Diagnostics of leakages of ATF
General informationThe majority of leaks easily come to light at visual check. Repair usually consists in replacement of the corresponding defective epiploon or laying. If it is not possible to reveal a leak source during external survey, act as it is described below.
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).
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 a couple of minutes the source of leak can be revealed in the wake of the liquid dripping on a cardboard.
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.
If it is not possible to reveal a leak source still, carefully wipe a surface of the suspected site the rags moistened with solvent, then dry it.
Make one more short trip, this time often changing movement speed, then again examine the cleaned suspected site.
After identification 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 necessary recovery work. Replacement of the damaged laying will not lead to desirable result if to leave not eliminated the defect of the interfaced surface which led to a laying exit out of operation. So, the deformed flange needs to be aligned.
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. Remark: Part cannot be executed from the listed requirements without use of the special equipment. In this case the car should be driven away on car repair shop.
Leaks through pro-masonry surfacesPeriodically 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.
Through a cover 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.
Leaks through epiploons and cuffs
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.
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 make replacement of a sealing ring.
Leaks through defects in transmission case wallsFormation of cracks or time in a transmission case body can be the reason of development of leakages of ATF. Consult with specialists of car service.
Check tightness of nipple knots of connection of hoses of a cooler of ATF.
Leaks through sapun and a jellied mouthLeaks through sapun 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.
