4. Install the 2-3 accumulator piston oil seal ring (137B) onto the 2-3 accumulator piston (136B). Lubricate the oil seal ring with automatic transmission fluid.
5. Assemble the 2-3 accumulator piston pin (135B) and piston (136B).

Important: Do not mix up spring or pistons/springs. Be sure to install the correct springs in the correct bore.

6. Install the 2-3 accumulator piston springs (138, 143) and piston assembly (136B) into the accumulator housing (140).
7. Install the 1-2 accumulator piston oil seal ring (137A) onto the 1-2 accumulator piston (136A). Lubricate the oil seal ring with automatic transmission fluid.
8. Assemble the 1-2 accumulator piston pin (135A) and piston (136A).

Important: Do not mix up spring or pistons/springs. Be sure to install the correct springs in the correct bore.

9. Install the 1-2 accumulator piston springs (139, 142) and the piston assembly (136A) into the accumulator housing (140).
10. Assemble the accumulator cover spacer plate assembly (134) and the accumulator cover (132) onto the accumulator housing (140).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

11. Install seven accumulator cover bolts (131).

Tighten
Tighten the accumulator cover bolts to 12 N·m (106 lb in).

12. Assemble the lube oil pipe (126), hose (128), hose clamps (127), pipe retainer (129) and pipe with washer (130).
13. Assemble the 2-1 manual band servo and forward band servo oil pipes (124, 125) into the accumulator assembly (132-140).
14. Assemble the 2-1 manual band servo and forward band servo oil pipes (124, 125) into the 2-1 manual band servo cover (104).
15. Install the lube oil pipe assembly (126-130) into the accumulator assembly (132-140).
