AUTOMATIC TRANSMISSION SHIFT MECHANISM OUTLINE
EHU051446010101
•
The construction and operation of the automatic transmission shift mechanism system is essentially carried
over from that of the 2005MY RX-8, except for the following.
—
The TCM terminal has been changed for the SJ6A-EL automatic transmission model only.

STEERING SHIFT SWITCH CONSTRUCTION/OPERATION
EHU051446102101
Construction
•
There is one pair of up and down switches on both the left and right sides of the steering wheel.
•
The circuits of the down switches are built into the audio control switch and cruise control switch. (For vehicles
without cruise control, there is only a down switch.)
Operation
Sending of up/down-shift request signals
•
The TCM detects an up/down-shift request signal according to the voltage applied to terminal 1W
*1
, 2AF
*2
.
•
When the up or down switch is operated, the resistor built into the down switch changes the voltage applied to
TCM terminal 1W
*1
, 2AF
*2
.
•
The TCM controls upshifting or downshifting based on this change in voltage.
