- Using SST, tap in the bearing to the transmission case.
SST 09316-60011 (09316-00011,09316-00021)
- Using needle-nose pliers, install the snap ring.
- Using SST, tap in the bearing to the transmission case.
- INSTALL AUTOMATIC TRANSMISSION REAR OIL SEAL
- Coat the lip of a new oil seal with MP grease.
- Using SST and a hammer, tap in the oil seal until it fits with the transmission case.
SST 09214-76011
Standard oil seal depth:
3.5 +/-0.2 mm (0.138 +/- 0.008 in.)
- INSTALL NO. 2 BRAKE PISTON
- Coat 3 new O-rings with ATF, and install them to the brake piston.
- Install the brake piston to the transmission case.
HINT:
Make sure that the parking hole of the brake piston is on the bottom side by engaging the brake piston's 2 protrusions to the transmission case's spline grooves. (One groove is 3 places clockwise from the top, and the other is 2 places clockwise from the bottom).
- Install the brake return spring to the transmission case.
- Set SST on the 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:
14.77 to 15.37 mm (0.5815 to 0.6051 in.)
- Assemble the 4 No. 2 brakes discs, 3 No. 2 brake plates, and No. 2 brake flange as shown in the illustration. Then with a weight fixture 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 so that the value of measured length A minus length B (from steps *1 and *2) is 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 rear clutch drum sub-assembly.
- Coat a new O-ring with ATF, and install it to the clutch piston.
- Install the clutch piston to the rear 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 balancer to the rear clutch drum sub-assembly.
- Place SST on the 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 rear 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 rear 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.
