Removal Procedure
- Remove
the transaxle case side cover. Refer to
Control Valve Body Cover Replacement
.
- Remove the oil pump bolts and the oil pump assembly.
- Remove the oil pump shaft.
- Disconnect the wire harness connectors from
the following components:
• | Pressure control solenoid |
• | 1-2, 2-3 shift solenoids |
- Remove the TFP switch assembly bolts and
remove the switch assembly from the control valve body. The 7 TFP switch O-rings
are reusable if not damaged and should remain with the pressure switch assembly.
- Remove the remaining control valve body
bolts (9, 12, 16) and remove the control valve body assembly (18).
- Remove the spacer plate support bolts (20)
and remove the spacer plate support (21).
Important: Checkballs may fall out of the channel plate
assembly. Retain the checkballs with petroleum jelly.
- Remove the spacer plate (90) with the spacer plate filter attached.
- Remove and discard the spacer plate assembly (90).
Disassembly/Assembly Procedure
For step by step instructions on how to disassemble/assemble the control valve
body, refer to
Control Valve Body Disassemble
and
Control Valve Body Assemble
.
Installation Procedure
- Make sure the checkballs (1-7) are
in the proper locations on the channel plate. Retain the checkballs with petroleum
jelly.
- Install a new spacer plate assembly (90)
onto the channel plate.
Notice: Refer to Fastener Notice in the Preface section.
- Hand start the spacer plate support bolts (20) and install the spacer
plate support (21).
Tighten
Tighten the spacer plate support bolts to 14 N·m
(10 lb ft).
- Install a new control valve body to the
spacer plate assembly (90).
- Install the control valve body assembly onto the gasket. Hand start the
control valve body assembly bolts (9, 12, 16) to hold the valve
body in place.
- Inspect
the TFP switch assembly (2) in order to verify the condition and the correct
location of the pressure switch O-rings. If necessary, replace the TFP switch assembly
O-rings.
- Install the TFP switch assembly onto the control valve body assembly.
Install the remaining control valve body bolts.
- Hand start the bolts.
Tighten
Tighten the control valve body bolts to 12 N·m
(9 lb ft).
- Connect the transaxle wiring harness to the following components:
• | Pressure control solenoid (red connector) |
| Important: The 1-2 shift solenoid wires
are red and green. The 2-3 shift solenoid wires are red and yellow.
|
- Install
the oil pump shaft into the control valve body assembly.
Important: If necessary, rotate the oil pump shaft while
installing the oil pump assembly in order to engage the shaft splines to the splines
on the oil pump rotor.
- Install the oil pump assembly onto the oil pump shaft and the control valve
body. Hand start and install the oil pump assembly bolts.
Tighten
Tighten the oil pump bolts to 12 N·m
(9 lb ft).
- Install the transaxle case side cover. Refer to
Control Valve Body Cover Replacement
.
- Start the engine, warm up the transaxle, and check for leaks.
- Inspect for proper fluid level. Refer to
Transmission Fluid Check
.
Important: It is recommended that transmission adaptive
pressure (TAP) information be reset.
Resetting the TAP values using a
scan tool will erase all learned values in all cells. As a result, the ECM, PCM or
TCM will need to relearn TAP values. Transmission performance may be affected as new
TAP values are learned.
- Reset the TAP values. Refer to
Transmission Adaptive Functions
.
