Disassembly
1. Disconnect the transmission housing from the torque converter housing.
2. Remove multi-plate clutches K1, K2 and K3.
3. Remove the two visible Teflon rings upwards (42b) from the output shaft.
4. Remove retaining ring (42f), gasket (42s), thrust needle bearing (42d) and thrust pad (42s) from the output shaft.
5. Remove clutch K3 (44).
6. Remove the rear hollow shaft (45) from the output shaft.
7. Remove the rear planetary gear assembly (43) with built-in hollow shaft, central block of planetary gears from the output shaft.
8. Remove the thrust pad (43a).
9. Remove B1 multi-disc brake and oil pump.
Assembly
1. Install thrust washer (43a) cuff towards the carrier.
2. Install the rear planetary gear assembly (43) with built-in hollow shaft, central planetary gear set to output shaft.
3. Lubricate and install the three lower Teflon rings (42b) into the groove so that they fit together.
4. Install the rear hollow shaft (45) to the output shaft. Check the O-rings on the hollow shaft and replace them if necessary.
5. Install the K3 clutches.
6. Install snap ring, gasket, thrust needle bearing and thrust washer.
7. Lubricate and install the top two Teflon rings (42b) into the groove so that they fit together.
8. Check the axial clearance between the gasket (42s) and retaining ring (42f). It should be 0.15 - 0.6 mm. Adjust clearance with shim (42s). Gasket thickness: 3.0, 3.4 and 3.7 mm.
9. Install multi-plate clutches K1, K2 and K3.
