Description and operation
• |
The hydraulic system consists of a valve body, an oil filter and an
oil pump.
|
• |
The oil pump is powered by the engine. ATF passes through the oil filter
and gets distributed along the oil channels.
|
• |
The oil becomes highly pressurized as it exits the oil pump and passes
through the line pressure valve before being fed to the clutch & brake
control valve, clutch, and brakes.
|
• |
TCM controls the hydraulic pressure using solenoid valves and controls
clutch and brake operations.

Valve Body. Description and operation
• |
The valve body is essential to automatic transaxle control and consists
of various valves used to control the oil feed from the oil pump. Specifically,
these valves consist of pressure regulator valves, oil redirection valves,
shift valves, and manual valves.
|
• |
The body also features electronic solenoid valves that ensure smooth
gear changes.

Valve Body. Repair procedures
•
|
Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|
•
|
When the solenoid valve Diagnostic Trouble Codes (DTC) is on,
perform the following procedure to replace it.
|
•
|
Automatic transaxle is composed of delicate components. Be careful
not to cause any damage on the component in the course of assembly
and disassembly.
|
•
|
Maintain clean condition so that foreign substance does not
get into the automatic transaxle.
|
•
|
Use a coated apron, latex gloves, and stainless tray to prevent
foreign substance from getting into the transaxle.
|
•
|
Automatic transaxle fluid (ATF) can be reused. Collect it using
a clean 10-liter beaker.
|

Even though disconnecting the battery negative terminal,
the DTCs will not be cleared. So, be sure to clear the
DTCs using the diagnostic tool.
|
|
|
4. |
Reset the automatic transaxle adaptive values using the diagnostic tool.
|
5. |
Input the oil pressure characteristics using the diagnostic tool.
(1) |
Select ‘Oil-pressure Characteristics (Solenoid Valve Replacement)’
in the S/W Management.
|
(2) |
Select the replaced solenoid valve.
|
(3) |
Check the code marked on the solenoid valve.
(※ Caution : Check the code at first before replacement)
|
(4) |
If the code is inputted 2 times correctly, the procedure is
completed.

Underdrive Brake Control Solenoid Valve (UD/B_VFS). Repair procedures
•
|
Refer to the DTC manual for the check procedure.
|
|
•
|
Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|
•
|
When the solenoid valve Diagnostic Trouble Codes (DTC) is on,
perform the following procedure to replace it.
|
•
|
Automatic transaxle is composed of delicate components. Be careful
not to cause any damage on the component in the course of assembly
and disassembly.
|
•
|
Maintain clean condition so that foreign substance does not
get into the automatic transaxle.
|
•
|
Use a coated apron, latex gloves, and stainless tray to prevent
foreign substance from getting into the transaxle.
|
•
|
Automatic transaxle fluid (ATF) can be reused. Collect it using
a clean 10-liter beaker.
|
|
