8. Remove the 8 bolts, 5 stud bolts and the main control cover.
NOTE:Note the location of the stud bolts for assembly.
9. Disconnect the TR sensor electrical connector.
10. Disconnect the OSS sensor electrical connector.
11. Remove the main control-to-main control cover grommet.
12. Remove the nut, 22 bolts and the main control.
CAUTION:The main control should be handled with care, damage to the main control may occur.
NOTE:Note the location of the different length bolts for assembly.
13. Remove the main control-to-transaxle separator plate.
14. Remove the bolt and the OSS sensor.
Installation
1. Install the OSS sensor and the bolt.
- Tighten to 10 Nm {1.0 kgf-m, 89 in-lbf}.
2. Position the OSS and TR sensor wiring harnesses aside and install the main control-to-transaxle separator plate.
NOTE:If cleaning the main control assembly or inspecting the valves, see Main Control Valve Body Assembly Disassembly/Assembly.
3. Install the main control.
NOTE:Make sure that the manual lever pin (part of the TR sensor) is correctly installed in the manual valve.
4. Install the main control, the nut and 22 bolts. Tighten in a crisscross pattern.
- Tighten to 10 Nm {1.0 kgf-m, 89 in-lbf}.
CAUTION:Make sure not to pinch the OSS or TR sensor wiring harnesses when installing the main control.
NOTE:Install the different length bolts in the locations noted during disassembly.
5. Route the OSS sensor wiring harness and connect the electrical connector.
6. Connect the TR sensor electrical connector.
7. Install the main control-to-main control cover grommet.
8. Clean the main control cover sealing surface and inspect for damage.
9. Apply silicone to the main control sealing surface of the transaxle case.
10. Position the main control cover in place.
11. Install the main control cover bolts and stud bolts. Tighten in a crisscross pattern.
- Tighten to 12 Nm {1.2 kgf-m, 106 in-lbf}.
CAUTION:Inspect the main control-to-main control cover grommet to make sure that the seal is on the inside of the main control cover or a transaxle fluid leak will occur.
NOTE:Install the stud bolts in the locations noted during disassembly.
12. Position the transaxle fluid cooler tube bracket and transaxle fluid cooler tube assembly in place and install the 2 nuts.
