Nissan Rogue. Instruction — part 1167
TM-40
< SYSTEM DESCRIPTION >
[CVT: RE0F10D]
SYSTEM
DESCRIPTION
Based on accelerator pedal angle, engine speed, primary pulley speed, and the input speed, the optimum
operating pressure is set to reduce impact of a selector lever operation while shifting from “N” (“P”) to “D” (“R”)
position.
LOCK-UP CONTROL
LOCK-UP CONTROL : System Description
INFOID:0000000011279277
SYSTEM DIAGRAM
DESCRIPTION
• Controls for improvement of the transmission efficiency by engaging the torque converter clutch in the
torque converter and eliminating slip of the converter. Achieves comfortable driving with slip control of the
torque converter clutch.
• The oil pressure feed circuit for the torque converter clutch piston chamber is connected to the torque con-
verter clutch control valve. The torque converter clutch control valve is switched by the torque converter
clutch solenoid valve with the signal from TCM. This controls the oil pressure circuit, which is supplied to the
torque converter clutch piston chamber, to the release side or engagement side.
• If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is
prohibited.
Lock-up engagement
In lock-up engagement, the torque converter clutch solenoid valve makes the torque converter clutch control
valve locked up to generate the lock-up apply pressure. This pushes the torque converter clutch piston for
engagement.
Lock-up release condition
In lock-up release, the torque converter clutch solenoid valve makes the torque converter clutch control valve
non-locked up to drain the lock-up apply pressure. This does not engage the torque converter clutch piston.

SPORT MODE CONTROL : System Description
INFOID:0000000011279278
SYSTEM DIAGRAM
DESCRIPTION
• For a sporty driving on winding roads, establishing sport mode allows the driver to perform a sporty driving
different from normal driving performed in D position.
• If overdrive control switch is operated during SPORT mode ON condition, overdrive control operation will
take priority.
Sport Mode Function
High Gear Ratio Limit
• Engine speed is kept higher than at D position driving, which helps to operate a “sporty” driving.

SYSTEM
Step Shift
• Pressing down the accelerator pedal allows to drive the vehicle
with a feeling of A/T-like gear shifting.
Braking Down Shift
• At a moderate braking operation before corner etc., the engine speed increases according to the decelera-
tion and the transmission shifts down automatically, in order to optimize the response at reacceleration while
providing an adequate engine braking.
Acceleration Off Ratio Hold
• When the vehicle is decelerated by quickly releasing the foot from accelerator pedal, transmission does not
shift up automatically to keep a constant gear ratio, holding the high engine speed.
When the vehicle is decelerated (by accelerator pedal OFF) in upper area of double line in below chart, the
engine speed shows a characteristic like “A”.
On the other hand, when the vehicle is decelerated (by accelerator pedal OFF) in lower area of double line in
below chart, the engine speed shows a characteristic like “B”.

Fail-Safe
If a malfunction occurs in CVT system during SPORT mode ON, SPORT mode indicator extinguishes and the
vehicle returns to standard D position driving.
ECO MODE SYSTEM
ECO MODE SYSTEM : System Description
INFOID:0000000011545133
• Driving mode that selects the shift schedule with priority on fuel economy which gives low engine revolution.
• For details on ECO mode control, refer to
DMS-23, "ECO MODE CONTROL : System Description"
FAIL-SAFE
If a malfunction occurs in the system of CVT during ECO mode, the ECO mode indicator lamp turns OFF and
the control switches to the normal mode control.
