, it is necessary to define and remove the cause of its development, only then to pass to performance of necessary recovery work. Replacement of laying will not result in desirable result if to leave not eliminated the defect of the interfaced surface which led to its exit out of operation.
8. In the following subsections the most typical reasons of development of leakages of ATF and a condition which have to 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.

Pro-masonry surfaces

 PERFORMANCE ORDER

1. Periodically examine a cover on the right side of a transmission case. Check existence on the places and reliability of tightening of fixing bolts, you watch that on a cover traces of mechanical damages did not appear.
2. Through covers excessively hard tightening of fixing bolts, damage of a sealing surface of a case of transmission, laying destruction, and also emergence of cracks or porosity of walls of a case are among the possible reasons of development of leaks. If laying of a cover or case of transmission is formed by a sealant pillow, the probability of the wrong choice of type of the last is not excluded.

Epiploons and cuffs

 PERFORMANCE ORDER

1. The most typical reasons of an exit of epiploons of transmission excessively high ATF level, violation of passability of a ventilating sapun, mechanical damage of walls of a landing nest, damage actually out of operation are among an epiploon, or the wrong installation of the last. Also the probability of damage of a pin of the shaft passed throughout an epiploon, or an excessive side play of the last as a result of wear of bearings is not excluded.
2. Check a state and correctness of landing of a sealing cuff of the directing tube of the measuring probe. 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 the speed (VSS). In case of need you make replacement of a sealing ring.

Transmission case

 PERFORMANCE ORDER

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

Sapun and jellied mouth

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