8.1.11. Major maintenance of AT

Originators of the real Management do not recommend to owners of cars to undertake performance of major maintenance of AT independently. During performance of procedures of dismantling and assembly of transmission of transfers it is necessary to remove, and then to establish into place a set of small components. It is necessary to make mass of the most exact measurements and, by selection of adjusting washers, rings and remote plugs, accurately to expose a set of gaps. In view of all aforesaid, it will be more reasonable to charge performance of major maintenance of AT to specialists of car-care center. Let's notice that in many cases there is a possibility on an exchange basis to get the restored block that often there is cheaper, than a carrying out difficult repair.
