On all models considered in the real Management, both rear-wheel (4х2), and all-wheel drive (4х4), at the corresponding complete set it is established completely synchronized (including a reverse gear) a 5-step manual box of gear shifting (RKPP) of a design Getrag providing possibility of inclusion of five lobbies and one back transfers.

In a box four shesterenchaty shaft are used: primary (entrance), secondary (main), counterdriving and intermediate reverse gear. The forward end of a secondary shaft is entered into the needle bearing filled in a back pin of primary shaft. At a choice of the 4th transfer the nave of the sliding coupling of the synchronizer provides direct mechanical gearing of primary and secondary shaft with the transfer relation 1:1. Thus, five gelikoidalny gear wheels of primary shaft enter into continuous reduktorny gearing with a counterpower shaft only: the first, the second, thirds, fifth and back transfers.

Five gear wheels of a counterpower shaft are an integral part of the last and rotate together with it, perceiving a torque from primary shaft. Entered into continuous gearing with a counterpower shaft of a gear wheel of a secondary shaft are planted on needle bearings that provides independence of their rotation till a choice of the corresponding transfer. The intermediate gear wheel of a reverse gear is also planted on the bearing and has the fixed situation on the to a shaft.

Established on assembly of the central console in car salon the lever of gear shifting is connected to an operating rod. The rod is passed in the top part of a face surface of back section of a case of RKPP and can be entered into gearing with one of three equipped rods of switching located in a case forks. Forks of switching of each of internal rods, in turn, are entered into gearing with sliding couplings of the corresponding synchronizers. The choice of transfer is carried out by means of shift of the demanded coupling by the fork in the direction of a gear wheel of the corresponding transfer of a secondary shaft, thus the internal gear surface of the coupling carries out a role of the connecting link jointing a gear wheel from planted on a shlitsa of a shaft by a gear nave of the synchronizer.

All components of a transmission are placed in a two-section aluminum case of a vertical joint into which forward section the lever of switching off of coupling and the sensor of provision of a cranked shaft (CKP) are entered, in back section the sensor switch of fires of a backing is located on all models. To a face part of back section of a case of RKPP of rear-wheel models приболчен the lengthening case, on models 4´ 4 - a case of a transfer case on which the sensor of speed of movement of the car (VSS) fastens.

In view of complexity of a design of RKPP, absence on free sale of necessary replaceable internal components and need of use of the special equipment, originators of the real Management do not recommend to owners of cars to carry out major maintenance of a transmission independently. RKPP repair in the conditions of a workshop of car-care center is rather expensive operation, in a type of that, it is meaningful to consider alternative options of replacement of the failed block new or restored. Any useful information on repair and replacement of transmission can be received on the firm HUNDRED companies KIA.

Regardless of the chosen way of elimination of problems (repair or replacement), independent dismantle of a box from the car will allow to reduce material inputs essentially.
