Description and operation
| • |
UD clutch control solenoid valve is a Variable Force Solenoid (VFS) type.
|
| • |
When TCM supplies variable current to solenoid valve, hydraulic pressure
of 4&OD clutch is controlled directly by solenoid valve.

Repair procedures
| 2. |
Disconnect the main connector (A).
|
| 3. |
Measure the resistance between power terminal (22) and signal terminal
(28).
|
Specification : 5.3 ± 0.3 Ω
|
|
| • |
Maintain clean condition so that foreign substance does not get
into the automatic transmission.
|
| • |
Use a coated apron, latex gloves, and stainless tray to prevent
foreign substance from getting into the transmission.
|
|
| 1. |
Remove the under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover").
|
| 2. |
Remove the ATF drain plug (A), allow the fluid to drain out and then
reinstall the drain plug.
|
Tightening torque :
22.6 - 24.5 N·m (2.3 - 2.5 kgf·m, 16.6 - 18.1 lb·ft)
|
| •
|
ATF can be reused. Collect it in a clean beaker.
|
| •
|
The existing ATF drain plug O-ring must be replaced with
a new one. (Do not reuse it.)
|
|
|
| 3. |
Disconnect the main connector (A).
|
| 4. |
Remove the valve body cover.
| (1) |
Loosen the all valve body mounting bolts except for the bolts
(A) in the corner.
|
Tightening torque :
13.7 - 15.7 N·m (1.4 - 1.6 kgf·m, 10.1 - 11.6 lb·ft)
|
|
| (2) |
Loosen the two bolts (A) in the corner after supporting the valve
body cover on a jack and then remove the valve body cover by lowering
the jack slowly.
|
Be careful when removing the valve body cover because
the remaining ATF remains in the valve body cover.
|
|
|
| 5. |
Remove the valve body assembly (A) after loosening the bolts.
|
Tightening torque :
9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)
|
|
| 6. |
Remove the E-module (A) after loosening the bolts.
|
Tightening torque :
9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)
|
|
When installing, after mounting the E-module, lightly tap the
connector part (A) to insert the connector certainly and then tighten
the bolts.
|
|
| 7. |
Remove the solenoid valve support bracket (A).
|
Tightening torque :
11.8 - 13.7 N·m (1.2 - 1.4 kgf·m, 8.7 - 10.1 lb·ft)
|
|
| 8. |
Remove the pin (A).
|
| 9. |
Remove the UD clutch control solenoid valve (A).
|
| 1. |
Install in the reverse order of removal.
| •
|
Check the code (oil pressure characteristics value) at
the first before installing the solenoid valve.
|
| •
|
Check if the pipe (A) is inserted on the marked area
before mounting the valve body assembly.
|
|
|
| 2. |
Perform the procedures below after installing.
| (1) |
Refill the automatic transmission with fluid.
(Refer to Hydraulic System - "Fluid")
|
| (2) |
Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting
the battery negative terminal will not clear the DTCs. Clear DTCs
using the KDS at all times.
|
| (3) |
Reset the automatic transmission adaptive values using the KDS.
|
| (4) |
Perform the oil pressure characteristics input procedure using
the KDS.
(Refer to Hydraulic System - "Oil pressure characteristics input")
|
| (5) |
Perform the TCM adaptive values learning procedure.
(Refer to Automatic Transmission Control System - "Repair procedures")
|
| (6) |
After installing, check for leakage of fluid from hose connection
during engine start.
