- Using SST, fully tap the bearing into the transmission case.
SST 09316-60011 (09316-00011, 09316-00021)
- Using needle-nose pliers, install the snap ring.
- Using SST, fully tap the bearing into the transmission case.
- INSTALL REAR AUTOMATIC TRANSMISSION OIL SEAL
- Coat the lip of a new oil seal with MP grease.
- Using SST and a hammer, tap the oil seal into the transmission case.
SST 09214-76011
Standard oil seal depth:
3.3 to 3.7 mm (0.130 to 0.146 in.)
- INSTALL BRAKE PLATE STOPPER SPRING
- Install the 2 brake plate stopper springs.
- INSTALL NO. 2 BRAKE PISTON
- Coat 3 new O-rings with ATF, and install them to the No. 2 brake piston.
- Install the No. 2 brake piston to the transmission case.
HINT:
Make sure that the parking hole of the No. 2 brake piston is on the bottom side by engaging the 2 brake piston protrusions to the transmission case spline grooves. (One groove is 3 places clockwise from the top, and the other is 2 places clockwise from the bottom as shown in the illustration).
- Install the No. 2 brake piston return spring to the transmission case.
- Set SST on the No. 2 brake piston return spring, tighten SST and compress the return spring.
SST 09380-50010
- Using SST, install the snap ring.
SST 09350-30020 (09350-07070)
- SELECT NO. 2 BRAKE FLANGE
- Measure length A (from the tip of the No. 2 brake piston to the step in the transmission case) in the illustration.*1
Standard length:
14.77 to 15.37 mm (0.5815 to 0.6051 in.)
- Assemble the 4 No. 2 brake discs, 3 No. 2 brake plates, and No. 2 brake flange as shown in the illustration. Then with a weight of 500 g (17.64 oz) or less placed on the flange, measure length B.*2
Standard:
14.11 to 14.69 mm (0.5555 to 0.5783 in.)
- Choose a No. 2 brake flange from the table so that the value of measured length A minus length B (from steps *1 and *2) will be 0.52 to 0.82 mm (0.0204 to 0.0323 in.).
Flange thickness

- Measure length A (from the tip of the No. 2 brake piston to the step in the transmission case) in the illustration.*1
- INSTALL DIRECT CLUTCH PISTON
- Coat a new O-ring with ATF, and install it to the direct clutch drum sub-assembly.
- Coat a new O-ring with ATF, and install it to the direct clutch piston.
- Install the direct clutch piston to the direct clutch drum sub-assembly.
- Coat a new O-ring with ATF, and install it to the No. 2 clutch balancer.
- Install the direct clutch piston return spring sub-assembly and No. 2 clutch balancer to the direct clutch drum sub-assembly.
- Place SST on the No. 2 clutch balancer and compress the return spring with a press.
SST 09387-00020
- Using SST, install the snap ring.
SST 09350-30020 (09350-07070)
- INSTALL NO. 2 CLUTCH DISC SET
- Install the 6 plates, 6 discs and flange to the direct clutch drum.
Install in order:
P - D - P - D - P - D - P - D - P - D - P - D - F
HINT:
P = Plate
D = Disc
F = Flange
NOTE: Before assembling new discs, soak them in ATF for at least 2 hours.
- Install the 6 plates, 6 discs and flange to the direct clutch drum.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
