K TRANSMISSION On-vehicle Removal 1. Disconnect the negative battery cable. 2. On level ground, jack up the vehicle and support it evenly on safety stands. w 3. Remove the exhaust pipe. (Refer to page K-45.) Warning When the transmission and the ATF are hot, they can cause burns to the skin. Allow the transmis- sion and the ATF to cool before doing this proce- dure. 4. Loosen the oil pan installation bolts, and drain the ATF into a container. 5. Disconnect the vacuum hose. 6. Remove the vacuum diaphragm, O-rings, and vacuum diaphragm rod. 7. Remove the oil pan, and the gasket. 8. Disconnect the solenoid valve connector. 9. Remove the harness from the bracket. 10. Remove the control valve body assembly. Gartner Banana

TRANSMISSION K On-vehicle Installation 1. Set the valve body assembly in position, and align the manual plate and manual valve. Tightening torque: 10.8-1 4.7 N.m (11 0-150 kgf-m, 95.5--130 ftalbf) 2. Connect the solenoid valve connector. 3. Install the harness. , . 4. Install the oil pan along with a new gasket. MANUAL PLATE Tightening torque: 5.9-7.8 N.m (60-80 kgf-cm, 53-69 in4bf) 45UOKX-371 5. Install the bolts. Tightening torque: 5.9-7.8 Nsm (60--80 kgf-cm, 53--69 inalbf) 6. Apply ATF to a new O-ring and install it onto the vacuum diaphragm. 7. Apply ATF to a new O-ring and install it into the transmis- sion case. 8. Apply ATF to the vacuum diaphragm rod and vacuum di- aphragm, and install them into the transmission case. Tightening torque: 7.9-1 0.7 N-m (80-1 10 kgf-cm, 70-95.4 in-lbf) 9. Connect the vacuum hose. 10. Install the exhaust pipe. (Refer to page K-148.) 11. Add approximately 4.0 L (4.2 US qt, 3.5 Imp qt) ATF, and check the ATF level. (Refer to page K-35.) Gartner Banana

K TRANSMISSION VACUUM DIAPHRAGM Preparation SST Note Excessive shift shock and improper shifting often indicate a vacuum diaphragm malfunction. 49 GO32 355 Adjustment gauge Warning When the transmission and the ATF are hot, they can cause burns to the skin. Allow the trans- mission and the ATF to cool before doing this procedure. For adjustment of vacuum diaphragm rod On-vehicle Removal 1. On level ground, jack up the vehicle and support it evenly on safety stands. 2. Remove the exhaust pipe. (Refer to page K-45.) 3. Loosen the oil pan mounting bolts, and drain approx. 1.0 L (1.1 US qt, 0.9 Imp qt) of ATF. L' 4. Disconnect the vacuum hose. 5. Remove the vacuum diaphragm, O-rings, and vacuum diaphragm rod. Inspection 1. Check that the vacuum diaphragm rod moves when vac- uum is applied to the vacuum diaphragm. 2. If not correct, replace the vacuum diaphragm. Gartner Banana

K TRANSMISSION Assembly Procedure 1. Assemble the SST as shown. 2. Mount the transmission case onto the SST. 3. Apply petroleum jelly to the bearing, and install it into the rear of the transmission case with the black surface fat- ing outward. Bearing outer diameter: 53.0mm (2.087 in) 4. Install the oil distributor in the transmission case. 5. Insert the output shaft. 6. Install the rear planetary gear unit (connecting drum, rear planetary pinion carrier and one-way clutch) in the low and reverse brake side. Gartner Banana

K TRANSMISSION I BEARING I SENSING ROTOR FOURTH GEAR CASE BEARING 19. Align the marks of the transmission case and fourth gear case. Tap lightly with a plastic hammer to avoid damag- ing the seal rings when installing. 20. Set a new gasket in place. Note The sensing rotor and bearing are part of the oil pump assembly. 21. Check and adjust the fourth gear planetary gear unit to- tal end play. Do not install the direct clutch drum at this .-, time. (1) Position the fourth gear case upright. (2) Install the bearing and race on the fourth gear case. (3) Install the planetary carrier, sun gear, connecting shell, and bearing as unit in the fourth gear case. (4) Install the sensing rotor and bearing on the connect- ing shell. (5) Measure distances E and H with a straightedge and vernier calipers. (6) Calculate the fourth gear train total end play by using the formula below. Formula: T=E-H-O.1 mm (0.0039 in) T Total end play. E: The distance between the oil pump mounting sur- face (including the oil pump gasket) and the sensing rotor bearing surface. H: The distance between the oil pump side sensing ro- tor bearing contact surface and the oil pump gasket contact surface. 0.1 :The compression amount of a new gasket. Total end play: 0.25-0.50mm (0.01 0-0.020 in} Gartner Banana
