8.1. 4-step automatic transmission

4-step AT enters into a standard complete set of Infiniti QX4 cars with electronic control of the RE4R01A type

In view of complexity of a design of AT, absence on free sale of 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 transmission 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, it is more reasonable and simpler to replace transmission, than to waste time and funds for restoration of the failed assembly. Regardless of the chosen way of introduction of refused AT in action, independent performance of procedures of its removal and installation will help to cut down substantially expenses (before make sure that transmission really needs regenerative repair).

The detailed description of a design and principles of functioning of transmission is provided in the ARUS No. 179 series (ISBN 5-89744-069-7) Management.
