AUTOMATIC TRANSMISSION FLUID (ATF) K REPLACEMENT 1. On level ground, jack up the vehicle and support it evenly on safety stands. 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. 2. Loosen the oil pan installation bolts, and drain the ATF into a container. 3. Remove the oil pan and gasket. 4. Clean the oil pan and the magnet. 5. Install the oil pan along with a new gasket. Tightening torque: 5.9-7.8 N-m (60-80 kgfecm, 53-69 in-lbf) 6. Add approximately 4.0 L (4.2 US qt, 3.5 Imp qt} ATF, and check the ATF level. (Refer to page K-35.) Specified ATF: DexronmII or M-I11 Gartner Banana

TRANSMISSION TRANSMISSION UNIT (DISASSEMBLY) Preparation SST 49 H075 4958 Body (Part of 49 U019 OAOA) For disassembly of transmission For disassembly of transmission For disassembly of transmission 49 U019 OAOA Hanger set, transmission 49 U019 003 Holder (Part of 49 U019 OAOA) For disassembly of transmission For disassembly of transmission Precaution General notes: 1. The oil pan could contain small chips, shavings, and other particles helpful in checking the condition of the transmission and diagnosing certain problems. To ensure that all foreign particles stay in the oil pan, make sure that the transmission is never tipped completely over while the oil pan is still installed. L/ 2. Disassemble transmission in a clean area (dust proof work space) to prevent entry of dust into the mech- anisms. 3. Inspect the individual transmission components in accordance with the QUICK DIAGNOSIS CHART during disassembly. 4. Use only plastic hammers when applying force to separate the light alloy case joints. 5. Never use rags during disassembly; they may leave particles that can clog fluid passages. 6. Several parts resemble one another; organize them so they do not get mixed up. 7. Disassemble the control valve assembly and thoroughly clean it when a clutch or brake band is burned; or when the ATF has degenerated. Cleaning notes: 1. Clean the transmission exterior thoroughly with steam or cleaning solvents, or both, before disassembly. Warning Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air. 2. Clean the removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages with compressed air, and check that there are no obstructions. Gartner Banana

K TRANSMISSION DIRECT CLUTCH Preparation SST CLOCKWISE 49 0378 375 Compressor, clutch spring Preinspection Direct clutch operation 1. Install the direct clutch onto the drum support along with the seal rings. Apply compressed air through the oil passage as shown. For removal 1 installation of direct clutch Air pressure: 392 kPa (4.0 kgtcm*, 57 psi) max. 2. Verify that the side plate moves toward the snap ring. If not, the seal ring or O-ring may be damaged or fluid may be leaking at the piston check ball. Inspect them, and re- place as necessary when assembling. Clearance between side plate and snap ring 1. Measure the clearance between the side plate and the snap ring. Clearance Maximum: 0.2mm (0.008 in) i -, 2. Select and install the correct side plate when assern- bling. One-way clutch operation Insert the fourth gear clutch hub on the top of the direct clutch, and verify that the fourth gear clutch hub rotates smoothly when turned clockwise and locks when turned counterclockwise. If not, replace the one-way clutch. Gartner Banana
