Due to the complexity of the design of clutches and electronic and hydraulic systems, as well as the need to use special tools and the application of specific control methods when repairing an automatic transmission, diagnosis and repair should be carried out at a proprietary or suitably equipped service and repair station. This chapter is limited to a general description of status checking procedures. routine maintenance and adjustment (replacing the gear shift lever, replacing and adjusting the shift mechanism cable, etc.). More complex repair procedures should be performed by qualified service technicians. Regardless of your decision regarding repair or replacement of the transmission, you can save some money by performing the transmission removal and installation procedures yourself, which are also described in this chapter.
