Automatic Transmission Shift Mechanism; Key Interlock System - Mazda RX-8 2004 Service Highlights

AUTOMATIC TRANSMISSION SHIFT MECHANISM

KEY INTERLOCK SYSTEM OPERATION
Positions other than P position (Key interlock is operating)
• When the selector lever is in a position or range
other than P position, the cable end is set at the
key-locked position. When the engine is switched
off and an attempt is made to turn the ignition
switch to the LOCK position, turning of the cam is
restricted by the slider because the cable end
pushes the slider to the cam side, and the ignition
switch cannot be turned to LOCK.
P Position (Key interlock is not operating)
• When the selector lever is in P position, the cable
end is at the key-unlocked position, and because
the slider does not restrict movement of the cam,
the ignition switch can be turned to LOCK.

SHIFT LOCK SYSTEM OUTLINE
• To make operation smoother and to simplify internal construction, the shift lock system directly determines
movement of the slider block with the slider pin.
• The shift lock unit consists of the interlock cable, interlock cam, and lock unit.

SHIFT-LOCK SYSTEM OPERATION
The selector lever can be shifted from P position only when the following conditions are satisfied.
• The brake pedal is depressed.
1. When the brake pedal is not depressed, the slider
pin is pressed into the position shown below by
the brake pedal. Thus the slider block is inhibited
from moving in direction A via the cam. In this
condition, the interlock cable and interlock cam
are locked, and the guide pin on the shift lever
does not move out of the position. Thus the select
lever cannot be shifted to other than P position.
2. When the brake pedal is depressed, the slider pin
moves freely in direction B. The slider block also
starts to move freely. The interlock cable and
interlock cam are not locked, thus shifting out of P
position becomes possible.
