Lubrication System Construction

WARNING: This page is about a different car, the 2008 Mazda RX-8, 2007 Mazda RX-8, 2006 Mazda RX-8, 2005 Mazda RX-8, and 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

In the conventional system, the rear section is lubricated by ATF returning from the ATF oil cooler. In the new system, all parts are lubricated directly from the control valve.
With this construction, the system is unaffected by the ATF oil cooler, and thus a steady amount of lubricant is supplied.

A passage located in the rear of the extension housing supplies a steady amount of lubricant exclusively to the bushing.
