A/T CONTROL SYSTEM : Protection Control
INFOID:0000000009267846
The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM is equipped with the following protection control.
REVERSE INHIBIT CONTROL
Intercepts the torque transmission and shifts to the neutral status if the selector lever is shifted to “R” position
while the vehicle moves forward at the vehicle speed 10 km/h (7 MPH) or more.
TCM HIGH TEMPERATURE PROTECTION CONTROL
When the ATF becomes hot, the shifting pattern is changed for preventing fluid temperature rise.
TORQUE-DOWN CONTROL WHEN CONTINUOUS STALL OCCURS IN D POSITION
If the accelerator pedal is continually depressed for a certain length of time when the selector lever is in the “D”
position and the vehicle is parked, the engine output is limited for protecting the transaxle.
O/D PROHIBIT CONTROL AT LOW TEMPERATURES
When the ATF temperature is low immediately after engine start, shifting to 4GR is prohibited for protecting the
transaxle and allowing the exhaust gas characteristics to warm up quickly.

Vehicle behavior
Vehicle condition
Operation detection conditions
• Vehicle speed: 10 km/h (7 MPH) or more (when driving forward)
• Selector lever is shifted to “R” position.
Control when activated
Neutral
Recovery condition
• Vehicle speed: 7 km/h (4 MPH) or less
and
• Engine speed: 2,800 rpm or less
Vehicle behavior
• The torque transmission cannot be performed
• There is a shock just before a vehicle stop
Operation detection conditions
ATF temp.: 125
°C (257°F) or more
Control when activated
Change the shift pattern so that higher upshift may be achieved.
Recovery condition
• ATF temp.: 119
°C (246°F) or less
Vehicle behavior
Upshifts at a higher vehicle speed than usual.
Operation detection conditions
The following conditions continue for 20 seconds or more
• Selector lever is in the “D” position or “R” position and the vehicle is stopped
and
• Engine speed: 2,300 – 2,850 rpm
Control when activated
Limits engine output
Recovery condition
• Selector lever is shifted to a position other than “D” or “R”
or
• The accelerator pedal is released
Vehicle behavior
• Decreased starting performance
• Engine speed hunching when the accelerator pedal is depressed

LINE PRESSURE CONTROL

INFOID:0000000009267847
LINE PRESSURE CONTROL : System Description
INFOID:0000000009267848
• When an engine and A/T integrated control signal (engine torque) equivalent to the engine drive force is
transmitted from the ECM to the TCM, the TCM controls the line pressure solenoid valve.
This line pressure solenoid controls the pressure regulator valve as the signal pressure and adjusts the pres-
sure of the operating oil discharged from the oil pump to the line pressure most appropriate to the driving
state.
• The TCM has stored in memory a number of patterns for the optimum line pressure characteristic for the
driving state.
• In order to obtain the most appropriate line pressure characteristic to meet the current driving state, the TCM
controls the line pressure solenoid current value and thus controls the line pressure.
Normal Control
Operation detection conditions
• ATF temp.: 0
°C (32°F) or less
or
• ATF temp.: less than 40
°C (104°F) (when IGN is ON)
• Vehicle speed: 65 km/h (40 MPH) or less
• 3GR
Control when activated
4GR prohibited
Recovery condition
Less than 130 seconds following IGN ON
• ATF temp.: 40
°C (104°F) or more
or
• Vehicle speed: 65 km/h (40 MPH) or higher
After 130 seconds following IGN ON
• ATF temp.: 0
°C (32°F) or more
Vehicle behavior
Shifts up only as far as 3GR.

Each clutch is adjusted to the necessary pressure to match the
engine drive force.
Back-up Control (Engine Brake)
When the select operation is performed during driving and the A/T is
shifted down, the line pressure is set according to the vehicle speed.
During Shift Change
The necessary and adequate line pressure for shift change is set.
For this reason, line pressure pattern setting corresponds to engine
torque and gearshift selection. Also, line pressure characteristic cor-
responds to engine speed, during engine brake operation.
