8.1. 4-step automatic transmission
Into a standard complete set of cars Infiniti QX4 enters 4-step АТ with electronic control of type RE4R01A
In view of complexity of design АТ, absence on free sale of replaceable internal components, and necessity of use of the special equipment, composers of the present Management do not recommend to owners of cars to carry out transmission major repairs by own forces. In the present Chapter procedures of diagnostics of the general refusals of transmission, its routine maintenance, adjustments, removals and installations are considered only.
Sometimes, in case of serious breakage to replace transmission more reasonably and easier, than to waste time and means for restoration of the failed assemblage. Without dependence from the chosen way of introduction refused АТ in action, independent performance of procedures of its removal and installation expenses (before make sure that transmission really requires regenerative repair) will help to cut down substantially.
The detailed description of a design and principles of functioning of transmission is resulted in the Management of series АРУС № 179 (ISBN 5-89744-069-7).
