Repair procedures: Disassembly
CAUTION:
- Automatic transaxles consist of delicate parts. Be careful not to damage them in disassembly and assembly.
- Spread a rubber mat on a workbench and keep it clean.
- Do not use cotton or muslin fiber. Use nylon fabric or paper towel.
- Cleanse the disassembled components. Clean metal parts with a general cleaning agent or dry them with a blower.
- Clean clutch discs, thrust plates made of resin, and rubber parts with automatic transaxle fluid and keep them dust free.
- If transaxle body has been damaged, disassemble and clean cooler system.
- Remove the torque converter.
- Measure the input shaft (A) end play using a dial gauge.
Input shaft end play:
0.7~1.45mm (0.0276~0.0571 inch)
- Remove the fluid level gauge.
- Remove the input (A) and the output speed sensor (B).
- Remove the eyebolt, the gasket, and the fluid cooler feed tube.

- Using the SST (09215-3C000), remove the valve body cover (A).
- Remove the manual control shaft detent spring (A).
- Remove the VFS (variable force solenoid) reservoir (A) and tube assembly (B).
- Disconnect the harness connector from the valve body.
- Remove the valve body mounting bolts (26EA), except those bolts (A) marked on illustration. (6X45-1EA, 6X75-1EA, 6X106-10EA, 6X38-9EA, 6X20-2EA, 6X25-2EA, 6X30-1EA)
- Remove the valve body (A) and the steel balls (2EA).CAUTION: Be careful not to lose the steel balls.
- Remove the solenoid valve harness snap ring (A).
- Remove the solenoid valve harness.
- Remove the strainer (A).
- Remove the 2ND brake retainer oil seal (A).CAUTION: If the 2ND brake retainer oil seal is not removed, it may be damaged when removing and installing the second brake piston.
- Remove each accumulator piston and spring.BRAKE PISTON NAME REFERENCE CHART
