Remove the solenoid body filter assembly by pulling it straight up from the alignment tabs. Discard the filter.
24. Remove the 10 bolts, the TR sensor detent spring and the main control valve body.
25. Using a suitable tool, remove and discard the TR sensor locking pin.
26. NOTE: TR sensor removed for clarity.
Make sure that the park pawl actuator rod does not become disengaged from the park pawl and the abutment by keeping the end of the park pawl actuator rod behind the machined valve body mating surface of the transaxle case. If the park pawl actuator rod becomes disengaged from the park pawl and the abutment, transaxle removal and disassembly is required to reinstall the actuator rod.
27. CAUTION: Make sure that the park pawl actuator rod does not become disengaged from the park pawl and the abutment or transaxle removal and disassembly is required to reinstall the actuator rod.
Remove the TR sensor.
1 Slide the TR sensor down until the manual shaft is out of the transaxle case.
2 Rotate the TR sensor detent plate counterclockwise, as viewed from below until the plate rests against the transaxle case, remove the park pawl actuating rod from the TR sensor and remove the TR sensor.
Installation
1. Install the TR sensor.
1 Position the park pawl actuating rod in the TR sensor.
2 Install the TR sensor in the transaxle case.
2. Using the special tool, install a new TR sensor locking pin.
3. NOTE: Make sure that the manual lever pin (part of the TR sensor) is correctly installed in the manual valve.
Position the TSS, OSS and TR sensor wiring harnesses aside and install the main control valve body, the TR sensor detent spring and the 10 bolts. Tighten the bolts in the sequence shown.
^ Tighten to 12 Nm (9 ft. lbs).
4. CAUTION: Do not handle the solenoid body in the leadframe area or by the screens of the solenoid body filter or damage to the solenoid body can occur.
CAUTION: Use care not to break the alignment tabs when installing the solenoid body filter. Damage to the transaxle will occur if the solenoid body is not correctly aligned.
CAUTION: Make sure that the filter passage areas are clean of foreign material before installing the filter. Damage to the transaxle will occur if the filter passages are not clean.
Install a new solenoid body filter assembly by pushing it straight down on to the alignment tabs.
5. CAUTION: Make sure not to pinch the TSS, OSS or TR sensor wiring harnesses when installing the solenoid body. Damage to the wiring harness will occur.
NOTE: Install the different length bolts in the locations noted during disassembly.
Install the solenoid body and the 11 bolts.
1 42 mm (1.65 inch) bolt
